  • Plasma concentration of amino-terminal pro-brain natriuretic peptide in chronic heart failure: prediction of cardiovascular events and interaction with the effects of rosuvastatin: a report from CORONA (Controlled Rosuvastatin Multinational Trial in Heart Failure).
  • 2009
  • Ingår i: Journal of the American College of Cardiology. - : Elsevier BV. - 1558-3597 .- 0735-1097. ; 54:20, s. 1850-9
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: We investigated whether plasma amino-terminal pro-brain natriuretic peptide (NT-proBNP), a marker of cardiac dysfunction and prognosis measured in CORONA (Controlled Rosuvastatin Multinational Trial in Heart Failure), could be used to identify the severity of heart failure at which statins become ineffective. BACKGROUND: Statins reduce cardiovascular morbidity and mortality in many patients with ischemic heart disease but not, overall, those with heart failure. There must be a transition point at which treatment with a statin becomes futile. METHODS: In CORONA, patients with heart failure, reduced left ventricular ejection fraction, and ischemic heart disease were randomly assigned to 10 mg/day rosuvastatin or placebo. The primary composite outcome was cardiovascular death, nonfatal myocardial infarction, or stroke. RESULTS: Of 5,011 patients enrolled, NT-proBNP was measured in 3,664 (73%). The midtertile included values between 103 pmol/l (868 pg/ml) and 277 pmol/l (2,348 pg/ml). Log NT-proBNP was the strongest predictor (per log unit) of every outcome assessed but was strongest for death from worsening heart failure (hazard ratio [HR]: 1.99; 95% confidence interval [CI]: 1.71 to 2.30), was weaker for sudden death (HR: 1.69; 95% CI: 1.52 to 1.88), and was weakest for atherothrombotic events (HR: 1.24; 95% CI: 1.10 to 1.40). Patients in the lowest tertile of NT-proBNP had the best prognosis and, if assigned to rosuvastatin rather than placebo, had a greater reduction in the primary end point (HR: 0.65; 95% CI: 0.47 to 0.88) than patients in the other tertiles (heterogeneity test, p = 0.0192). This reflected fewer atherothrombotic events and sudden deaths with rosuvastatin. CONCLUSIONS: Patients with heart failure due to ischemic heart disease who have NT-proBNP values <103 pmol/l (868 pg/ml) may benefit from rosuvastatin.

  • 2007
  • Ingår i: The New England journal of medicine. - 1533-4406. ; 357:22, s. 2248-61
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Patients with systolic heart failure have generally been excluded from statin trials. Acute coronary events are uncommon in this population, and statins have theoretical risks in these patients. METHODS: A total of 5011 patients at least 60 years of age with New York Heart Association class II, III, or IV ischemic, systolic heart failure were randomly assigned to receive 10 mg of rosuvastatin or placebo per day. The primary composite outcome was death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke. Secondary outcomes included death from any cause, any coronary event, death from cardiovascular causes, and the number of hospitalizations. RESULTS: As compared with the placebo group, patients in the rosuvastatin group had decreased levels of low-density lipoprotein cholesterol (difference between groups, 45.0%; P<0.001) and of high-sensitivity C-reactive protein (difference between groups, 37.1%; P<0.001). During a median follow-up of 32.8 months, the primary outcome occurred in 692 patients in the rosuvastatin group and 732 in the placebo group (hazard ratio, 0.92; 95% confidence interval [CI], 0.83 to 1.02; P=0.12), and 728 patients and 759 patients, respectively, died (hazard ratio, 0.95; 95% CI, 0.86 to 1.05; P=0.31). There were no significant differences between the two groups in the coronary outcome or death from cardiovascular causes. In a prespecified secondary analysis, there were fewer hospitalizations for cardiovascular causes in the rosuvastatin group (2193) than in the placebo group (2564) (P<0.001). No excessive episodes of muscle-related or other adverse events occurred in the rosuvastatin group. CONCLUSIONS: Rosuvastatin did not reduce the primary outcome or the number of deaths from any cause in older patients with systolic heart failure, although the drug did reduce the number of cardiovascular hospitalizations. The drug did not cause safety problems. (ClinicalTrials.gov number, NCT00206310.)

  • Soluble ST2 is associated with adverse outcome in patients with heart failure of ischaemic aetiology
  • 2012
  • Ingår i: European Journal of Heart Failure. - : Wiley. - 1388-9842 .- 1879-0844. ; 14:3, s. 268-277
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims: In patients with ischaemic heart failure (HF), myocardial dysfunction often progresses. Elevated levels of soluble ST2 (sST2) are associated with a poor prognosis, but an association between sST2 and worsening heart failure per se has not been established. We assessed the association between sST2 and cause-specific outcome in 1449 patients enrolled in the Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA study). Methods and results: Soluble ST2 was measured with a highly sensitive immunoassay in 1449 patients ≥60 years of age with left ventricular ejection fraction (LVEF) ≤40% due to ischaemic heart disease. By Cox regression analyses, we found sST2 to be associated with the primary endpoint, i.e. a composite of cadiovascular (CV) death, non-fatal myocardial infarction, or stroke, as well as all pre-defined secondary endpoints in the CORONA study, even after adjustment for baseline clinical variables. After adjustment for N-terminal pro brain natriuretic peptide and C-reactive protein, the association between sST2 and the primary endpoint was attenuated and no longer statistically significant. However, sST2 remained associated with death due to worsening HF, hospitalization due to worsening HF, and hospitalization due to any CV cause, even after full adjustment. Conclusions: Soluble ST2 is associated with adverse outcomes in older patients with systolic, ischaemic HF. In particular, sST2 is independently associated with worsening HF. © The Author 2012.

  • Impact of Renal Impairment on Beta-Blocker Efficacy in PatientsWithHeartFailure.
  • 2019
  • Ingår i: Journal of the American College of Cardiology. - : Elsevier BV. - 1558-3597 .- 0735-1097. ; 74:23, s. 2893-2904
  • Tidskriftsartikel (refereegranskat)abstract
    • Moderate and moderately severe renal impairment are common in patients with heart failure and reduced ejection fraction, but whether beta-blockers are effective is unclear, leading to underuse of life-saving therapy.This study sought to investigate patient prognosis and the efficacy of beta-blockers according to renal function using estimated glomerular filtration rate (eGFR).Analysis of 16,740 individual patients with left ventricular ejection fraction<50% from 10 double-blind, placebo-controlled trials was performed. The authors report all-cause mortality on an intention-to-treat basis, adjusted for baseline covariates and stratified by heart rhythm.Median eGFR at baseline was 63 (interquartile range: 50 to 77) ml/min/1.73m2; 4,584 patients (27.4%) had eGFR 45 to 59ml/min/1.73m2, and 2,286 (13.7%) 30 to 44ml/min/1.73m2. Over a median follow-up of 1.3 years, eGFR was independently associated with mortality, with a 12% higher risk of death for every 10ml/min/1.73m2 lower eGFR (95% confidence interval [CI]: 10% to 15%; p<0.001). In 13,861 patients in sinus rhythm, beta-blockers reduced mortality versus placebo; adjusted hazard ratio (HR): 0.73 for eGFR 45 to 59ml/min/1.73m2 (95%CI: 0.62 to 0.86; p<0.001) and 0.71 for eGFR 30 to 44ml/min/1.73m2 (95%CI: 0.58 to 0.87; p=0.001). The authors observed no deterioration in renal function over time in patients with moderate or moderately severe renal impairment, no difference in adverse events comparing beta-blockers with placebo, and higher mortality in patients with worsening renal functionon follow-up. Due to exclusion criteria, there were insufficient patients with severe renal dysfunction (eGFR<30ml/min/1.73m2) to draw conclusions. In 2,879 patients with atrial fibrillation, there was no reduction in mortality with beta-blockers at any level of eGFR.Patients with heart failure, left ventricular ejection fraction<50% and sinus rhythm should receivebeta-blocker therapy even with moderate or moderately severe renal dysfunction.

  • An economic evaluation of rosuvastatin treatment in systolic heart failure: evidence from the CORONA trial.
  • 2010
  • Ingår i: European journal of heart failure. - : Wiley. - 1879-0844 .- 1388-9842. ; 12:1, s. 66-74

    • AIMS: To estimate the cost-effectiveness of 10 mg rosuvastatin daily for older patients with systolic heart failure in the Controlled Rosuvastatin Multinational Study in Heart Failure (CORONA) trial. METHODS AND RESULTS: This within trial analysis of CORONA used major cardiovascular (CV) events as the outcome measure. Resource use was valued and the costs of hospitalizations, procedures, and statin use compared. Cost-effectiveness was estimated as cost per major CV event avoided. There were significantly fewer major CV events in the rosuvastatin group compared with the placebo group (1.04 vs. 1.20 per patient; difference 0.164; 95% CI: 0.075-0.254, P < 0.001). The average cost of CV hospitalizations and procedures was significantly lower for those receiving rosuvastatin ( pound1531 vs. pound1769; difference pound238; 95% CI: pound73-403, P = 0.005); the additional cost of the statin resulted in significantly higher total costs for the rosuvastatin group ( pound1769 vs. pound2072; difference pound303; 95% CI: pound138-468, P < 0.001). Overall, rosuvastatin was found to cost pound1840 (95% CI: pound562-6028) per major CV event avoided. CONCLUSION: This economic analysis showed that a significant reduction in major CV events with rosuvastatin led to significantly reduced costs of CV hospitalizations and procedures. The reduction in associated costs for major CV events was found to offset partially (by 44%) the cost of rosuvastatin treatment in patients with systolic heart failure.

