    • 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%.

  • Treatment with insulin is associated with worse outcome in patients with chronic heart failure and diabetes
  • 2018
  • Ingår i: European Journal of Heart Failure. - : Wiley. - 1388-9842. ; 20:5, s. 888-895
  • 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.

  • 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.

  • Telomere length and outcomes in ischaemic heart failure: data from the COntrolled ROsuvastatin multiNAtional Trial in Heart Failure (CORONA)
  • 2015
  • Ingår i: European Journal of Heart Failure. - : Wiley. - 1388-9842. ; 17:3, s. 313-319
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Thyroid-Stimulating Hormone and Clinical Outcomes: The CORONA Trial (Controlled Rosuvastatin Multinational Study in Heart Failure)
  • 2014
  • Ingår i: JACC: Heart Failure. - : Elsevier BV. - 2213-1779. ; 2:1, s. 35-40
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Fatigue as a predictor of outcome in patients with heart failure. Analysis of CORONA (Controlled rosuvastatin multinational trial in heart failure)
  • 2014
  • Ingår i: JACC: Heart Failure. - : Elsevier BV. - 2213-1779. ; 2:2, s. 187-197
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Relationship between angina pectoris and outcomes in patients with heart failure and reduced ejection fraction: an analysis of the Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA)
  • 2014
  • Ingår i: European Heart Journal. - : Oxford University Press (OUP). - 0195-668X .- 1522-9645. ; 35:48, s. 3426-3433
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • 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.

  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES The authors investigated the relationship between past or incident myocardial infarction (MI) and car-diovascular (CV) events in heart failure with preserved ejection fraction (HFpEF). BACKGROUND MI and HFpEF share some common risk factors. The prognostic significance of MI in patients with HFpEF is uncertain. METHODS The authors pooled data from 3 trials-CHARM Preserved (Candesartan Cilexietil in Heart Failure Assessment of Reduction in Mortality and Morbidity), I-Preserve (Irbesartan in Heart Failure With Preserved Systolic Function), and the Americas region of TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist) (N 1/4 8,916)-and examined whether MI before or following enrollment independently predicted CV death and heart failure (HF) hospitalization. RESULTS At baseline, 2,668 patients (30%) had history of MI. Prior MI was independently associated with greater risk of CV death (4.7 vs. 3.5 events/100 patient-years [py], adjusted hazard ratio [HR]: 1.42 [95% confidence interval (CI): 1.23 to 1.64]; p < 0.001). Excess sudden death drove this difference (1.9 vs. 1.2 events/100 py, adjusted HR: 1.55 [95% CI: 1.23 to 1.97]; p < 0.001). There was no difference in HF hospitalization (5.9 vs. 5.5 events/100 py, adjusted HR: 1.05, 95% CI: 0.92 to 1.19) or HF death by prior MI. During follow-up, MI occurred in 336 patients (3.8%). Risk of CV death increased 31-fold in the first 30 days after first post-enrollment MI, and remained 58% higher beyond 1 year after MI. Risk of first or recurrent HF hospitalization increased 2.4-fold after MI. CONCLUSIONS Prior MI in HFpEF is associated with greater CV and sudden death but similar risk of HF outcomes. Patients with HFpEF who experience MI are at high risk of subsequent CV death and HF hospitalization. These data highlight the importance of primary and secondary prevention of MI in patients with HFpEF.

  • Apixaban versus Warfarin in Patients with Atrial Fibrillation
  • 2011
  • Ingår i: New England Journal of Medicine. - 0028-4793 .- 1533-4406. ; 365:11, s. 981-992

    • Background Vitamin K antagonists are highly effective in preventing stroke in patients with atrial fibrillation but have several limitations. Apixaban is a novel oral direct factor Xa inhibitor that has been shown to reduce the risk of stroke in a similar population in comparison with aspirin. Methods In this randomized, double-blind trial, we compared apixaban (at a dose of 5 mg twice daily) with warfarin (target international normalized ratio, 2.0 to 3.0) in 18,201 patients with atrial fibrillation and at least one additional risk factor for stroke. The primary outcome was ischemic or hemorrhagic stroke or systemic embolism. The trial was designed to test for noninferiority, with key secondary objectives of testing for superiority with respect to the primary outcome and to the rates of major bleeding and death from any cause. Results The median duration of follow-up was 1.8 years. The rate of the primary outcome was 1.27% per year in the apixaban group, as compared with 1.60% per year in the warfarin group (hazard ratio with apixaban, 0.79; 95% confidence interval [CI], 0.66 to 0.95; P<0.001 for noninferiority; P=0.01 for superiority). The rate of major bleeding was 2.13% per year in the apixaban group, as compared with 3.09% per year in the warfarin group (hazard ratio, 0.69; 95% CI, 0.60 to 0.80; P<0.001), and the rates of death from any cause were 3.52% and 3.94%, respectively (hazard ratio, 0.89; 95% CI, 0.80 to 0.99; P=0.047). The rate of hemorrhagic stroke was 0.24% per year in the apixaban group, as compared with 0.47% per year in the warfarin group (hazard ratio, 0.51; 95% CI, 0.35 to 0.75; P<0.001), and the rate of ischemic or uncertain type of stroke was 0.97% per year in the apixaban group and 1.05% per year in the warfarin group (hazard ratio, 0.92; 95% CI, 0.74 to 1.13; P=0.42). Conclusions In patients with atrial fibrillation, apixaban was superior to warfarin in preventing stroke or systemic embolism, caused less bleeding, and resulted in lower mortality.

  • Galectin-3 predicts response to statin therapy in the Controlled Rosuvastatin Multinational Trial in Heart Failure (CORONA)
  • 2012
  • Ingår i: European Heart Journal. - : Oxford University Press (OUP). - 0195-668X .- 1522-9645. ; 33:18, s. 2290-2296

    • 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.

  • 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.)