  • Effects of statin therapy according to plasma high-sensitivity C-reactive protein concentration in the Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA): a retrospective analysis.
  • 2009
  • Ingår i: Circulation. - 1524-4539. ; 120:22, s. 2188-96
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: We examined whether the antiinflammatory action of statins may be of benefit in heart failure, a state characterized by inflammation in which low cholesterol is associated with worse outcomes. METHODS AND RESULTS: We compared 10 mg rosuvastatin daily with placebo in patients with ischemic systolic heart failure according to baseline high sensitivity-C reactive protein (hs-CRP) <2.0 mg/L (placebo, n=779; rosuvastatin, n=777) or > or = 2.0 mg/L (placebo, n=1694; rosuvastatin, n=1711). The primary outcome was cardiovascular death, myocardial infarction, or stroke. Baseline low-density lipoprotein was the same, and rosuvastatin reduced low-density lipoprotein by 47% in both hs-CRP groups. Median hs-CRP was 1.10 mg/L in the lower and 5.60 mg/L in the higher hs-CRP group, with higher hs-CRP associated with worse outcomes. The change in hs-CRP with rosuvastatin from baseline to 3 months was -6% in the low hs-CRP group (27% with placebo) and -33.3% in the high hs-CRP group (-11.1% with placebo). In the high hs-CRP group, 548 placebo-treated (14.0 per 100 patient-years of follow-up) and 498 rosuvastatin-treated (12.2 per 100 patient-years of follow-up) patients had a primary end point (hazard ratio of placebo to rosuvastatin, 0.87; 95% confidence interval, 0.77 to 0.98; P=0.024). In the low hs-CRP group, 175 placebo-treated (8.9 per 100 patient-years of follow-up) and 188 rosuvastatin-treated (9.8 per 100 patient-years of follow-up) patients experienced this outcome (hazard ratio, 1.09; 95% confidence interval, 0.89 to 1.34; P>0.2; P for interaction=0.062). The numbers of deaths were as follows: 581 placebo-treated (14.1 per 100 patient-years of follow-up) and 532 rosuvastatin-treated (12.6 per 100 patient-years) patients in the high hs-CRP group (hazard ratio, 0.89; 95% confidence interval, 0.79 to 1.00; P=0.050) and 170 placebo-treated (8.3 per 100 patient-years) and 192 rosuvastatin-treated (9.7 per 100 patient-years) patients in the low hs-CRP group (hazard ratio, 1.17; 95% confidence interval, 0.95 to 1.43; P=0.14; P for interaction=0.026). CONCLUSIONS: In this retrospective hypothesis-generating study, we found a significant interaction between hs-CRP and the effect of rosuvastatin for most end points whereby rosuvastatin treatment was associated with better outcomes in patients with hs-CRP > or = 2.0 mg/L.

  • The influence of renal function on clinical outcome and response to beta-blockade in systolic heart failure: insights from Metoprolol CR/XL Randomized Intervention Trial in Chronic HF (MERIT-HF).
  • 2009
  • Ingår i: Journal of cardiac failure. - : Elsevier BV. - 1532-8414 .- 1071-9164. ; 15:4, s. 310-8
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Limited information is available on the risk and impact of renal dysfunction on the response to beta-blockade and mode of death in systolic heart failure (HF). METHODS AND RESULTS: Renal function was estimated with glomerular filtration rate (eGFR) using the simplified Modification of Diet in Renal Disease (MDRD) equation. Patients from the Metoprolol CR/XL Controlled Randomized Intervention Trial in Chronic HF (MERIT-HF) were divided into 3 renal function subgroups (MDRD formula): eGFR(MDRD) > 60 (n = 2496), eGFR(MDRD) 45 to 60 (n = 976), and eGFR(MDRD) < 45 mL/min per 1.73 m(2) body surface area (n = 493). Hazard ratio (HR) was estimated with Cox proportional hazards models adjusted for prespecified risk factors. Placebo patients with eGFR < 45 had significantly higher risk than those with eGFR > 60: HR for all-cause mortality, 1.90 (95% confidence interval [CI], 1.28 to 2.81) comparing placebo patients with eGFR < 45 and eGFR > 60, and for the combined end point of all-cause mortality/hospitalization for worsening HF (time to first event): HR, 1.91 (95% CI, 1.44 to 2.53). No significant increase in risk with deceased renal function was observed for those randomized to metoprolol controlled release (CR)/extended release (XL) due to a highly significant decrease in risk on metoprolol CR/XL in those with eGFR < 45. For total mortality, metoprolol CR/XL vs placebo: HR, 0.41 (95% CI. 0.25 to 0.68; P < .001) in those with eGFR < 45 compared with HR, 0.71 (95% CI, 0.54 to 0.95; P < .021) for those with eGFR > 60; corresponding data for the combined end point was HR, 0.44 (95% CI, 0.31 to 0.63; P < .0001) and HR, 0.75 (0.62 to 0.92; P = .005, respectively; P = .095 for interaction by treatment for total mortality; P = .011 for combined end point). Metoprolol CR/XL was well tolerated in all 3 renal function subgroups. CONCLUSIONS: Renal function as estimated by eGFR was a powerful predictor of death and hospitalizations from worsening HF. Metoprolol CR/XL was at least as effective in reducing death and hospitalizations for worsening HF in patients with eGFR < 45 as in those with eGFR > 60.

  • An Investigation of CYP2D6 Genotype and Response to Metoprolol CR/XL During Dose Titration in Patients With Heart Failure: A MERIT-HF Substudy
  • 2014
  • Ingår i: Clinical Pharmacology & Therapeutics. - : Springer Science and Business Media LLC. - 0009-9236 .- 1532-6535. ; 95:3, s. 321-330

    • To explore the pharmacogenetic effects of the cytochrome P450 (CYP) 2D6 genotype in patients with systolic heart failure treated using controlled/extended-release (CR/XL) metoprolol, this study assessed the CYP2D6 locus for the nonfunctional * 4 allele (1846G> A; rs3892097) in the Metoprolol CR/XL Randomised Intervention Trial in Congestive Heart Failure (MERIT-HF; n = 605). Participants were characterized as extensive, intermediate, or poor metabolizers (EMs, IMs, or PMs, respectively), based on the presence of the CYP2D6* 4 allele (EM: * 1* 1, 60.4%; IM: * 1* 4, 35.8%; and PM: * 4* 4, 3.8%). Plasma metoprolol concentrations were 2.1-/4.6-fold greater in the IM/PM groups as compared with the EM group (P < 0.0001). Metoprolol induced significantly lower heart rates and diastolic blood pressures during early titration, indicating a CYP2D6* 4 allele dose-response effect (P < 0.05). These effects were not observed at maximal dose, suggesting a saturable effect. Genotype did not adversely affect surrogate treatment efficacy. CYP2D6 genotype modulates metoprolol pharmacokinetics/pharmacodynamics during early titration; however, the MERIT-HF-defined titration schedule remains recommended for all patients, regardless of genotype.

  • Efficacy, safety and tolerability of beta-adrenergic blockade with metoprolol CR/XL in elderly patients with heart failure
  • 2004
  • Ingår i: Eur Heart J. - : Oxford University Press (OUP). - 0195-668X. ; 25:15, s. 1300-9
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM: To study the efficacy and tolerability of beta-blockade in elderly patients with heart failure in the MERIT-HF study. METHODS AND RESULTS: Cox proportional hazards model was used to calculate hazard ratios (HR) with 95% confidence intervals (CI). Risk reduction was defined as (1-HR). In patients > or = 65 years total mortality was reduced by 37% (95% CI 17% to 52%; p=0.0008), sudden death by 43% (95% CI 17% to 61%; p=0.0032), and death from worsening heart failure by 61% (95% CI 32% to 77%; p=0.0005). Hospitalisations for worsening heart failure was reduced by 36% (p=0.0006). Elderly patients with severe heart failure (NYHA class III/IV with ejection fraction < 0.25; n=425, and patients above 75 years (n=490) showed similar risk reductions. Metoprolol CR/XL was safe and well tolerated both during initiating therapy and during long-term follow-up. CONCLUSIONS: Metoprolol CR/XL was easily instituted, safe and well tolerated in elderly patients with systolic heart failure. The data suggest that these are the patients in whom treatment will have the greatest impact as shown by number of lives saved and number of hospitalisations avoided. The time has come to overcome the barriers that physicians perceive to beta-blocker treatment, and to provide it to the large number of elderly patients with heart failure in need of this therapy.

  • Consistency of the beneficial effect of metoprolol succinate extended release across a wide range dose of angiotensin-converting enzyme inhibitors and digitalis
  • 2004
  • Ingår i: J Card Fail. - 1071-9164. ; 10:6, s. 452-9
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The effects of beta-blockade with different extent of angiotensin-converting enzyme inhibitors (ACEI) and digitalization are unknown. To assess the effect of metoprolol succinate controlled release/extended release (CR/XL) combined with high versus low doses of ACEI and digitalis, we analyzed data from The Metoprolol CR/XL Randomized Intervention Trial in Chronic Heart Failure (MERIT-HF) in which patients with heart failure and left ventricular ejection fraction < or =40% were randomized to metoprolol CR/XL versus placebo. METHODS AND RESULTS: Outcome was analyzed separately for those on a low dose (< or =median) of the ACEI or digitalis versus high dose (> median). The mean dose of ACEI in the high-dose group (n = 1457) was 3 times higher than that in the low-dose group (n = 2094). Mortality was reduced to a similar extent in the high- and low-dose ACEI subgroups (RR = .69 versus .64, respectively). Corresponding figures for combined mortality/all hospitalization and for mortality/hospitalization for heart failure were .85 versus .83, and .70 versus .68, respectively. Likewise, reduction in total mortality with metoprolol CR/XL was similar in patients receiving no digitalis (n = 1447; RR = .56), low dose (n = 1122; RR = .71), or high dose (n = 1421; RR = .71). CONCLUSION: This analysis of MERIT-HF demonstrates consistent and similar improvement in outcome of patients receiving metoprolol CR/XL when combined with either a high or low dose of an ACEI or digitalis, or no digitalis at all. Thus regardless of ACEI and digitalis dose and whether patients are treated with digitalis or not, it is very important to add a beta-blocker to the existing heart failure therapy. beta-blockers should not be withheld until target doses of ACEI have been achieved.

  • A statin in the treatment of heart failure? Controlled rosuvastatin multinational study in heart failure (CORONA): study design and baseline characteristics
  • 2005
  • Ingår i: Eur J Heart Fail. - 1388-9842. ; 7:6, s. 1059-69
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Previous prospective outcome studies of statins have not provided any guidance on benefit-risk in patients with heart failure. AIM: The primary objective is to determine whether rosuvastatin (10 mg) reduces the combined endpoint of cardiovascular mortality, non-fatal myocardial infarction or non-fatal stroke (time to first event). The first secondary endpoint is all-cause mortality. METHODS: CORONA is a randomized, double-blind, placebo-controlled trial. Briefly, men and women, aged > or =60 years with chronic symptomatic systolic heart failure of ischemic aetiology and ejection fraction < or =0.40 (NYHA class III and IV) or < or =0.35 (NYHA class II) were eligible if they were not using or in need of cholesterol lowering drugs. RESULTS: Mean age was 73 years (n=5016; 24% women), with 37% in NYHA II and 62% in NYHA III, ejection fraction 0.31, total cholesterol 5.2 mmol/L. Sixty percent have a history of myocardial infarction, 63% hypertension, and 30% diabetes. Patients are well treated for heart failure with 90% on loop or thiazide diuretics, 42% aldosterone antagonists, 91% ACE inhibitor or AT-I blocker, 75% beta-blockers, and 32% digitalis. CONCLUSION: CORONA is important for three main reasons: (1) A positive result is very important because of the high risk of the population studied, the increasing prevalence of elderly patients with chronic symptomatic systolic heart failure in our society, and the health economic issues involved. (2) If negative, new mechanistic questions about heart failure have to be raised. (3) If neutral we can avoid unnecessary polypharmacy.