    • Atrial fibrillation (AF) is associated with increased risk of stroke that can be attenuated with vitamin K antagonists (VKAs). Vitamin K antagonist use is limited, in part, by the high incidence of complications when patients' international normalized ratios (INRs) deviate from the target range. The primary objective of ARISTOTLE is to determine if the factor Xa inhibitor, apixaban, is noninferior to warfarin at reducing the combined endpoint of stroke (ischemic or hemorrhagic) and systemic embolism in patients with AF and at least 1 additional risk factor for stroke. We have randomized 18,206 patients from over 1,000 centers in 40 countries. Patients were randomly assigned in a 1:1 ratio to receive apixaban or warfarin using a double-blind, double-dummy design. International normalized ratios are monitored and warfarin (or placebo) is adjusted aiming for a target INR range of 2 to 3 using a blinded, encrypted point-of-care device. Minimum treatment is 12 months, and maximum expected exposure is 4 years. Time to accrual of at least 448 primary efficacy events will determine treatment duration. The key secondary objectives are to determine if apixaban is superior to warfarin for the combined endpoint of stroke (ischemic or hemorrhagic) and systemic embolism, and for all-cause death. These will be tested after the primary objective using a closed test procedure. The noninferiority boundary is 1.38; apixaban will be declared noninferior if the 95% CI excludes the possibility that the primary outcome rate with apixaban is >1.38 times higher than with warfarin. ARISTOTLE will determine whether apixaban is noninferior or superior to warfarin in preventing stroke and systemic embolism; whether apixaban has particular benefits in the warfarin-naive population; whether it reduces the combined rate of stroke, systemic embolism, and death; and whether it impacts bleeding.

  • Efficacy and safety of apixaban compared with warfarin according to patient risk of stroke and of bleeding in atrial fibrillation : a secondary analysis of a randomised controlled trial
  • 2012
  • Ingår i: The Lancet. - 0140-6736 .- 1474-547X. ; 380:9855, s. 1749-1758

    • Background The Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial showed that apixaban is better than warfarin at prevention of stroke or systemic embolism, causes less bleeding, and results in lower mortality. We assessed in this trial's participants how results differed according to patients' CHADS(2), CHA(2)DS(2)VASc, and HAS-BLED scores, used to predict the risk of stroke and bleeding. Methods ARISTOTLE was a double-blind, randomised trial that enrolled 18 201 patients with atrial fibrillation in 39 countries. Patients were randomly assigned apixaban 5 mg twice daily (n=9120) or warfarin (target international normalised ratio 2.0-3.0; n=9081). The primary endpoint was stroke or systemic embolism. The primary safety outcome was major bleeding. We calculated CHADS(2), CHA(2)DS(2)VASc, and HAS-BLED scores of patients at randomisation. Efficacy analyses were by intention to treat, and safety analyses were of the population who received the study drug. ARISTOTLE is registered with ClinicalTrials.gov, number NCT00412984. Findings Apixaban significantly reduced stroke or systemic embolism with no evidence of a differential effect by risk of stroke (CHADS(2) 1, 2, or >= 3, p for interaction=0.4457; or CHA(2)DS(2)VASc 1, 2, or >= 3, p for interaction=0.1210) or bleeding (HAS-BLED 0-1, 2, or >= 3, p for interaction=0.9422). Patients who received apixaban had lower rates of major bleeding than did those who received warfarin, with no difference across all score categories (CHADS(2), p for interaction=0.4018; CHA(2)DS(2)VASc, p for interaction=0.2059; HAS-BLED, p for interaction=0.7127). The relative risk reduction in intracranial bleeding tended to be greater in patients with HAS-BLED scores of 3 or higher (hazard ratio [HR] 0.22, 95% CI 0.10-0.48) than in those with HAS-BLED scores of 0-1 (HR 0.66, 0.39-1.12; p for interaction=0.0604). Interpretation Because apixaban has benefits over warfarin that are consistent across patient risk of stroke and bleeding as assessed by the CHADS(2), CHA(2)DS(2)VASc, and HAS-BLED scores, these scores might be less relevant when used to tailor apixaban treatment to individual patients than they are for warfarin. Further improvement in risk stratification for both stroke and bleeding is needed, particularly for patients with atrial fibrillation at low risk for these events.

  • Declining Risk of Sudden Death in Heart Failure
  • 2017
  • Ingår i: New England Journal of Medicine. - 0028-4793. ; 377:1, s. 41-51
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND The risk of sudden death has changed over time among patients with symptomatic heart failure and reduced ejection fraction with the sequential introduction of medications including angiotensin-converting-enzyme inhibitors, angiotensin-receptor blockers, beta-blockers, and mineralocorticoid-receptor antagonists. We sought to examine this trend in detail. We analyzed data from 40,195 patients who had heart failure with reduced ejection fraction and were enrolled in any of 12 clinical trials spanning the period from 1995 through 2014. Patients who had an implantable cardioverter-defibrillator at the time of trial enrollment were excluded. Weighted multivariable regression was used to examine trends in rates of sudden death over time. Adjusted hazard ratios for sudden death in each trial group were calculated with the use of Cox regression models. The cumulative incidence rates of sudden death were assessed at different time points after randomization and according to the length of time between the diagnosis of heart failure and randomization. Sudden death was reported in 3583 patients. Such patients were older and were more often male, with an ischemic cause of heart failure and worse cardiac function, than those in whom sudden death did not occur. There was a 44% decline in the rate of sudden death across the trials (P = 0.03). The cumulative incidence of sudden death at 90 days after randomization was 2.4% in the earliest trial and 1.0% in the most recent trial. The rate of sudden death was not higher among patients with a recent diagnosis of heart failure than among those with a longer-standing diagnosis. Rates of sudden death declined substantially over time among ambulatory patients with heart failure with reduced ejection fraction who were enrolled in clinical trials, a finding that is consistent with a cumulative benefit of evidence-based medications on this cause of death.

  • Biomarkers and heart failure events in patients with atrial fibrillation in the ARISTOTLE trial evaluated by a multi-state model
  • 2022
  • Ingår i: American Heart Journal. - : Elsevier. - 0002-8703 .- 1097-6744. ; 251, s. 13-24
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundAtrial fibrillation (AF) and heart failure (HF) often coexist. We investigated the prognostic impact of biomarkers on the development of HF and death in patients with AF and different left ventricular systolic function considering the influence of competing events.MethodsThe study included 11,818 patients with AF from the ARISTOTLE trial who at entry had information on history of HF, an estimate of left ventricular function and plasma samples for determination of biomarkers representing cardiorenal dysfunction (NT-proBNP, troponin T, cystatin C) and inflammation (GDF-15, IL-6, CRP). Patients were categorized into: (I) HF with reduced ejection fraction (HFrEF, n = 2,048), (II) HF with preserved ejection fraction (HFpEF, n = 2,520), and (III) No HF (n = 7,250). Biomarker associations with HF hospitalization and death were analyzed using a multi-state model accounting also for repeated events.ResultsBaseline levels of NT-proBNP, troponin T, cystatin C, GDF-15, IL-6, and CRP were highest in HFrEF and lowest in No HF. During median 1.9 years follow-up, 546 patients were hospitalized at least once for HF and 819 died. Higher levels of all investigated biomarkers were associated with both outcomes (all P < .0001), with highest event rates in HFrEF and lowest in No HF. The associations remained after adjustments and were more pronounced for first than for recurrent events.ConclusionsIn anticoagulated patients with AF, biomarkers indicating cardiorenal dysfunction and inflammation improve the identification of patients at risk of developing HF or worsening of already existing HF. These biomarkers might be useful for targeting novel HF therapies in patients with AF.

  • Assessing and grading congestion in acute heart failure : a scientific statement from the acute heart failure committee of the heart failure association of the European Society of Cardiology and endorsed by the European Society of Intensive Care Medicine.
  • 2010
  • Ingår i: European Journal of Heart Failure. - : Wiley. - 1388-9842 .- 1879-0844. ; 12:5, s. 423-33

    • Patients with acute heart failure (AHF) require urgent in-hospital treatment for relief of symptoms. The main reason for hospitalization is congestion, rather than low cardiac output. Although congestion is associated with a poor prognosis, many patients are discharged with persistent signs and symptoms of congestion and/or a high left ventricular filling pressure. Available data suggest that a pre-discharge clinical assessment of congestion is often not performed, and even when it is performed, it is not done systematically because no method to assess congestion prior to discharge has been validated. Grading congestion would be helpful for initiating and following response to therapy. We have reviewed a variety of strategies to assess congestion which should be considered in the care of patients admitted with HF. We propose a combination of available measurements of congestion. Key elements in the measurement of congestion include bedside assessment, laboratory analysis, and dynamic manoeuvres. These strategies expand by suggesting a routine assessment of congestion and a pre-discharge scoring system. A point system is used to quantify the degree of congestion. This score offers a new instrument to direct both current and investigational therapies designed to optimize volume status during and after hospitalization. In conclusion, this document reviews the available methods of evaluating congestion, provides suggestions on how to properly perform these measurements, and proposes a method to quantify the amount of congestion present.

    • 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.

    • Background High-sensitivity troponin-I (hs-TnI) measurement improves risk assessment for cardiovascular events in many clinical settings, but the added value in atrial fibrillation patients has not been described. Methods and Results At randomization, hs-TnI was analyzed in 14 821 atrial fibrillation patients in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial comparing apixaban with warfarin. The associations between hs-TnI concentrations and clinical outcomes were evaluated by using adjusted Cox analysis. The hs-TnI assay detected troponin (1.3 ng/L) in 98.5% patients, 50% had levels >5.4, 25% had levels >10.1, and 9.2% had levels 23 ng/L (the 99th percentile in healthy individuals). During a median of 1.9 years follow-up, annual rates of stroke or systemic embolism ranged from 0.76% in the lowest hs-TnI quartile to 2.26% in the highest quartile (>10.1 ng/L). In multivariable analysis, hs-TnI was significantly associated with stroke or systemic embolism, adjusted hazard ratio 1.98 (1.42-2.78), P=0.0007. hs-TnI was also significantly associated with cardiac death; annual rates ranged from 0.40% to 4.24%, hazard ratio 4.52 (3.05-6.70), P<0.0001, in the corresponding groups, and for major bleeding hazard ratio 1.44 (1.11-1.86), P=0.0250. Adding hs-TnI levels to the CHA(2)DS(2)VASc score improved c-statistics from 0.629 to 0.653 for stroke or systemic embolism, and from 0.591 to 0.731 for cardiac death. There were no significant interactions with study treatment. Conclusions Troponin-I is detected in 98.5% and elevated in 9.2% of atrial fibrillation patients. The hs-TnI level is independently associated with a raised risk of stroke, cardiac death, and major bleeding and improves risk stratification beyond the CHA(2)DS(2)VASc score. The benefits of apixaban in comparison with warfarin are consistent regardless of hs-TnI levels.

    • ObjectivesThe aim of this study was to evaluate the prognostic value of high-sensitivity troponin T (hs-TnT) in addition to clinical risk factors and the CHA2DS2VASc (congestive heart failure, hypertension, 75 years of age and older, diabetes mellitus, previous stroke or transient ischemic attack, vascular disease, 65 to 74 years of age, female) risk score in patients with atrial fibrillation (AF).BackgroundThe level of troponin is a powerful predictor of cardiovascular events and mortality.MethodsA total of 14,897 patients with AF were randomized to treatment with apixaban or warfarin in the ARISTOTLE (Apixaban for the Prevention of Stroke in Subjects With Atrial Fibrillation) trial. The associations between baseline hs-TnT levels and outcomes were evaluated using adjusted Cox regression models.ResultsLevels of hs-TnT were measurable in 93.5% of patients; 75% had levels >7.5 ng/l, 50% had levels >11.0 ng/l, and 25% had levels >16.7 ng/l. During a median 1.9-year period, the annual rates of stroke or systemic embolism ranged from 0.87% in the lowest hs-TnT quartile to 2.13% in the highest hs-TnT quartile (adjusted hazard ratio [HR]: 1.94; 95% confidence interval [CI]: 1.35 to 2.78; p = 0.0010). The annual rates in the corresponding groups ranged from 0.46% to 4.24% (adjusted HR: 4.31; 95% CI: 2.91 to 6.37; p < 0.0001) for cardiac death and from 1.26% to 4.21% (adjusted HR: 1.91; 95% CI: 1.43 to 2.56; p = 0.0001) for major bleeding. Adding hs-TnT levels to the CHA2DS2VASc score improved the C statistic from 0.620 to 0.635 for stroke or systemic embolism (p = 0.0226), from 0.592 to 0.711 for cardiac death (p < 0.0001), and from 0.591 to 0.629 for major bleeding (p < 0.0001). Apixaban reduced rates of stroke, mortality, and bleeding regardless of the hs-TnT level.ConclusionsLevels of hs-TnT are often elevated in patients with AF. The hs-TnT level is independently associated with an increased risk of stroke, cardiac death, and major bleeding and improves risk stratification beyond the CHA2DS2VASc risk score. The benefits of apixaban as compared with warfarin are consistent regardless of the hs-TnT level. (Apixaban for the Prevention of Stroke in Subjects With Atrial Fibrillation [ARISTOTLE];

    • 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.

    • 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.