    • BACKGROUND: Our aim was to describe the incidence and predictors of stroke in patients who have heart failure without atrial fibrillation (AF). METHODS AND RESULTS: We pooled 2 contemporary heart failure trials, the Controlled Rosuvastatin in Multinational Trial Heart Failure (CORONA) and the Gruppo Italiano per lo Studio della Sopravvivenza nell'Insufficienza cardiaca-Heart Failure trial (GISSI-HF). Of the 9585 total patients, 6054 did not have AF. Stroke occurred in 165 patients (4.7%) with AF and in 206 patients (3.4%) without AF (rates 16.8/1000 patient-years and 11.1/1000 patient-years, respectively). Using Cox proportional-hazards models, we identified the following independent predictors of stroke in patients without AF (ranked by chi(2) value): age (hazard ratio, 1.34; 95% confidence interval, 1.18-1.63 per 10 years), New York Heart Association class (1.60, 1.21-2.12 class III/IV versus II), diabetes mellitus treated with insulin (1.87, 1.22-2.88), body mass index (0.74, 0.60-0.91 per 5 kg/m(2) up to 30), and previous stroke (1.81, 1.19-2.74). N-terminal pro B-type natriuretic peptide (available in 2632 patients) was also an independent predictor of stroke (hazard ratio, 1.31; 1.11-1.57 per log unit) when added to this model. With the use of a risk score formulated from these predictors, we found that patients in the upper third of risk had a rate of stroke that approximated the risk in patients with AF. CONCLUSIONS: A small number of demographic and clinical variables identified a subset of patients who have heart failure without AF at a high risk of stroke.

    • The objective of this cross-sectional study was to investigate the relationship between factors of the coagulation- and fibrinolysis systems and insulin sensitivity in 104 clinically healthy, 58-years-old men. Insulin sensitivity (hyperinsulinemic euglycemic clamp) adjusted for lean body mass, the metabolic syndrome according to a suggested definition, and different factors in the coagulation- and fibrinolysis system were determined. Subjects with the metabolic syndrome were characterised by increases in PAI-1 activity, tPA antigen, protein C and protein S and low concentrations of tPA activity. Insulin sensitivity was independently and reversibly associated with PAI-1 (p = 0.014) and directly with tPA activity (p = 0.001). Insulin sensitivity was also significantly negatively associated with protein S and protein C and several components in the metabolic syndrome, however not remaining significant in multivariate analyses. Protein C and protein S were significantly associated with PAI-1 activity, tPA activity (negatively), tPA antigen and antithrombin III. In conclusion, the data indicated that insulin resistance and several of the clustering components in the metabolic syndrome are accompanied by increased plasma concentrations of the anticoagulatory proteins C and S which may represent a mechanism which counteracts the concomitantly occurring hypofibrinolysis.

    • OBJECTIVES: The objective was to analyse whether a favourable change in risk factors, caused by a comprehensive risk factor modification programme, affected intima-media thickness (IMT) in the common carotid artery, and whether any such change was associated with a change in cardiovascular events during a 6-year follow-up. DESIGN: Patients were randomized 1 : 1 to special intervention or usual care. SETTING: Hypertension Unit at university hospital. SUBJECTS: A total of 164 patients were randomized. Inclusion criteria were male, aged 50-72 years (at randomization) and one or more of the following: Serum cholesterol level > 6.5 mmol L(-1), smoking or diabetes mellitus. All patients were prescribed antihypertensive treatment since many years. In 142 men good quality ultrasound recording of the common carotid IMT were achieved at baseline, 119 were re-examined after 3.3 years, and 97 patients were available for examination after mean follow-up time of 6.2 years. Cardiovascular events were available for all randomized patients. INTERVENTIONS: The nonpharmacological special intervention programme was based on one information meeting followed by five weekly 2-h sessions with participation of patients and spouses. The diet recommendations were similar to established guidelines. Overweight patients were instructed to lose weight, and diabetic patients were systematically taught self-monitoring of blood glucose. Smokers were invited to a smoking cessation programme with five weekly meetings. Follow-up visits were thereafter scheduled every 6 months. Lipid lowering drugs were recommended in the intervention group if the treatment goals using nonpharmacological measures were not achieved. Patients in the usual care group were told to quit smoking and to lower their consumption of fat and glucose. Antihypertensive treatment (i.e., selection of drugs) was on purpose kept similar in the two groups. MAIN OUTCOME MEASURES: The IMT of the common carotid artery as measured by ultrasound. Cardiovascular events during follow-up. RESULTS: Significant net reductions were seen for serum cholesterol, triglycerides, fasting glucose and smoking. No difference in change in IMT was observed during follow-up between the two randomization groups. The explanation was that patients with positive plaque status at baseline had a much larger increase in IMT over time than patients with negative plaque status, and that patients with positive plaque status more often survived and were available for re-examination after 6 years in the intervention group than in the usual care group. Total mortality was lower in the intervention group, compared with the usual care group, 13 and 29%, respectively (P=0.028). CONCLUSIONS: In high risk populations, long-term studies with surrogate endpoints may be misleading because of missing data in patients where a large increase in IMT would have been observed, had they been re-examined. Another important conclusion from our study was that the gloomy prognosis for this patient category may be improved by a dedicated risk factor intervention programme. The improved prognosis was observed mainly in those patients at highest risk judged from history of cardiovascular disease or positive ultrasound plaque status at baseline.

  • Dose-related effects of metoprolol on heart rate and pharmacokinetics in heart failure.

    • The pharmacokinetics and pharmacodynamics of immediate-release (IR) metoprolol, 50 mg 3 times daily, were compared with those of different doses of controlled-release/extended-release metoprolol (CR/XL) given once daily.Fifteen patients with chronic heart failure were randomized to a 3-way crossover study to receive metoprolol IR 50 mg 3 times daily, CR/XL 100 mg once daily, and CR/XL 200 mg once daily for 7 days. On the seventh day of each treatment, serial plasma samples were drawn and standardized exercise tests and a 24-hour Holter recording were performed. Metoprolol IR 50 mg produced peak plasma levels comparable to those observed for CR/XL 200 mg (285 v 263 nmol/L). The difference in mean 24-hour heart rate between CR/XL 100 mg and IR 50 mg was 1.0 bpm (95% confidence interval [CI]), -2.9 to 4.9; NS) compared with -3.8 bpm (95% CI, -7.6 to -0.04; P = .048) between CR/XL 200 mg and IR 50 mg. Submaximal exercise heart rate was lower for patients receiving CR/XL 200 mg than those receiving IR 50 mg. No difference in tolerance or exercise performance was observed between treatment regimens.Peak plasma levels produced by metoprolol 200 mg CR/XL were similar to those of 50 mg IR. Metoprolol CR/XL 200 mg was associated with a more pronounced suppression of heart rate than metoprolol IR 50 mg. It is suggested that patients can safely be switched from multiple dosing of metoprolol IR 50 mg to a once-daily dose of metoprolol CR/XL.

    • Aim Angina pectoris is common in patients with heart failure and reduced ejection fraction (HF-REF) but its relationship with outcomes has not been well defined. This relationship was investigated further in a retrospective analysis of the Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA). Methods and results Four thousand, eight hundred and seventy-eight patients were divided into three categories: no history of angina and no chest pain at baseline (Group A; n = 1240), past history of angina but no chest pain at baseline (Group B; n = 1353) and both a history of angina and chest pain at baseline (Group C; n = 2285). Outcomes were examined using Kaplan-Meier and Cox regression survival analysis. Compared with Group A, Group C had a higher risk of non-fatal myocardial infarction or unstable angina (HR: 2.36, 1.54-3.61; P<0.001), this composite plus coronary revascularization (HR: 2.54, 1.76-3.68; P<0.001), as well as HF hospitalization (HR: 1.35, 1.13-1.63; P = 0.001), over a median follow-up period of 33 months. There was no difference in cardiovascular or all-cause mortality. Group B had a smaller increase in risk of coronary events but not of heart failure hospitalization. Conclusion Patients with HF-REF and ongoing angina are at an increased risk of acute coronary syndrome and HF hospitalization. Whether these patients would benefit from more aggressive medical therapy or percutaneous revascularization is not known and merits further investigation.

  • Are serum adiponectin concentrations in a population sample of 64-year-old Caucasian women with varying glucose tolerance associated with ultrasound-assessed atherosclerosis?
  • 2006
  • Ingår i: J Intern Med. - : Wiley. - 0954-6820. ; 260:3, s. 238-44
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To examine whether serum adiponectin concentrations were associated with subclinical atherosclerosis assessed as intima media thickness (IMT) in the carotid arteries in Caucasian women with varying degrees of glucose tolerance. RESEARCH DESIGN AND METHODS: From a population-based cohort of 64-year-old Swedish women, 533 subjects with type 2 diabetes (DM2, n=177), impaired glucose tolerance (IGT; n=178) or normal glucose tolerance (NGT, n=178) were recruited. Anthropometrics, usual cardiovascular risk factors were examined and ultrasound examination of the carotid arteries was performed. RESULTS: Women with low adiponectin concentrations were characterized by thick IMT, higher prevalence of DM2, history of previous myocardial infarction, angina pectoris, anti-hypertensive treatment and high body mass index (BMI), waist circumference, plasma insulin, serum triglycerides, fasting glucose, HbA1c, and low serum HDL cholesterol levels. Carotid IMT correlated with HbA1c (r=0.24, P<0.001), waist circumference (r=0.22, P<0.001), plasma insulin (r=0.19, P<0.001), BMI (r=0.18, P<0.001), DM2 (r=0.16, P<0.001), systolic blood pressure (r=0.16, P<0.001), blood glucose (r=0.16, P<0.001), triglycerides (r=0.15, P<0.001), and reversely to adiponectin (r=-0.11, P=0.01), HDL cholesterol (r=-0.13, P=0.004), and alcohol intake (r=-0.087, P<0.05). A more detailed analysis of underlying associations was difficult due to a high co-linearity between these variable. CONCLUSIONS: Low serum adiponectin concentrations were associated with increased carotid artery IMT, and several risk factors for cardiovascular diseases, mainly those constituting the metabolic syndrome.