    • Background-We examined the risk of stroke or systemic embolism (SSE) conferred by heart failure (HF) and left ventricular systolic dysfunction (LVSD) in the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation Trial (ARISTOTLE), as well as the effect of apixaban versus warfarin. Methods and Results-The risk of a number of outcomes, including the composite of SSE or death (to take account of competing risks) and composite of SSE, major bleeding, or death (net clinical benefit) were calculated in 3 patient groups: (1) no HF/no LVSD (n=8728), (2) HF/no LVSD (n=3207), and (3) LVSD with/without symptomatic HF (n=2736). The rate of both outcomes was highest in patients with LVSD (SSE or death 8.06; SSE, major bleeding, or death 10.46 per 100 patient-years), intermediate for HF but preserved LV systolic function (5.32; 7.24), and lowest in patients without HF or LVSD (1.54; 5.27); each comparison P<0.0001. Each outcome was less frequent in patients treated with apixaban: in all ARISTOTLE patients, the apixaban/warfarin hazard ratio for SSE or death was 0.89 (95% confidence interval, 0.81-0.98; P=0.02); for SSE, major bleed, or death it was 0.85 (0.78-0.92; P<0.001). There was no heterogeneity of treatment effect across the 3 groups. Conclusions-Patients with LVSD (with/without HF) had a higher risk of SSE or death (but similar rate of SSE) compared with patients with HF but preserved LV systolic function; both had a greater risk than patients without either HF or LVSD. Apixaban reduced the risk of both outcomes more than warfarin in all 3 patient groups.

  • Aldosterone Does Not Predict Cardiovascular Events Following Acute Coronary Syndrome in Patients Initially Without Heart Failure
  • 2017
  • Ingår i: Journal of the American Heart Association. - : WILEY-BLACKWELL. - 2047-9980. ; 6:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background- Aldosterone may have adverse effects in the myocardium and vasculature. Treatment with an aldosterone antagonist reduces cardiovascular risk in patients with acute myocardial infarction complicated by heart failure (HF) and left ventricular systolic dysfunction. However, most patients with acute coronary syndrome do not have advanced HF. Among such patients, it is unknown whether aldosterone predicts cardiovascular risk. Methods and Results- To address this question, we examined data from the dal-OUTCOMES trial that compared the cholesteryl ester transfer protein inhibitor dalcetrapib with placebo, beginning 4 to 12 weeks after an index acute coronary syndrome. Patients with New York Heart Association class II (with LVEF amp;lt; 40%), III, or IV HF were excluded. Aldosterone was measured at randomization in 4073 patients. The primary outcome was a composite of coronary heart disease death, nonfatal myocardial infarction, stroke, hospitalization for unstable angina, or resuscitated cardiac arrest. Hospitalization for HF was a secondary endpoint. Over a median follow-up of 37 months, the primary outcome occurred in 366 patients (9.0%), and hospitalization for HF occurred in 72 patients (1.8%). There was no association between aldosterone and either the time to first occurrence of a primary outcome (hazard ratio for doubling of aldosterone 0.92, 95% confidence interval 0.78-1.09, P=0.34) or hospitalization for HF (hazard ratio 1.38, 95% CI 0.96-1.99, P=0.08) in Cox regression models adjusted for covariates. Conclusions- In patients with recent acute coronary syndrome but without advanced HF, aldosterone does not predict major cardiovascular events.

    • IMPORTANCE It is uncertain whether lipoprotein(a) [Lp(a)], which is associated with incident cardiovascular disease, is an independent risk factor for recurrent cardiovascular events after acute coronary syndrome (ACS). OBJECTIVE To determine the association of Lp(a) concentration measured after ACS with the subsequent risk of ischemic cardiovascular events. DESIGN, SETTING, AND PARTICIPANTS This nested case-cohort analysis was performed as an ad hoc analysis of the dal-Outcomes randomized clinical trial. This trial compared dalcetrapib, the cholesteryl ester transfer protein inhibitor, with placebo in patients with recent ACS and was performed between April 2008 and September 2012 at 935 sites in 27 countries. There were 969 case patients who experienced a primary cardiovascular outcome, and there were 3170 control patients who were event free at the time of a case event and had the same type of index ACS (unstable angina ormyocardial infarction) as that of the respective case patients. Concentration of Lp(a) was measured by immunoturbidimetric assay. Data analysis for this present study was conducted from June 8, 2016, to April 21, 2017. INTERVENTIONS Patients were randomly assigned to receive treatment with dalcetrapib, 600 mg daily, or matching placebo, beginning 4 to 12 weeks after ACS. MAIN OUTCOMES AND MEASURES Death due to coronary heart disease, a major nonfatal coronary event (myocardial infarction, hospitalization for unstable angina, or resuscitated cardiac arrest), or fatal or nonfatal ischemic stroke. RESULTS The mean (SD) age was 63 (10) years for the 969 case patients and 60 (9) years for the 3170 control patients, and both cohorts were composed of predominantly male (770 case patients [79%] and 2558 control patients [81%]; P = .40) and white patients (858 case patients [89%] and 2825 control patients [89%]; P = .62). At baseline, the median (interquartile range) Lp(a) level was 12.3 (4.7-50.9) mg/dL. There was broad application of evidence-based secondary prevention strategies after ACS, including use of statins in 4030 patients (97%). The cumulative distribution of baseline Lp(a) levels did not differ between cases and controls at P = .16. Case-cohort regression analysis showed no association of baseline Lp(a) level with risk of cardiovascular events. For a doubling of Lp(a) concentration, the hazard ratio (case to control) was 1.01 (95% CI, 0.96-1.06; P = .66) after adjustment for 16 baseline variables, including assigned study treatment. CONCLUSIONS AND RELEVANCE For patients with recent ACS who are treated with statins, Lp(a) concentration was not associated with adverse cardiovascular outcomes. These findings call into question whether treatment specifically targeted to reduce Lp(a) levels would thereby lower the risk for ischemic cardiovascular events after ACS.

    • OBJECTIVE Incident type 2 diabetes is common among patients with recent acute coronary syndrome and is associated with an adverse prognosis. Some data suggest that cholesteryl ester transfer protein (CETP) inhibitors reduce incident type 2 diabetes. We compared the effect of treatment with the CETP inhibitor dalcetrapib or placebo on incident diabetes in patients with recent acute coronary syndrome. RESEARCH DESIGN AND METHODS In the dal-OUTCOMES trial, 15,871 patients were randomly assigned to treatment with dalcetrapib 600 mg daily or placebo, beginning 4-12 weeks after an acute coronary syndrome. Absence of diabetes at baseline was based on medical history, no use of antihyperglycemic medication, and hemoglobin A(1c) and serum glucose levels below diagnostic thresholds. Among these patients, incident diabetes after randomization was defined by any diabetes-related adverse event, new use of antihyperglycemic medication, hemoglobin A(1c) >= 6.5%, or a combination of at least two measurements of serum glucose >= 7.0 mmol/L (fasting) or >= 11.1 mmol/L (random). RESULTS At baseline, 10,645 patients (67% of the trial cohort) did not have diabetes. During a median follow-up of 30 months, incident diabetes was identified in 403 of 5,326 patients (7.6%) assigned to dalcetrapib and in 516 of 5,319 (9.7%) assigned to placebo, corresponding to absolute risk reduction of 2.1%, hazard ratio of 0.77 (95% CI 0.68-0.88; P < 0.001), and a need to treat 40 patients for 3 years to prevent 1 incident case of diabetes. Considering only those with prediabetes at baseline, the number needed to treat for 3 years to prevent 1 incident case of diabetes was 25. Dalcetrapib also decreased the number of patients who progressed from normoglycemia to prediabetes and increased the number who regressed from diabetes to no diabetes. CONCLUSIONS In patients with a recent acute coronary syndrome, incident diabetes is common and is reduced substantially by treatment with dalcetrapib.