  • Ingår i: Nutrition, metabolism, and cardiovascular diseases : NMCD. - : Elsevier BV. - 1590-3729 .- 0939-4753. ; 19:5, s. 327-333

    • BACKGROUND AND AIMS: Impaired glucose tolerance (IGT) is regarded as a transient metabolic state leading to type-2 diabetes, and is known to predict future risk of cardiovascular disease. This study was designed to investigate if IGT is associated with subclinical atherosclerosis. METHODS AND RESULTS: In a population-based cohort of 64-year-old women, a group with IGT determined by repeated oral glucose tolerance tests (n=205) was compared with healthy women with normal glucose tolerance (NGT, n=188). Intima-media thickness (IMT) and plaques in the common carotid arteries (CCA) and bulbs were measured by ultrasound. The 95% confidence interval (CI) of the difference between the IGT and NGT groups was -0.03 to 0.03mm. There was no difference in carotid bulb IMT or in the occurrence, size, and characteristics of plaques between the IGT and NGT groups. A meta-analysis was used to calculate summary measures of 12 reviewed studies showing a difference of 0.030 (95% CI 0.012-0.048) mm in carotid IMT between IGT and NGT groups. Heterogeneity in IMT differences between studies was shown. CONCLUSIONS: In our population-based cohort of 64-year-old women, IGT was not associated with increased occurrence of subclinical atherosclerosis. However, a meta-analysis of 12 studies, including our current study, showed that IGT was associated with a small increase in the CCA IMT.

  • Prevalence of diabetes and impaired glucose tolerance in 64-year-old Swedish women: experiences of using repeated oral glucose tolerance tests
  • 2006
  • Ingår i: Diabetes Care. - 0149-5992. ; 29:2, s. 363-7
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: The purpose of this study was to describe the prevalence of diabetes and impaired glucose tolerance (IGT) in middle-aged women and to examine the variability and practical use of the oral glucose tolerance test (OGTT) in the screening for IGT and diabetes. RESEARCH DESIGN AND METHODS: All 64-year-old women living in Goteborg, Sweden, were invited to take part in a screening examination (n = 4,856). Of these, 82% (n = 3,998) responded and 53% (n = 2,595) participated and underwent anthropometric measurements and a 75-g standardized OGTT that was repeated within 2 weeks in those not showing normal glucose tolerance (NGT). RESULTS: The prevalences of known and new diabetes, IGT at both OGTTs, and impaired fasting glucose were 4.7, 4.8, 14.4, and 6.4%, respectively. Half of the women with diabetes were previously undiagnosed, and 37% of the diagnoses were based on OGTT and diabetes 2-h values at both or one of the two examinations. Women with IGT at both OGTTs, in comparison with those with one impaired and one normal OGTT, had higher BMI, waist girth, and blood pressure. More than 40% of the women showed impaired glucose metabolism. CONCLUSIONS: Among these women, the prevalence of undetected diabetes was high and repeated OGTTs were needed to identify and not misclassify a considerable proportion of patients. The degree of glucose tolerance impairment and the number of abnormal OGTTs were directly associated with occurrence of components of the metabolic syndrome.

  • Economic implications of extended-release metoprolol succinate for heart failure in the MERIT-HF trial: a US perspective of the MERIT-HF trial

  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The MERIT-HF trial demonstrated improved survival and fewer hospitalizations for worsening heart failure with extended-release (ER) metoprolol succinate in patients with heart failure. This study sought to estimate the economic implications of this trial from a US perspective. METHODS AND RESULTS: A discrete event simulation was developed to examine the course of patients with heart failure. Characteristics of the population modeled, probabilities of hospitalization and death with standard therapy, and risk reductions with ER metoprolol succinate were obtained from Metoprolol CR/XL Randomized Intervention Trial in Chronic Heart Failure (MERIT-HF) and evaluated in weekly cycles. Direct medical costs were estimated from US databases in 2001 US dollars. Uncertainty in inputs was incorporated and analyses were carried out to estimate events prevented total and net costs. The model predicts that ER metoprolol succinate will prevent approximately 7 deaths and 15 hospitalizations from heart failure per 100 patients over 2 years. Compared with standard therapy alone, this translates to a cost reduction between $395 and $1112 per patient, depending on whether the costs of hospitalizations for other causes are included. Savings were maintained in 90% of the simulations. CONCLUSION: This analysis predicts that the positive effect of ER metoprolol succinate on mortality and morbidity demonstrated in MERIT-HF leads to substantial savings.

    • Aims Recent guidelines recommend that patients with heart failure and left ventricular ejection fraction (LVEF) 40-49% should be managed similar to LVEF >= 50%. We investigated the effect of beta-blockers according to LVEF in double-blind, randomized, placebo-controlled trials. Methods and results Individual patient data meta-analysis of 11 trials, stratified by baseline LVEF and heart rhythm (Clinicaltrials.gov: NCT0083244; PROSPERO: CRD42014010012). Primary outcomes were all-cause mortality and cardiovascular death over 1.3 years median follow-up, with an intention-to-treat analysis. For 14 262 patients in sinus rhythm, median LVEF was 27% (interquartile range 21-33%), including 575 patients with LVEF 40-49% and 244 >= 50%. Beta-blockers reduced all-cause and cardiovascular mortality compared to placebo in sinus rhythm, an effect that was consistent across LVEF strata, except for those in the small subgroup with LVEF >= 50%. For LVEF 40-49%, death occurred in 21/292 [7.2%] randomized to beta-blockers compared to 35/283 [12.4%] with placebo; adjusted hazard ratio (HR) 0.59 [95% confidence interval (CI) 0.34-1.03]. Cardiovascular death occurred in 13/292 [4.5%] with beta-blockers and 26/283 [9.2%] with placebo; adjusted HR 0.48 (95% CI 0.24-0.97). Over a median of 1.0 years following randomization (n = 4601), LVEF increased with beta-blockers in all groups in sinus rhythm except LVEF >= 50%. For patients in atrial fibrillation at baseline (n = 3050), beta-blockers increased LVEF when < 50% at baseline, but did not improve prognosis. Conculations Beta-blockers improve LVEF and prognosis for patients with heart failure in sinus rhythm with a reduced LVEF. The data are most robust for LVEF < 40%, but similar benefit was observed in the subgroup of patients with LVEF 40-49%.

  • Tidskriftsartikel (refereegranskat)abstract
    • Aims Up to one-third of patients with diabetes mellitus and heart failure (HF) are treated with insulin. As insulin causes sodium retention and hypoglycaemia, its use might be associated with worse outcomes. Methods and results We examined two datasets: 24 012 patients with HF from four large randomized trials and an administrative database of 4 million individuals, 103 857 of whom with HF. In the former, survival was examined using Cox proportional hazards models adjusted for baseline variables and separately for propensity scores. Fine-Gray competing risk regression models were used to assess the risk of hospitalization for HF. For the latter, a case-control nested within a population-based cohort study was conducted with propensity score. Prevalence of diabetes mellitus at study entry ranged from 25.5% to 29.5% across trials. Insulin alone or in combination with oral hypoglycaemic drugs was prescribed at randomization to 24.4% to 34.5% of the patients with diabetes. The rates of death from any cause and hospitalization for HF were higher in patients with vs. without diabetes, and highest of all in patients prescribed insulin [propensity score pooled hazard ratio for all-cause mortality 1.27 (1.16-1.38), for HF hospitalization 1.23 (1.13-1.33)]. In the administrative registry, insulin prescription was associated with a higher risk of all-cause death [odds ratio (OR) 2.02, 95% confidence interval (CI) 1.87-2.19] and rehospitalization for HF (OR 1.42, 95% CI 1.32-1.53). Conclusions Whether insulin use is associated with poor outcomes in HF should be investigated further with controlled trials, as should the possibility that there may be safer alternative glucose-lowering treatments for patients with HF and type 2 diabetes mellitus.

    • BACKGROUND: The objective of the current study was to examine the efficacy and tolerability of the beta-blocker metoprolol succinate controlled release/extended release (CR/XL) in patients with diabetes in the Metoprolol CR/XL Randomized Intervention Trial in Chronic Heart Failure (MERIT-HF). METHODS: The Cox proportional hazards model was used to calculate hazard ratios (HR) for convenience expressed as relative risks (risk reduction = 1-HR), and 95% confidence intervals (CI). RESULTS: The risk of hospitalization for heart failure was 76% higher in diabetics compared to non-diabetics (95% CI 38% to 123%). Metoprolol CR/XL was well tolerated and reduced the risk of hospitalization for heart failure by 37% in the diabetic group (95% CI 53% to 15%), and by 35% in the non-diabetic group (95% CI 48% to 19%). Pooling of mortality data from the Cardiac Insufficiency Bisoprolol Study II (CIBIS II), MERIT-HF, and the Carvedilol Prospective Randomized Cumulative Survival Study (COPERNICUS) showed similar survival benefits in patients with diabetes (25%; 95% CI 40% to 4%) and without diabetes (36%; 95% CI 44% to 27%); test of diabetes by treatment interaction was non-significant. Adverse events were reported more often on placebo than on metoprolol CR/XL. CONCLUSIONS: Patients with heart failure and diabetes have a much higher risk of hospitalization than patients without diabetes. Regardless of diabetic status, a highly significant reduction in hospitalizations for heart failure was observed with metoprolol CR/XL therapy, which was very well tolerated also by patients with diabetes. Furthermore, the pooled data showed a statistically significant survival benefit in patients with diabetes.

    • Objectives . To examine the hypothesis that serum concentration of C-reactive protein (CRP) is inversely associated with insulin sensitivity and obesity, and that this may by mediated by tumor necrosis factor-alpha (TNFalpha) and interleukin-6 (IL-6). Material and methods . Cross-sectional, one-center study of a population-based sample of 58-year-old Swedish men (n = 98). Exclusion criteria were cardiovascular disease, clinical diabetes mellitus and/or continuous cardiovascular medication. Glucose infusion-rate (euglycemic hyperinsulinemic clamp), adjusted for fat-free mass, which together with total body fat was measured by dual-energy X-ray absorptiometry. Serum concentrations of CRP, TNFalpha, soluble TNFalpha receptor 2 (sTNFAR2), IL-6 determined by ELISA. Ultrasound was used to measure intima-media thickness (IMT) in both common carotid arteries, carotid bulbs and in the right femoral artery. Results . CRP was inversely associated with insulin sensitivity (r = -0.28, p<0.01) and with total body fat (r = 0.31, p<0.01), but not independently of the TNFalpha and sTNFAR2 product. Serum CRP, TNFalpha, sTNFAR2, but not IL-6, were associated with low insulin sensitivity, total body fat, abdominal obesity, hyperinsulinemia, hypertriglyceridemia, low HDL cholesterol and small LDL particles, i.e. the metabolic syndrome. These associations were independent of smoking and carotid and femoral artery IMT. Conclusions . Serum concentrations of CRP were related to insulin sensitivity and accompanying factors constituting the metabolic syndrome. The results indicate that this association may be mediated by adipose tissue and TNFalpha effects, the latter measured as the product of TNFalpha and sTNFAR2. This was a cross-sectional study and causality cannot be proven.