    • Among patients with heart failure and a reduced ejection fraction, those who received the cardiac myosin activator omecamtiv mecarbil had a lower incidence of a composite of heart-failure events or cardiovascular death at a median of 22 months than those who received placebo. Background The selective cardiac myosin activator omecamtiv mecarbil has been shown to improve cardiac function in patients with heart failure with a reduced ejection fraction. Its effect on cardiovascular outcomes is unknown. Methods We randomly assigned 8256 patients (inpatients and outpatients) with symptomatic chronic heart failure and an ejection fraction of 35% or less to receive omecamtiv mecarbil (using pharmacokinetic-guided doses of 25 mg, 37.5 mg, or 50 mg twice daily) or placebo, in addition to standard heart-failure therapy. The primary outcome was a composite of a first heart-failure event (hospitalization or urgent visit for heart failure) or death from cardiovascular causes. Results During a median of 21.8 months, a primary-outcome event occurred in 1523 of 4120 patients (37.0%) in the omecamtiv mecarbil group and in 1607 of 4112 patients (39.1%) in the placebo group (hazard ratio, 0.92; 95% confidence interval [CI], 0.86 to 0.99; P=0.03). A total of 808 patients (19.6%) and 798 patients (19.4%), respectively, died from cardiovascular causes (hazard ratio, 1.01; 95% CI, 0.92 to 1.11). There was no significant difference between groups in the change from baseline on the Kansas City Cardiomyopathy Questionnaire total symptom score. At week 24, the change from baseline for the median N-terminal pro-B-type natriuretic peptide level was 10% lower in the omecamtiv mecarbil group than in the placebo group; the median cardiac troponin I level was 4 ng per liter higher. The frequency of cardiac ischemic and ventricular arrhythmia events was similar in the two groups. Conclusions Among patients with heart failure and a reduced ejection, those who received omecamtiv mecarbil had a lower incidence of a composite of a heart-failure event or death from cardiovascular causes than those who received placebo.

    • Aims The safety and efficacy of the novel selective cardiac myosin activator, omecamtiv mecarbil, in patients with heart failure with reduced ejection fraction (HFrEF) is being tested in the Global Approach to Lowering Adverse Cardiac outcomes Through Improving Contractility in Heart Failure (GALACTIC-HF) trial. Here we describe the baseline characteristics of participants in GALACTIC-HF and how these compare with other contemporary trials. Methods and results Adults with established HFrEF, New York Heart Association (NYHA) functional class >= II, ejection fraction <= 35%, elevated natriuretic peptides and either current hospitalization for heart failure or history of hospitalization/emergency department visit for heart failure within a year were randomized to either placebo or omecamtiv mecarbil (pharmacokinetic-guided dosing: 25, 37.5, or 50 mg bid). A total of 8256 patients [male (79%), non-white (22%), mean age 65 years] were enrolled with a mean ejection fraction 27%, ischaemic aetiology in 54%, NYHA class II 53% and III/IV 47%, and median N-terminal pro-B-type natriuretic peptide 1971 pg/mL. Heart failure therapies at baseline were among the most effectively employed in contemporary heart failure trials. GALACTIC-HF randomized patients representative of recent heart failure registries and trials with substantial numbers of patients also having characteristics understudied in previous trials including more from North America (n = 1386), enrolled as inpatients (n = 2084), systolic blood pressure <100 mmHg (n = 1127), estimated glomerular filtration rate <30 mL/min/1.73 m(2) (n = 528), and treated with sacubitril/valsartan at baseline (n = 1594). Conclusions GALACTIC-HF enrolled a well-treated, high-risk population from both inpatient and outpatient settings, which will provide a definitive evaluation of the efficacy and safety of this novel therapy, as well as informing its potential future implementation.

    • BackgroundIn the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial, apixaban compared with warfarin reduced stroke and systemic embolism, major bleeding, and mortality. We evaluated treatment effects in relation to 2 predictions of time in therapeutic range (TTR).Methods and ResultsThe trial randomized 18 201 patients with atrial fibrillation to apixaban 5 mg twice daily or warfarin for at least 12 months. For each patient, a center average TTR was estimated with the use of a linear mixed model on the basis of the real TTRs in its warfarin-treated patients, with a fixed effect for country and random effect for center. For each patient, an individual TTR was also predicted with the use of a linear mixed effects model including patient characteristics as well. Median center average TTR was 66% (interquartile limits, 61% and 71%). Rates of stroke or systemic embolism, major bleeding, and mortality were consistently lower with apixaban than with warfarin across center average TTR and individual TTR quartiles. In the lowest and highest center average TTR quartiles, hazard ratios for stroke or systemic embolism were 0.73 (95% confidence interval [CI], 0.53–1.00) and 0.88 (95% CI, 0.57–1.35) (Pinteraction=0.078), for mortality were 0.91 (95% CI, 0.74–1.13) and 0.91 (95% CI, 0.71–1.16) (Pinteraction=0.34), and for major bleeding were 0.50 (95% CI, 0.36–0.70) and 0.75 (95% CI, 0.58–0.97) (Pinteraction=0.095), respectively. Similar results were seen for quartiles of individual TTR.ConclusionsThe benefits of apixaban compared with warfarin for stroke or systemic embolism, bleeding, and mortality appear similar across the range of centers’ and patients’ predicted quality of international normalized ratio control.Clinical Trial RegistrationURL: http://www.clinicaltrials.gov.