  • Do statins reduce the risk of myocardial infarction in patients with heart failure? A pooled individual-level reanalysis of CORONA and GISSI-HF

  • Ingår i: European Journal of Heart Failure. - : Wiley. - 1388-9842. ; 17:4, s. 434-441
  • Tidskriftsartikel (refereegranskat)abstract
    • AimsCurrent guidelines do not explicitly recommend statin use in heart failure (HF). Relatively low numbers of atherothrombotic events among HF patients, in the context of their elevated competing risks for non-atherothrombotic causes of death, may have prevented previous analyses of clinical trials from detecting a benefit for statins. We pooled data from two landmark trials of HF patients not on statin therapy randomized to rosuvastatin 10mg daily vs. placebo, CORONA and GISSI-HF, in order to improve our power to detect statistically significant differences in atherothrombotic events. We also accounted for competing risks from other causes of death. Methods and resultsWe used competing risks analyses to evaluate atherothrombotic events in the context of death from other cardiovascular and non-cardiovascular causes. We also performed traditional Cox survival analyses of the same data with the intention that these statistical approaches would be complementary. CORONA participants (n=5011, median follow-up 32.8months) were older and sicker than GISSI-HF participants (n=4574, median follow-up 46.9months) by design. Rosuvastatin decreased risk for myocardial infarction (MI) among CORONA and GISSI-HF participants with ischaemic aetiology of HF (hazard ratio 0.81, 95% confidence interval 0.66-0.99, P<0.05). There were no significant differences between rosuvastatin and placebo in risks for stroke or death from other causes. ConclusionThis individual-level reanalysis of two landmark trials demonstrates a small but statistically significant decreased risk for MI among patients with ischaemic HF randomized to rosuvastatin vs. placebo. Rosuvastatin appears to be effective in preventing MI in ischaemic HF patients not already on statins.

    • Background The incremental prognostic value of high-sensitive troponin T (hs-cTnT) in heart failure (HF) beyond that of high-sensitivity C-reactive protein and amino-terminal probrain natriuretic peptide is debated. We examined the prognostic value of hs-cTnT in a subgroup of patients from the Controlled Rosuvastatin Multinational Trial in HF (CORONA) study. Methods and Results Hs-cTnT as a risk factor for the primary end point (cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke; n=356), as well as all-cause mortality (n=366), cardiovascular mortality (n=299), and the composite of cardiovascular mortality and hospitalization from worsening of HF (n=465), was investigated in 1245 patients (60 years; New York Heart Association [NYHA] class II-IV, ischemic systolic HF) randomly assigned to 10 mg rosuvastatin or placebo. In multivariable analyses, adjusting for left ventricular ejection fraction, NYHA class, age, body mass index, diabetes mellitus, sex, intermittent claudication, heart rate, estimated glomerular filtration rate, apolipoprotein B/apolipoprotein A-1 ratio, amino-terminal probrain natriuretic peptide, high-sensitivity C-reactive protein, and hs-cTnT (both dichotomized according to the 99th percentile and as a continuous variable) was associated with all end points (primary end point: hazard ratio, 1.87 and 1.51, respectively, per SD change; P<0.001; all other end points: hazard ratio, 1.39-1.70). However, improved discrimination as assessed by C-statistics was only seen for the primary end point and all-cause mortality. Conclusions Elevated hs-cTnT levels provide strong and independent prognostic information in older patients with chronic ischemic HF. Clinical Trial Registration URL: http://www.clinicaltrials.gov.

    • To investigate whether plasma galectin-3, a mediator of fibrogenesis, can identify patients with chronic heart failure (HF) for whom statins are effective. Patients with ischaemic systolic HF enrolled in the Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA) were randomly assigned to 10 mg/day of rosuvastatin or placebo. Galectin-3 was measured in plasma. The primary outcome was cardiovascular death, myocardial infarction, or stroke. Of 1492 patients, 411 had a primary event during a median follow-up of 32.8 months. There was an interaction between baseline galectin-3 and rosuvastatin on the primary endpoint (P-value for interaction 0.036). Among patients with below the median plasma concentrations of galectin-3 (19.0 ng/mL), those assigned to rosuvastatin had a lower primary event rate [hazard ratio (HR) 0.65; 95 confidence interval (CI), 0.460.92; P 0.014], lower total mortality (HR 0.70; 95 CI, 0.500.98; P 0.038), and lower event rate of all-cause mortality and HF hospitalizations (HR 0.72; 95 CI, 0.540.98; P 0.017) compared with placebo, but no benefit was observed in patients with higher levels of galectin-3. The combination of concurrently low concentrations of galectin-3 and N-terminal pro-B-type natriuretic peptide (102.7 pmol/L) identified patients with a large benefit with rosuvastatin (HR 0.33; 95 CI, 0.160.67; P 0.002). Patients with systolic HF of ischaemic aetiology who have galectin-3 values 19.0 ng/mL may benefit from rosuvastatin treatment. However, the data from this post hoc analysis should be interpreted with caution since the overall results of the CORONA study did not show a significant effect on the primary endpoint.

    • Background Galectin-3 is a new biomarker involved in inflammation and fibrogenesis and could therefore contribute to myocardial remodeling. We examined the prognostic value of baseline galectin-3 in a substudy involving approximately 30% of participants in the CORONA study. Methods Patients (n = 1462) aged >60 years with systolic, ischemic heart failure (HF) were randomized to 10 mg/d rosuvastatin or placebo. The primary composite end point was cardiovascular death, nonfatal myocardial infarction, or stroke (n = 408). Results In the unadjusted analysis, galectin-3 was associated with all end points considered, except hospitalization for worsening of HF. In multivariable analyses, adjusting for other clinical and biochemical predictor variables, galectin-3 was significantly associated with the primary end point (hazard ratio [HR] 1.53 [1.10-2.12], P = .011) as well as all-cause (HR 1.61 [1.20-2.29], P = .002) and cardiovascular mortality (HR 1.70 [1.19-2.42], P = .003), sudden death (HR 1.83 [1.14-2.94], P = .012), and the coronary end point (HR 1.48 [1.03-2.12], P = .035). However, when N-terminal pro-brain natriuretic peptide was added to the model, galectin-3 association with the end points was markedly attenuated and no longer significant. Conclusions Galectin-3 is not associated with outcome in older patients with advanced chronic systolic HF of ischemic etiology when adjusting for N-terminal pro-brain natriuretic peptide and may therefore have limited use in the prognostication of elderly patients with systolic HF in clinical practice.

  • What resting heart rate should one aim for when treating patients with heart failure with a beta-blocker? Experiences from the Metoprolol Controlled Release/Extended Release Randomized Intervention Trial in Chronic Heart Failure (MERIT-HF)
  • 2005
  • Ingår i: J Am Coll Cardiol. - 0735-1097. ; 45:2, s. 252-9

    • OBJECTIVES: The goal of this study was to explore the question: what resting heart rate (HR) should one aim for when treating patients with heart failure with a beta-blocker? BACKGROUND: The interaction of pretreatment and achieved resting HR with the risk-reducing effect of beta-blocker treatment needs further evaluation. METHODS: Cardiovascular risk and risk reduction were analyzed in five subgroups defined by quintiles (Q) of pretreatment resting HR in the Metoprolol Controlled Release/Extended Release Randomized Intervention Trial in Chronic Heart Failure (MERIT-HF). RESULTS: Mean baseline HR in the 5 Qs were 71, 76, 81, 87, and 98 beats/min; achieved HR 63, 66, 68, 72, and 75 beats/min; and net change -8, -10, -11, -13, and -14 beats/min, respectively. Baseline HR was related to a number of baseline characteristics. Cardiovascular risk was no different in Q1 to Q4 (placebo groups) but increased in Q5 (HR above 90 beats/min). No relationship was observed between the risk-reducing effect of metoprolol controlled release/extended release (CR/XL) and baseline HR in the five Qs of baseline HR, or achieved HR, or change in HR during follow-up, respectively. CONCLUSIONS: Metoprolol CR/XL significantly reduced mortality and hospitalizations independent of resting baseline HR, achieved HR, and change in HR. Achieved HR and change in HR during follow-up were closely related to baseline HR; therefore, it was not possible to answer the question posed. Instead, one has to apply a very simple rule: aim for the target beta-blocker dose used in clinical trials, and strive for the highest tolerated dose in all patients with heart failure, regardless of baseline and achieved HR.

    • AimsLeucocyte telomere length is considered a marker of biological ageing and has been suggested to be shorter in patients with CAD and heart failure compared with healthy controls. The aim of this study was to determine whether telomere length is associated with clinical outcomes in patients with ischaemic heart failure and whether this association is superior to chronological age as defined by date of birth. Methods and resultsWe measured leucocyte telomere length in 3275 patients with chronic ischaemic systolic heart failure participating in the COntrolled ROsuvastatin multiNAtional Trial in Heart Failure (CORONA) study. The primary composite endpoint was cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke, which occurred in 575 patients during follow-up. We observed a significant association of leucocyte telomere lengths with the primary endpoint (hazard ratio 1.10; 95% confidence interval 1.01-1.20; P=0.03). However, this observation was not superior to age as defined by date of birth. The neutral effect of rosuvastatin treatment on clinical outcomes was not modified by baseline telomere length. ConclusionBiological age as defined by leucocyte telomere length was associated with clinical outcomes in patients with ischaemic heart failure, but this association did not add prognostic information above age as defined by date of birth.

  • The impact of coronary artery disease risk loci on ischemic heart failure severity and prognosis: association analysis in the COntrolled ROsuvastatin multiNAtional trial in heart failure (CORONA)

  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Recent genome-wide association studies have identified multiple loci that are associated with an increased risk of developing coronary artery disease (CAD). The impact of these loci on the disease severity and prognosis of ischemic heart failure due to CAD is currently unknown. Methods: We undertook association analysis of 7 single nucleotide polymorphism (rs599839, rs17465637, rs2972147, rs6922269, rs1333049, rs501120, and rs17228212) at 7 well established CAD risk loci (1p13.3, 1q41, 2q36.3, 6q25.1, 9p21.3, 10q11.21, and 15q22.33, respectively) in 3,320 subjects diagnosed with systolic heart failure of ischemic aetiology and participating in the COntrolled ROsuvastatin multiNAtional Trial in Heart Failure (CORONA) trial. The primary outcome was the composite of time to first event of cardiovascular death, non-fatal myocardial infarction and non-fatal stroke, secondary outcomes included mortality and hospitalization due to worsening heart failure. Results: None of the 7 loci were significantly associated with the primary composite endpoint of the CORONA trial (death from cardiovascular cases, nonfatal myocardial infarction, and nonfatal stroke). However, the 1p13.3 locus (rs599839) showed evidence for association with all-cause mortality (after adjustment for covariates; HR 0.74, 95% CI [0.61 to 0.90]; P = 0.0025) and we confirmed the 1p13.3 locus (rs599839) to be associated with lipid parameters (total cholesterol (P = 1.1x10(-4)), low-density lipoprotein levels (P = 3.5 x 10(-7)) and apolipoprotein B (P = 2.2 x 10(-10))). Conclusion: Genetic variants strongly associated with CAD risk are not associated with the severity and outcome of ischemic heart failure. The observed association of the 1p13.3 locus with all-cause mortality requires confirmation in further studies.