    • IMPORTANCE The Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) trial reported that apixaban therapy was superior to warfarin therapy in preventing stroke and all-cause death while causing significantly fewer major bleeds. To establish the value proposition of substituting apixiban therapy for warfarin therapy in patients with atrial fibrillation, we performed a cost-effectiveness analysis using patient-level data from the ARISTOTLE trial.OBJECTIVE To assess the cost and cost-effectiveness of apixaban therapy compared with warfarin therapy in patients with atrial fibrillation from the perspective of the US health care system.DESIGN, SETTING, AND PARTICIPANTS This economic analysis uses patient-level resource use and clinical data collected in the ARISTOTLE trial, a multinational randomized clinical trial that observed 18 201 patients (3417 US patients) for a median of 1.8 years between 2006 and 2011.INTERVENTIONS Apixaban therapy vs warfarin therapy.MAIN OUTCOMES AND MEASURES Within-trial resource use and costwere compared between treatments, using externally derived US cost weights. Life expectancies for US patients were estimated according to their baseline risk and treatment using time-based and age-based survival models developed using the overall ARISTOTLE population. Quality-of-life adjustment factors were obtained from external sources. Cost-effectiveness (incremental cost per quality-adjusted life-year gained) was evaluated from a US perspective, and extensive sensitivity analyses were performed.RESULTS Of the 3417 US patients enrolled in ARISTOTLE, the mean (SD) age was 71 (10) years; 2329 (68.2%) were male and 3264 (95.5%) were white. After 2 years of anticoagulation therapy, health care costs (excluding the study drug) of patients treated with apixaban therapy and warfarin therapy were not statistically different (difference, -$ 60; 95% CI, -$ 2728 to $ 2608). Life expectancy, modeled from ARISTOTLE outcomes, was significantly longer with apixaban therapy vs warfarin therapy (7.94 vs 7.54 quality-adjusted life years). The incremental cost, including cost of anticoagulant and monitoring, of achieving these benefits was within accepted US norms ($ 53 925 per quality-adjusted life year, with 98% likelihood of meeting a $ 100 000 willingness-to-pay threshold). Results were generally consistent when model assumptions were varied, with lifetime cost-effectiveness most affected by the price of apixaban and the time horizon.CONCLUSIONS AND RELEVANCE Apixaban therapy for ARISTOTLE-eligible patients with atrial fibrillation provides clinical benefits at an incremental cost that represents reasonable value for money judged using US benchmarks for cost-effectiveness.

    • BACKGROUND: Patients recently hospitalized for heart failure (HF) are at high risk for rehospitalization and death. OBJECTIVES: The purpose of this study was to investigate clinical outcomes and response to dapagliflozin in patients with HF with mildly reduced or preserved left ventricular ejection fraction (LVEF) who were enrolled during or following hospitalization. METHODS: The DELIVER (Dapagliflozin Evaluation to Improve the LIVES of Patients With PReserved Ejection Fraction Heart Failure) trial randomized patients with HF and LVEF $>$40% to dapagliflozin or placebo. DELIVER permitted randomization during or shortly after hospitalization for HF in clinically stable patients off intravenous HF therapies. This prespecified analysis investigated whether recent HF hospitalization modified risk of clinical events or response to dapagliflozin. The primary outcome was worsening HF event or cardiovascular death. RESULTS: Of 6,263 patients in DELIVER, 654 (10.4%) were randomized during HF hospitalization or within 30 days of discharge. Recent HF hospitalization was associated with greater risk of the primary outcome after multivariable adjustment (HR: 1.88; 95% CI: 1.60-2.21; P $<$ 0.001). Dapagliflozin reduced the primary outcome by 22% in recently hospitalized patients (HR: 0.78; 95% CI: 0.60-1.03) and 18% in patients without recent hospitalization (HR: 0.82; 95% CI: 0.72-0.94; Pinteraction = 0.71). Rates of adverse events, including volume depletion, diabetic ketoacidosis, or renal events, were similar with dapagliflozin and placebo in recently hospitalized patients. CONCLUSIONS: Dapagliflozin safely reduced risk of worsening HF or cardiovascular death similarly in patients with and without history of recent HF hospitalization. Starting dapagliflozin during or shortly after HF hospitalization in patients with mildly reduced or preserved LVEF appears safe and effective.

    • AIMS: Whether diabetes without insulin therapy is an independent cardiovascular (CV) risk factor in atrial fibrillation (AF) has recently been questioned. We investigated the prognostic relevance of diabetes with or without insulin treatment in patients in the ARISTOTLE trial.METHODS AND RESULTS: Patients with AF and increased stroke risk randomized to apixaban vs. warfarin were classified according to diabetes status: no diabetes; diabetes on no diabetes medications; diabetes on non-insulin antidiabetic drugs only; or insulin-treated. The associations between such patient subgroups and stroke/systemic embolism (SE), myocardial infarction (MI), and CV death were examined by Cox proportional hazard regression, both unadjusted and adjusted for other prognostic variables. Patients with diabetes were younger and had a higher body mass index. Median CHA2DS2VASc score was 4.0 in patients with diabetes and 3.0 in patients without diabetes. We found no significant difference in stroke/SE incidence across patient subgroups. Compared with no diabetes, only insulin-treated diabetes was significantly associated with higher risk. When adjusted for clinical variables, compared with no diabetes, the hazard ratios (HRs) for MI (95% confidence intervals) were for diabetes on no medication: 1.15 (0.62-2.14); for diabetes on non-insulin antidiabetic drugs: 1.32 (0.90-1.94); for insulin-treated diabetes: 2.34 (1.43-3.82); interaction P = 0.008. HRs for CV death were for diabetes on no medication: 1.19 (0.86-166); for diabetes on non-insulin antidiabetic drugs: 1.12 (0.88-1.42); for insulin-treated diabetes 1.85 (1.36-2.53), interaction P = 0.001.CONCLUSION: In anticoagulated patients with AF, a higher risk of MI and CV death is largely confined to diabetes treated with insulin.

    • PURPOSE: Vitamin K antagonists (VKAs) are the standard of care for stroke prevention in patients with atrial fibrillation (AF); therefore, there is not equipoise when comparing newer oral anticoagulants with placebo in this setting.METHODS: To explore the effect of apixaban on mortality in patients with AF, we performed a meta-analysis of apixaban versus placebo using a putative placebo analysis based on randomized controlled clinical trials that compared warfarin, aspirin, and no antithrombotic control. We used data from two prospective randomized controlled trials for our comparison of apixaban versus warfarin (Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation) and apixaban versus aspirin (Apixaban Versus Acetylsalicylic Acid to Prevent Stroke in Atrial Fibrillation Patients Who Have Failed or Are Unsuitable for Vitamin K Antagonist Treatment). Using meta-analysis approaches, we indirectly compared apixaban with an imputed placebo with respect to the risk of death in patients with AF. We used results from meta-analyses of randomized trials as our reference for the comparison between warfarin and placebo/no treatment, and aspirin and placebo/no treatment.RESULTS: In these meta-analyses, a lower rate of death was seen both with warfarin (odds ratio [OR] 0.74, 95% confidence interval [CI] 0.57-0.97) and aspirin (OR 0.86, 95% CI 0.69-1.07) versus placebo/no treatment. Using data from ARISTOTLE and AVERROES, apixaban reduced the risk of death by 34% (95% CI 12-50%; p = 0.004) and 33% (95% CI 6-52%; p = 0.02), respectively, when compared with an imputed placebo. The pooled reduction in all-cause death with apixaban compared with an imputed placebo was 34% (95% CI 18-47%; p = 0.0002).CONCLUSIONS: In patients with AF, indirect comparisons suggest that apixaban reduces all-cause death by approximately one third compared with an imputed placebo.

    • 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.

    • This pre-specified analysis of DAPA-CKD assessed the impact of sodium-glucose cotransporter 2 inhibition on abrupt declines in kidney function in high-risk patients based on having chronic kidney disease (CKD) and substantial albuminuria. DAPA-CKD was a randomized, double-blind, placebo-controlled trial that had a median follow-up of 2.4 years. Adults with CKD (urinary albumin-to-creatinine ratio 200-5000 mg/g and estimated glomerular filtration rate 25-75 mL/min/1.73m2) were randomized to dapagliflozin 10 mg/day matched to placebo (2152 individuals each). An abrupt decline in kidney function was defined as a pre-specified endpoint of doubling of serum creatinine between two subsequent study visits. We also assessed a post-hoc analysis of investigator-reported acute kidney injury-related serious adverse events. Doubling of serum creatinine between two subsequent visits (median time-interval 100 days) occurred in 63 (2.9%) and 91 (4.2%) participants in the dapagliflozin and placebo groups, respectively (hazard ratio 0.68 [95% confidence interval 0.49, 0.94]). Accounting for the competing risk of mortality did not alter our findings. There was no heterogeneity in the effect of dapagliflozin on abrupt declines in kidney function based on baseline subgroups. Acute kidney injury-related serious adverse events were not significantly different and occurred in 52 (2.5%) and 69 (3.2%) participants in the dapagliflozin and placebo groups, respectively (0.77 [0.54, 1.10]). Thus, in patients with CKD and substantial albuminuria, dapagliflozin reduced the risk of abrupt declines in kidney function.

    • AIMS: Mortality rates from chronic kidney disease (CKD) have increased in the last decade. In this pre-specified analysis of the DAPA-CKD trial, we determined the effects of dapagliflozin on cardiovascular and non-cardiovascular causes of death.METHODS AND RESULTS: DAPA-CKD was an international, randomized, placebo-controlled trial with a median of 2.4 years of follow-up. Eligible participants were adult patients with CKD, defined as a urinary albumin-to-creatinine ratio (UACR) 200-5000 mg/g and an estimated glomerular filtration rate (eGFR) 25-75 mL/min/1.73 m2. All-cause mortality was a key secondary endpoint. Cardiovascular and non-cardiovascular death was adjudicated by an independent clinical events committee. The DAPA-CKD trial randomized participants to dapagliflozin 10 mg/day (n = 2152) or placebo (n = 2152). The mean age was 62 years, 33% were women, the mean eGFR was 43.1 mL/min/1.73 m2, and the median UACR was 949 mg/g. During follow-up, 247 (5.7%) patients died, of whom 91 (36.8%) died due to cardiovascular causes, 102 (41.3%) due to non-cardiovascular causes, and in 54 (21.9%) patients, the cause of death was undetermined. The relative risk reduction for all-cause mortality with dapagliflozin (31%, hazard ratio [HR] [95% confidence interval (CI)] 0.69 [0.53, 0.88]; P = 0.003) was consistent across pre-specified subgroups. The effect on all-cause mortality was driven largely by a 46% relative risk reduction of non-cardiovascular death (HR [95% CI] 0.54 [0.36, 0.82]). Deaths due to infections and malignancies were the most frequently occurring causes of non-cardiovascular deaths and were reduced with dapagliflozin vs. placebo.CONCLUSION: In patients with CKD, dapagliflozin prolonged survival irrespective of baseline patient characteristics. The benefits were driven largely by reductions in non-cardiovascular death.

    • OBJECTIVE:This study sought to assess the prognostic value of N-terminal pro–B-type natriuretic peptide (NT-proBNP) in patients with atrial fibrillation (AF) enrolled in the ARISTOTLE (Apixaban for the Prevention of Stroke in Subjects With Atrial Fibrillation) trial, and the treatment effect of apixaban according to NT-proBNP levels.BACKGROUND:Natriuretic peptides are associated with mortality and cardiovascular events in several cardiac diseases.METHODS:In the ARISTOTLE trial, 18,201 patients with AF were randomized to apixaban or warfarin. Plasma samples at randomization were available from 14,892 patients. The association between NT-proBNP concentrations and clinical outcomes was evaluated using Cox proportional hazard models, after adjusting for established cardiovascular risk factors.RESULTS:Quartiles of NT-proBNP were Q1:≤363, Q2:364-713, Q3:714-1250 and Q4:>1250 ng/L. During 1.8 years the annual rates of stroke or systemic embolism ranged from 0.74% in the bottom NT-proBNP quartile to 2.21% in the top quartile, adjusted hazard ratio (HR) 2.35 (95% CI 1.62-3.40, p<0.0001. Annual rates of cardiac death ranged from 0.86% in Q1 to 4.14% in Q4, adjusted HR 2.50 (1.81-3.45), p<0.0001. Adding NT-proBNP levels to the CHA2DS2VASc score improved C-statistics from 0.62 to 0.65 (p=0.0009) for stroke or systemic embolism and from 0.59 to 0.69 for cardiac death (p<0.0001). Apixaban reduced stroke, mortality, and bleeding regardless of the NT-proBNP level.CONCLUSIONS:NT-proBNP levels are often elevated in AF and independently associated with an increased risk of stroke and mortality. NT-proBNP improves risk stratification beyond the CHA2DS2VASc score and might be a novel tool for improved stroke prediction in AF. The efficacy of apixaban compared with warfarin is independent of the NT-proBNP level. (Apixaban for the Prevention of Stroke in Subjects With Atrial Fibrillation [ARISTOTLE].