    • Abstract: The combination of heart failure and chronic obstructive pulmonary disease presents many therapeutic challenges. The cornerstones of therapy are beta-blockers and beta-agonists, respectively. Their pharmacological effects are diametrically opposed, and each is purported to adversely affect the alternative condition. The tolerability of beta-blockade in patients with mild and fixed airflow obstruction likely extends to those with more severe disease. However, the evidence is rudimentary. The long-term influence of beta-blockade on pulmonary function, symptoms, and quality of life is unclear. Low-dose initiation and gradual up-titration of cardioselective beta-blockers is currently recommended. Robust clinical trials are needed to provide the answers that may finally allay physicians' mistrust of beta-blockers in patients with chronic obstructive pulmonary disease. Beta-agonists are associated with incident heart failure in patients with pulmonary disease and with increased mortality and hospitalization in those with existing heart failure. These purported adverse effects require further investigation. In the meantime, clinicians should consider carefully the etiology of dyspnea and obtain objective evidence of airflow obstruction before prescribing beta-agonists to patients with heart failure.

    • OBJECTIVES To determine the efficacy and tolerability of beta blockers in a broad age range of women and men with heart failure with reduced ejection fraction (HFrEF) by pooling individual patient data from placebo controlled randomised trials. Prospectively designed meta-analysis of individual patient data from patients aged 40-85 in sinus rhythm at baseline, with left ventricular ejection fraction < 0.45. The primary outcome was all cause mortality; the major secondary outcome was admission to hospital for heart failure. Analysis was by intention to treat with an adjusted one stage Cox proportional hazards model. Compared with placebo, beta blockers were effective in reducing mortality across all ages: hazard ratios were 0.66 (95% confidence interval 0.53 to 0.83) for the first quarter of age distribution (median age 50); 0.71 (0.58 to 0.87) for the second quarter (median age 60); 0.65 (0.53 to 0.78) for the third quarter (median age 68); and 0.77 (0.64 to 0.92) for the fourth quarter (median age 75). There was no significant interaction when age was modelled continuously (P=0.1), and the absolute reduction in mortality was 4.3% over a median follow-up of 1.3 years (number needed to treat 23). Admission to hospital for heart failure was significantly reduced by beta blockers, although this effect was attenuated at older ages (interaction P=0.05). There was no evidence of an interaction between treatment effect and sex in any age group. Drug discontinuation was similar regardless of treatment allocation, age, or sex (14.4% in those give beta blockers, 15.6% in those receiving placebo). Irrespective of age or sex, patients with HFrEF in sinus rhythm should receive beta blockers to reduce the risk of death and admission to hospital.

    • BACKGROUND The relationship between mortality and heart rate remains unclear for patients with heart failure with reduced ejection fraction in either sinus rhythm or atrial fibrillation (AF). OBJECTIVES This analysis explored the prognostic importance of heart rate in patients with heart failure with reduced ejection fraction in randomized controlled trials comparing beta-blockers and placebo. METHODS The Beta-Blockers in Heart Failure Collaborative Group performed a meta-analysis of harmonized individual patient data from 11 double-blind randomized controlled trials. The primary outcome was all-cause mortality, analyzed with Cox proportional hazard ratios (HR) modeling heart rate measured at baseline and approximately 6 months post-randomization. RESULTS A higher heart rate at baseline was associated with greater all-cause mortality for patients in sinus rhythm (n = 14,166; adjusted HR: 1.11 per 10 beats/min; 95% confidence interval [CI]: 1.07 to 1.15; p < 0.0001) but not in AF (n = 3,034; HR: 1.03 per 10 beats/min; 95% CI: 0.97 to 1.08; p = 0.38). Beta-blockers reduced ventricular rate by 12 beats/min in both sinus rhythm and AF. Mortality was lower for patients in sinus rhythm randomized to beta-blockers (HR: 0.73 vs. placebo; 95% CI: 0.67 to 0.79; p < 0.001), regardless of baseline heart rate (interaction p = 0.35). Beta-blockers had no effect on mortality in patients with AF (HR: 0.96, 95% CI: 0.81 to 1.12; p = 0.58) at any heart rate (interaction p = 0.48). A lower achieved resting heart rate, irrespective of treatment, was associated with better prognosis only for patients in sinus rhythm (HR: 1.16 per 10 beats/min increase, 95% CI: 1.11 to 1.22; p < 0.0001). CONCLUSIONS Regardless of pre-treatment heart rate, beta-blockers reduce mortality in patients with heart failure with reduced ejection fraction in sinus rhythm. Achieving a lower heart rate is associated with better prognosis, but only for those in sinus rhythm. (C) 2017 by the American College of Cardiology Foundation.

  • Tidskriftsartikel (refereegranskat)abstract
    • AimsTo investigate the prognostic significance of hospitalization for worsening heart failure (WHF), myocardial infarction (MI), and stroke in patients with chronic heart failure (HF). Methods and resultsWe studied 5011 patients with HF and reduced EF (HF-REF) in the CORONA trial and 4128 patients with HF and preserved EF (HF-PEF) in the I-Preserve trial. Adjusted hazard ratios (HRs) for death were estimated for 0-30 days and 31 days after first post-randomization WHF, MI, or stroke used as a time-dependent variable, compared with patients with none of these events. In CORONA, 1616 patients (32%) had post-randomization first events (1223 WHF, 216 MI, 177 stroke), and the adjusted HR for mortality 30 days after an event was: WHF 7.21 [95% confidence interval (CI) 2.05-25.40], MI 23.08 (95% CI 6.44-82.71), and stroke 32.15 (95% CI 8.93-115.83). The HR for mortality at >30 days was: WHF 3.62 (95% CI 3.11-4.21), MI 4.41 (95% CI 3.23-6.02), and stroke 3.19 (95% CI 2.21-4.61). In I-Preserve, 896 patients (22%) experienced a post-randomization event (638 WHF, 111 MI, 147 stroke). The HR for mortality 30 days was WHF 31.77 (95% CI 7.60-132.81), MI 154.77 (95% CI 34.21-700.17), and stroke 223.30 (95% CI 51.42-969.78); for >30 days it was WHF 3.36 (95% CI 2.79-4.05), MI 3.29 (95% CI 2.14-5.06), and stroke 5.13 (95% CI 3.61-7.29). ConclusionsIn patients with both HF-REF and HF-PEF, hospitalization for WHF was associated with high early and late mortality. The early relative risk of death was not as great as following MI or stroke, but the longer term relative risk of death was similar following all three types of event. Numerically, more deaths occurred following WHF because it was a much more common event.

  • International Geographic Variation in Event Rates in Trials of Heart Failure With Preserved and Reduced Ejection Fraction
  • 2015
  • Ingår i: Circulation. - 1524-4539. ; 131, s. 43-53
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: -International geographic differences in outcomes may exist for clinical trials of heart failure and reduced ejection fraction (HF-REF), but there are few data for those with preserved ejection fraction (HF-PEF). METHODS AND RESULTS: -We analyzed outcomes by international geographic region in the Irbesartan in Heart Failure with Preserved systolic function trial (I-Preserve), the Candesartan in Heart failure Assessment of Reduction in Mortality and morbidity (CHARM)-Preserved trial, the CHARM-Alternative and CHARM-Added HF-REF trials, and the Controlled Rosuvastatin Multinational Trial in HF-REF (CORONA). Crude rates of heart failure hospitalization varied by geographic region, and more so for HF-PEF than for HF-REF. Rates in patients with HF-PEF were highest in the United States/Canada (HF hospitalization rate 7.6 per 100 patient-years in I-Preserve; 8.8 in CHARM-Preserved), intermediate in Western Europe (4.8/100 and 4.7/100), and lowest in Eastern Europe/Russia (3.3/100 and 2.8/100). The difference between the United States/Canada versus Eastern Europe/Russia persisted after adjustment for key prognostic variables: adjusted hazard ratios 1.34 (95% confidence interval, 1.01-1.74; P=0.04) in I-Preserve and 1.85 (95% confidence interval, 1.17-2.91; P=0.01) in CHARM-Preserved. In HF-REF, rates of HF hospitalization were slightly lower in Western Europe compared with other regions. For both HF-REF and HF-PEF, there were few regional differences in rates of all-cause or cardiovascular mortality. CONCLUSIONS: -The differences in event rates observed suggest there is international geographic variation in 1 or more of the definition and diagnosis of HF-PEF, the risk profile of patients enrolled, and the threshold for hospitalization, which has implications for the conduct of future global trials.

    • AIMS: Beta-blockers (BBs) confer significant prognostic benefit in patients (pts) with systolic chronic heart failure (CHF). However, major trials have thus far studied BBs mainly in addition to ACE-Inhibitors or angiotensin receptor blockers (ARBs) as background therapy. The magnitude of the prognostic benefit of BBs in the absence of ACE-I or ARB has not as yet been determined. METHODS AND RESULTS: We performed a meta-analysis of all placebo-controlled BB studies in patients with CHF (n>200). Trials were identified via Medline literature searches, meeting abstracts, and contact with study organizations. Results for all-cause mortality and death or heart failure hospitalization were pooled using the Mantel-Haenszel (fixed effects) method. The impact of BB therapy on all-cause mortality in CHF, in the absence (4.8%) and presence (95.2%) of ACE-I (or ARB), was determined from six trials of 13 370 patients. The risk ratio (RR) for BBs vs. placebo was 0.73 [95% confidence interval (CI) 0.53-1.02] in the absence of ACE-I or ARB at baseline, compared with a RR of 0.76 (95% CI 0.71-0.83) in the presence of these agents. When ACE-Inhibitors were analysed in the same way (pre-BB), a RR of 0.89 (0.80-0.99) vs. placebo was observed in studies of >90 days. The impact of BB therapy on death or HF hospitalization in systolic CHF, in the absence and presence of ACE-I, was determined from three trials of 8988 patients. The RR for BBs vs. placebo was 0.81 (95% CI 0.61-1.08) in the absence of ACE-I or ARB at baseline, compared with a RR of 0.78 (95% CI 0.74-0.83) in the presence of these agents. When ACE-Is were analysed in the same way (pre-BB), a RR of 0.85 (95% CI 0.78-0.93) vs. placebo was observed in studies of >90 days. CONCLUSION: The magnitude of the prognostic benefit conferred by BBs in the absence of ACE-I appears to be similar to those of ACE-Is in systolic CHF. These data therefore suggest that either ACE-Is or BBs could be used as first-line neurohormonal therapy in patients with systolic CHF. Prospective studies directly comparing these agents are required to definitively address this issue.

    • Pentraxin-3 (PTX3) is a component of the humoral arm of innate immunity which can regulate inflammatory processes. Since the role of inflammation in the progression of chronic heart failure (HF) is debated, we investigated the prognostic value of PTX3 and the effect of a statin in two large populations of patients with HF. Plasma levels of PTX3 were measured at randomization and after 3 months in 1457 patients enrolled in the Controlled Rosuvastatin Multinational Trial in HF (CORONA) and 1233 patients enrolled in the GISSI-Heart Failure trial (GISSI-HF). The relationships between baseline PTX3 levels or their changes over time and mortality were evaluated with multivariable Cox proportional hazard models including clinical factors, high sensitivity C-reactive protein (hsCRP), and N-terminal pro brain natriuretic peptide (NT-proBNP). PTX3 concentration [median (Q1Q3) 5.34 (3.557.64) ng/mL, n 2690] was higher in females, in older patients, and those with lower body mass index. Baseline elevated PTX3 was associated with a higher risk of all-cause mortality [759 events, hazard ratio (HR) for 1 SD increase 1.20, 95 confidence interval (CI) 1.121.30, P 0.0001], cardiovascular mortality (587 events, HR 1.27, 95 CI 1.171.38, P 0.0001), or hospitalization for worsening HF (720 events, HR 1.21, 95 CI 1.121.30, P 0.0001), and marginally improved discrimination. Three-month changes in PTX3 were associated with fatal events after adjustment for hsCRP or NT-proBNP. Rosuvastatin lowered hsCRP levels but significantly raised PTX3. In two independent clinical trials that enrolled patients with chronic HF, PTX3 was consistently associated with outcomes. The opposite effects of a statin on hsCRP and PTX3 call for further investigation. NCT00336336 (GISSI-HF), NCT00206310 (CORONA).

  • Tidskriftsartikel (refereegranskat)abstract
    • Aim We investigated the ability of prototypical inflammatory cytokines to predict clinical outcomes in a large population of patients with chronic systolic heart failure (HF). Methods and results Serum levels of tumour necrosis factor-alpha (TNF-alpha), soluble TNF receptors type I and II (sTNF-RI and sTNF-RII), and the chemokines monocyte chemoattractant protein-1 (MCP-1) and interleukin-8 (IL-8) were analysed in 1464 patients with chronic ischaemic systolic HF in the CORONA study, aged >= 60 years, in NYHA class II-IV, and related to the primary endpoint (n = 320), as well as any coronary event (n = 255), all-cause mortality (n = 329), cardiovascular (CV) mortality (n = 268), and the composite endpoint hospitalization from worsening heart failure (WHF) or CV mortality (n = 547). TNF-alpha, sTNF-RI, sTNF-RII, and IL-8, but not MCP-1, were independent predictors of all endpoints except the coronary endpoint in multivariable models including conventional clinical variables. After further adjustment for estimated glomerular filtration rate, the ApoB/ApoA-1 ratio, NT-proBNP, and high-sensitivity C-reactive protein, only IL-8 remained a significant predictor of all endpoints (except the coronary endpoint), while sTNF-RI remained independently associated with CV mortality. Adding IL-8 to the full model led to a significant improvement in net reclassification for all-cause mortality and CV hospitalization, but only a borderline significant improvement for the primary endpoint, CV mortality, and the composite endpoint WHF hospitalization or CV mortality. Conclusion Our study supports a relationship between IL-8 and outcomes in patients with chronic HF. However, the clinical usefulness of IL-8 as a biomarker in an unselected HF population is at present unclear.

    • Objective. To study the prognostic value of neutrophil gelatinase-associated lipocalin (NGAL) in chronic heart failure (HF) of ischaemic aetiology. Background. Neutrophil gelatinase-associated lipocalin is a marker of kidney injury as well as matrix degradation and inflammation and has previously been shown to be increased in HF. We investigated whether serum NGAL levels could provide prognostic information in chronic HF. Methods. We assessed NGAL as a predictor of primary outcomes (cardiovascular death, nonfatal stroke and nonfatal myocardial infarction, n=307) and all-cause mortality (n=321), cardiovascular mortality (n=259) and hospitalization (n=647) as well as the number of hospitalizations during follow-up for all (n=1934) and CV causes (n=1204) in 1415 patients with chronic HF (≥60years, New York Heart Association class II-IV, ischaemic systolic HF) in the CORONA population, randomly assigned to 10mg rosuvastatin or placebo. Results. Multivariate analysis revealed that NGAL added significant information when adjusting for clinical variables, but was no longer significant when further adjusting for apolipoprotein A-1 (ApoA-1), glomerular filtration rate (GFR), C-reactive protein (CRP) and N-terminal pro-brain natriuretic peptide (NT-proBNP). However, belonging to the highest NGAL tertile was associated with more frequent hospitalization, even after adjusting for clinical variables, GFR and ApoA-1, but not after adjusting for CRP and NT-proBNP. There was no interaction between rosuvastatin treatment and NGAL. Conclusion. Neutrophil gelatinase-associated lipocalin added no significant information to NT-proBNP and GFR in a multivariate model for primary and secondary end-points. © 2012 The Association for the Publication of the Journal of Internal Medicine.

    • Objectives: This study sought to examine the association between thyroid status and clinical outcomes in patients in the CORONA (Controlled Rosuvastatin Multinational Trial in Heart Failure) study. Background: Hypo- and hyperthyroidism were associated with worse clinical outcomes in the SCD-HeFT (Sudden Cardiac DeathinHeart Failure Trial). Methods: In CORONA, 4,987 patients underwent baseline thyroid-stimulating hormone (TSH) measurement, 237 of which(4.8%) were receiving thyroid replacement therapy (TRT). Patients were classified as euthyroid (TSH: 0.3 to 5.0μU/ml,and no TRT), hyperthyroid (<0.3 μU/ml and no TRT), or hypothyroid (>5.0 μU/ml and no TRT). The outcome composites of cardiovascular (CV) death or hospitalization for heart failure (HF), the components of this composite, and all-cause death were compared among hyperthyroid, hypothyroid, and euthyroid states, using multivariable models adjusting for previously reported prognostic variables. Results: A total of 91.3% of patients were euthyroid, 5.0% were hypothyroid, and 3.7% were hyperthyroid. Compared with euthyroid patients, hypothyroid patients were more likely to have a history of stroke, had worse renal function andhigher N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels, were more likely to be treated with an antiarrhythmic drug (or have an implantable cardioverter defibrillator), and were less likely to smoke or be treated with a beta-blocker or angiotensin-converting enzyme inhibitor/angiotensin receptor blocker. In univariate analyses, hypothyroidism was associated with an increased risk of the composite outcome of CV death or HF hospitalization (hazard ratio: 1.29; 95% confidence interval: 1.07 to 1.57; p= 0.008), as well as all-cause death (HR: 1.36; 95% confidence interval: 1.03 to 1.76; p= 0.004). However, after adjustment for other known predictors of outcome, the associations were weakened, and when NT-proBNP was added to the models, the association between hypothyroidism and all outcomes was eliminated. Conclusions: Thyroid status is not an independent predictor of outcome in heart failure with reduced ejection fraction.

    • Objectives: The purpose of this study was to examine the relationship between fatigue and clinical outcomes, using dyspnea as a comparator, in patients with left ventricular ejection fraction (LVEF)≤35% enrolled in the CORONA (Controlled Rosuvastatin Multinational Trial in Heart Failure) study. Background: Although fatigue is a common symptom in heart failure (HF), little is known about its association with prognosis. Methods: At baseline in CORONA, fatigue "during the past few days" was measured using a 5-point exertion scale (0= none, 1= heavy exertion, 2= moderate exertion, 3= slight exertion, 4= rest); a 4-point scale was used for dyspnea (1to4 as for fatigue). Patients were grouped into 3 categories: a fatigue score 0 to 1 (n= 535), fatigue score 2(n=1,632), and fatigue score 3 to 4 (n= 1,663); and a dyspnea score of 1 (n= 292), dyspnea score of 2(n=1,695), and dyspnea score of 3 to 4 (n= 1,843). The association between fatigue and dyspnea and the composite outcome of cardiovascular (CV) death or HF hospital stay and each component separately was examined using Kaplan-Meier analysis and Cox proportional-hazard models. We also examined all-cause mortality. Results: In univariate analyses, symptom severity was associated with a higher risk of CV death or HF hospital stay (fatigue: group 3, 49% [n= 810], vs. group 1, 30% [n= 160]; dyspnea: group 3, 50% [n= 918], vs. group 1, 28% [n= 82]) and all-cause mortality (fatigue: group 3, 38% [n= 623], vs. group 1, 24% [n= 130]; dyspnea: group 3, 38% [n=697], vs. group 1, 23% [n= 66], log-rank p< 0.0001 for all). After adjusting for other prognostic variables, including LVEF, New York Heart Association class, and N-terminal pro-B-type natriuretic peptide level, worse fatigue remained associated with higher risk of HF hospital stay but not mortality (worse dyspnea remained associated with a higher risk of both). An increase in fatigue (or dyspnea) between baseline and 6 months was also associated with worse outcomes. Conclusions: In HF, greater fatigue is associated with worse clinical outcomes. Closer attention should be paid to this symptom in clinical practice, with more done to standardize its measurement and understand its origins, with a view to improving treatment. © 2014 American College of Cardiology Foundation.

  • Slightly elevated high-sensitivity C-reactive protein (hsCRP) concentrations are associated with carotid atherosclerosis in women with varying degrees of glucose tolerance.
  • 2010
  • Ingår i: Angiology. - : SAGE Publications. - 1940-1574 .- 0003-3197. ; 61:8, s. 793-801

    • We examined whether high-sensitivity C-reactive protein (hsCRP) ≥2.0 mg/L was associated with increased intima-media thickness (IMT), plaque burden, and plaque echolucency in carotid arteries. Women (n = 635) from a population sample of 64-year-old females with varying degrees of glucose tolerance underwent risk factor assessment, measurement of hsCRP, and ultrasound examinations of the carotid arteries. Participants with hsCRP levels ≥2.0 mg/L had elevated carotid bulb IMT independently of other cardiovascular risk factors compared with those with hsCRP <2.0 mg/L. The participants with plaques in the highhsCRP group had larger total plaque area compared to those with plaque in the lower hsCRP group. Plaque echolucency did not differ between groups. High-sensitivity CRP levels ≥2.0 mg/L were accompanied by elevated IMT in the carotid bulbs independently of other cardiovascular risk factors. Total plaque area was larger among women with plaques in the high hsCRP group versus the lower hsCRP group.

  • Effect of Statins on Venous Thromboembolic Events: A Meta-analysis of Published and Unpublished Evidence from Randomised Controlled Trials
  • 2012
  • Ingår i: Plos Medicine. - : Public Library of Science (PLoS). - 1549-1676. ; 9:9
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: It has been suggested that statins substantially reduce the risk of venous thromboembolic events. We sought to test this hypothesis by performing a meta-analysis of both published and unpublished results from randomised trials of statins. Methods and Findings: We searched MEDLINE, EMBASE, and Cochrane CENTRAL up to March 2012 for randomised controlled trials comparing statin with no statin, or comparing high dose versus standard dose statin, with 100 or more randomised participants and at least 6 months' follow-up. Investigators were contacted for unpublished information about venous thromboembolic events during follow-up. Twenty-two trials of statin versus control (105,759 participants) and seven trials of an intensive versus a standard dose statin regimen (40,594 participants) were included. In trials of statin versus control, allocation to statin therapy did not significantly reduce the risk of venous thromboembolic events (465 [0.9%] statin versus 521 [1.0%] control, odds ratio [OR] = 0.89, 95% CI 0.78-1.01, p = 0.08) with no evidence of heterogeneity between effects on deep vein thrombosis (266 versus 311, OR 0.85, 95% CI 0.72-1.01) and effects on pulmonary embolism (205 versus 222, OR 0.92, 95% CI 0.76-1.12). Exclusion of the trial result that provided the motivation for our meta-analysis (JUPITER) had little impact on the findings for venous thromboembolic events (431 [0.9%] versus 461 [1.0%], OR = 0.93 [95% CI 0.82-1.07], p = 0.32 among the other 21 trials). There was no evidence that higher dose statin therapy reduced the risk of venous thromboembolic events compared with standard dose statin therapy (198 [1.0%] versus 202 [1.0%], OR = 0.98, 95% CI 0.80-1.20, p = 0.87). Risk of bias overall was small but a certain degree of effect underestimation due to random error cannot be ruled out. Conclusions: The findings from this meta-analysis do not support the previous suggestion of a large protective effect of statins (or higher dose statins) on venous thromboembolic events. However, a more moderate reduction in risk up to about one-fifth cannot be ruled out. Please see later in the article for the Editors' Summary.

  • Effect of rosuvastatin on repeat heart failure hospitalizations: The CORONA trial (controlled rosuvastatin multinational trial in heart failure)
  • 2014
  • Ingår i: JACC: Heart Failure. - : Elsevier Inc.. - 2213-1787 .- 2213-1779. ; 2:3, s. 289-297
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: This study sought to examine the effect of statin therapy hospitalizations for heart failure (HFH) in patients in the CORONA (Controlled Rosuvastatin Multinational Trial in Heart Failure) trial. Background: HFH is an important, frequently recurrent event. Conventional time-to-first event analyses do not take account repeat events. We used a number of statistical approaches to examine the effect of treatment on first and repeat HFH in the CORONA trial. Methods: In the CORONA trial, 5,011 patients ≥60 years of age with chronic New York Heart Association functional classes II to IV systolic heart failure resulting from ischemia were randomized to receive rosuvastatin or placebo. Poisson, Andersen-Gill, and negative binomial methods (NB) were used to analyze the effect of rosuvastatin on HFH, and the NB and a parametric joint frailty model (JF) were used to examine this effect while accounting for the competing risk of cardiovascular (CV) death. Rosuvastatin/placebo rate ratios were calculated, both unadjusted and adjusted. Results: A total of 1,291 patients had 1 or more HFH (750 of these had a single HFH only), and there were a total of 2,408 HFHs. The hazard ratio for the conventional time-to-first event analysis for HFH was 0.91 (95% confidence interval [CI]: 0.82 to 1.02, p = 0.105). In contrast, the NB on repeat hospitalizations gave an unadjusted RR (RR) for HFH of 0.86 (95% CI: 0.75 to 0.99, p = 0.030), adjusted 0.82 (95% CI: 0.72 to 0.92, p = 0.001), and after including CV death as the last event, adjusted RR of 0.85 (95% CI: 0.77 to 0.94, p = 0.001). The JF gave an adjusted RR of 0.82 (95% CI: 0.73 to 0.92, p = 0.001). Similar results were found in analyses of all CV hospitalizations and all-cause hospitalizations. Conclusions: When repeat events were included, rosuvastatin was shown to reduce the risk of HFH by approximately 15% to 20%, equating to approximately 76 fewer admissions per 1,000 patients treated over a median 33 months of follow-up. Including repeat events could increase the ability to detect treatment effects in heart failure trials. © 2014 American College of Cardiology Foundation.

  • apoB/apoA-I ratio is related to femoral artery plaques and is predictive for future cardiovascular events in healthy men
  • 2006
  • Ingår i: Atherosclerosis. - : Elsevier BV. - 0021-9150. ; 189:1, s. 178-85
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: The aim of the present study was to investigate the association between serum concentrations of apoB, apoA-I and the apoB/apoA-I ratio and future cardiovascular events in a group of healthy 58-year-old men during 6.6 years of follow-up. A further aim was to investigate the concentrations of apoB, apoA-I and the apoB/apoA-I ratio to the association of plaque occurrence in the carotid and femoral arteries. BACKGROUND: Previous studies have shown that the apoB/apoA-I ratio is an important cardiovascular risk factor, whereas the association between apoB/apoA-I ratio and presence of atherosclerotic plaques in the carotid and femoral arteries has been less investigated. METHODS: The carotid and femoral arteries were examined by high-resolution B-mode ultrasound in 391, 58-year-old men identified by screening in the city of Goteborg, Sweden. Assessment of plaque occurrence and measurement of apolipoproteins (apoA-I and apoB) was performed. RESULTS: Subjects with an apoB/apoA-I ratio >/=0.9 had a significantly increased risk to suffer a cardiovascular event during 6.6 years of follow-up (OR 3.07, 95% CI 1.22-7.71), while no difference in risk for cardiovascular events was observed for subjects with LDL cholesterol >3.4 mmol/L compared to subjects <3.4 mmol/L (OR 1.04, 95% CI 0.37-2.46). A greater risk for plaques in the femoral artery was also observed in subjects with an apoB/apoA-I ratio >/=0.9 compared to subjects <0.9 (OR 3.06, 95% CI 1.22-7.70). In a multiple logistic regression model, both elevated apoB/apoA-I ratio and plaque occurrence in the femoral artery were of significant importance for cardiovascular events during follow-up. CONCLUSIONS: The results showed that the apoB/apoA-I ratio was associated with arteriosclerosis in the femoral artery, and predicted future cardiovascular events. These observations, and the fact that apoB and apoA-I can be measured in the non-fasting state with high precision, in combination with the finding that LDL cholesterol did not predict cardiovascular disease, support results from other studies that the apoB/apoA-I ratio may be a superior risk marker for cardiovascular disease.

  • Chlamydia pneumoniae seropositivity is associated with carotid artery intima-media thickness
  • 2000
  • Ingår i: Stroke. - 0039-2499 .- 1524-4628. ; 31:7, s. 1526-1531
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND AND PURPOSE: Infection may both augment the atherosclerotic process and contribute to later manifestations of overt clinical disease. Chlamydia pneumoniae elementary bodies have been detected in atherosclerotic lesions. The aim of the present study was to investigate whether elevated titers of antibodies and circulating immune complexes to C pneumoniae were associated with ultrasound findings indicating presence of atherosclerosis in the carotid artery. METHODS: Serum titers of antibodies to C pneumoniae (IgM, IgA, IgG, and circulating immune complex) were related to intima-media thickness (IMT) and plaque status measured by B-mode ultrasound in the carotid artery in 113 men with treated hypertension and at least 1 of the following risk factors: hypercholesterolemia, smoking, or diabetes. RESULTS: Any of the titers was elevated in 56 (50%) men, and common carotid artery IMT was thicker in this group compared with the 57 men without any elevated titers (1.00 versus 0.92 mm, P<0.05). There were no accompanying differences in blood pressure, lipid levels, blood glucose, or smoking. Elevation of separate antibody types and circulation immune complex were also associated with increased IMT. In the latter group, systolic blood pressure was higher among seropositive patients compared with those who had no circulating immune complex. Seropositivity was not related to plaque status. CONCLUSIONS: Seropositivity for C pneumoniae was associated with an increased intima-media thickness in the common carotid artery but not plaque status in hypertensive men at high risk for cardiovascular disease.

  • High apoB/apoA-I ratio is associated with increased progression rate of carotid artery intima-media thickness in clinically healthy 58-year-old men: Experiences from very long-term follow-up in the AIR study
  • 2009
  • Ingår i: Atherosclerosis. ; :205, s. 284-289
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: The aim of the present study was to investigate the relationship between atherosclerotic progression rate as measured by carotid artery IMT during very long-term follow-up in clinically healthy men and a number of baseline risk factors of potential importance for atherosclerosis progression including apoA-I, apoB, apoB/apoA-I ratio, other lipid variables including LDL particle size, body composition variables, blood pressure, smoking, fasting blood glucose and insulin, and also hsCRP. BACKGROUND: Low-density lipoprotein (LDL) is associated with increased carotid IMT progression rate during long-term follow-up, whereas the relationship between newer biomarkers such as apoB/apoA-I ratio and carotid artery IMT progression rate has been less investigated. METHODS: 58-year-old men identified by screening in the community (n=391) with varying degrees of obesity and insulin sensitivity were examined with high-resolution B-mode ultrasound at baseline and after 3, and 8.9 years of follow-up (n=305 investigated after 8.9 years). The carotid arteries were examined bilaterally, and the mean intima-thickness was calculated for 10mm sections of the composite of common carotid arteries and bulbs (IMT(composite)). Serum levels of apoB and apoA-I were measured using a turbidimetric method. Uni- and multi-variable analyses were performed to study the relationship between carotid IMT(composite) progression rate and risk factors. RESULTS: In a multi-variable analysis including all baseline variables only the apoB/apoA-I ratio (p=0.003; beta=0.181, standard error=0.003) and serum insulin (p=0.026; beta=-0.133, standard error=0.000) was significantly related to IMT(composite) progression rate. CONCLUSION: The results indicate that apoB/apoA-I ratio is an important risk factor for predicting atherosclerotic progression rate during very long-term follow-up in clinically healthy middle-aged men.