    • BACKGROUND: Patients with heart failure with mildly reduced ejection fraction (HFmrEF) and heart failure with preserved ejection fraction (HFpEF) experience a high burden of symptoms, physical limitations, and poor quality of life; improving health status is a key goal of management. OBJECTIVES: In a prespecified analysis of the DELIVER (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure) trial, we examine effects of dapagliflozin on health status using the Kansas City Cardiomyopathy Questionnaire (KCCQ). METHODS: The DELIVER trial randomized patients with symptomatic HFmrEF/HFpEF to dapagliflozin 10 mg or placebo. KCCQ was evaluated at randomization, 1, 4, and 8 months; KCCQ Total Symptom Score (TSS) was a key secondary endpoint. Patients were stratified by KCCQ-TSS tertiles; Cox models examined effects of dapagliflozin on clinical outcomes. We evaluated the effects of dapagliflozin on KCCQ-TSS, Physical Limitations (PLS), Clinical Summary (CSS), and Overall Summary (OSS) domains. Responder analyses compared proportions of dapagliflozin vs placebo-treated patients with clinically meaningful changes in KCCQ. RESULTS: A total of 5,795 patients had baseline KCCQ (median KCCQ-TSS 72.9). The effects of dapagliflozin on reducing cardiovascular death/worsening HF appeared more pronounced in patients with greater baseline symptom burden (lowest-to-highest KCCQ-TSS tertile: HR: 0.70 [95% CI: 0.58-0.84]; 0.81 [95% CI: 0.65-1.01]; 1.07 [95% CI: 0.83-1.37]; Pinteraction = 0.026). Dapagliflozin improved KCCQ-TSS, -PLS, -CSS, and -OSS at 8 months (2.4, 1.9, 2.3, and 2.1 points higher vs placebo; P $<$ 0.001 for all). Dapagliflozin-treated patients experienced improvements in KCCQ-TSS regardless of EF (Pinteraction = 0.85). Fewer dapagliflozin- treated patients had deterioration, and more had improvements in all KCCQ domains at 8 months. CONCLUSIONS: The clinical benefits of dapagliflozin in HFmrEF/HFpEF appear especially pronounced in those with greater baseline symptom impairment. Dapagliflozin improved all KCCQ domains and the proportion of patients experiencing clinically meaningful changes in health status.

    • BACKGROUND It is unknown how the efficacy and safety of mineralocorticoid receptor antagonists vary according to duration of heart failure with reduced ejection fraction (HFrEF).OBJECTIVES In this study, we sought to evaluate the safety and efficacy of eplerenone according to duration of HFrEF. METHODS In the EMPHASIS-HF trial, 3 patient groups were created according to HFrEF duration: <1 year, 1 to <5 years, and >= 5 years. The primary outcome was the composite of heart failure (HF) hospitalization or cardiovascular death. Outcomes were adjusted for prespecified prognostic variables and examined with the use of Cox regression models.RESULTS The numbers of patients in each group were: 975, <1 year; 769, 1 to <5 years; and 988, >= 5 years. Patients with longer-standing HF were older and more frequently had cardiovascular and noncardiovascular comorbidities. The rate of the primary outcome (per 100 person-years) increased with HFrEF duration: 9.8 (95% CI: 8.4-11.4) for <1 year, 13.5 (95% CI: 11.6-15.7) for 1 to <5 years, and 17.6 (95% CI: 15.6-19.8) for >= 5 years. The benefits of eplerenone were consistent across HF duration: HRs for the primary outcome were 0.57 (95% CI: 0.42-0.79) for <1 year, 0.81 (95% CI: 0.60-1.10) for 1 to <5 years, and 0.61 (95% CI: 0.48-0.78) for >= 5 years; Pinteraction 1/4 0.24. The absolute benefit was greatest in the longest-duration group: the number needed to treat for the primary outcome was 14 for <1 year, 13 for 1 to <5 years, and 10 for >= 5 years duration. CONCLUSIONS Patients with longer-standing HFrEF had worse clinical status and a higher rate of events, but the benefit of eplerenone was consistent regardless of HFrEF duration.

    • Background:Dapagliflozin reduces the risk of end-stage renal disease in patients with chronic kidney disease. We examined the relative risk of cardiovascular and renal events in these patients and the effect of dapagliflozin on either type of event, taking account of history of cardiovascular disease.Methods:In the DAPA-CKD trial (Dapagliflozin and Prevention of Adverse Outcomes in Chronic Kidney Disease), 4304 participants with chronic kidney disease were randomly assigned to dapagliflozin 10 mg once daily or placebo. The primary end point was a composite of sustained decline in estimated glomerular filtration rate ≥50%, end-stage kidney disease, or kidney or cardiovascular death. The secondary end points were a kidney composite outcome (primary end point, minus cardiovascular death), the composite of hospitalization for heart failure or cardiovascular death, and all-cause death. In a prespecified subgroup analysis, we divided patients into primary and secondary prevention subgroups according to history of cardiovascular disease.Results:Secondary prevention patients (n=1610; 37.4%) were older, were more often male, had a higher blood pressure and body mass index, and were more likely to have diabetes. Mean estimated glomerular filtration rate and median urinary albumin-to-creatinine ratio were similar in the primary and secondary prevention groups. The rates of adverse cardiovascular outcomes were higher in the secondary prevention group, but kidney failure occurred at the same rate in the primary and secondary prevention groups. Dapagliflozin reduced the risk of the primary composite outcome to a similar extent in both the primary (hazard ratio, 0.61 [95% CI, 0.48–0.78]) and secondary (0.61 [0.47–0.79]) prevention groups (P-interaction=0.90). This was also true for the composite of heart failure hospitalization or cardiovascular death (0.67 [0.40–1.13] versus 0.70 [0.52–0.94], respectively; P-interaction=0.88), and all-cause mortality (0.63 [0.41–0.98] versus 0.70 [0.51–0.95], respectively; P-interaction=0.71). Rates of adverse events were low overall and did not differ between patients with and without cardiovascular disease.Conclusions:Dapagliflozin reduced the risk of kidney failure, death from cardiovascular causes or hospitalization for heart failure, and prolonged survival in people with chronic kidney disease, with or without type 2 diabetes, independently of the presence of concomitant cardiovascular disease.Registration:URL: https://www.clinicaltrials.gov; Unique identifier: NCT03036150.

    • 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.

    • Visit-to-visit office blood pressure (BP) variability (BPV) has been associated with morbidity and mortality outcomes in several cardiovascular conditions. The aim of this study was to evaluate the association between BPV and outcomes in patients with heart failure and reduced ejection fraction and the effect of eplerenone on BPV.We evaluated the associations between BPV, calculated as SBP coefficient of variation (SBP-CoV=SD/mean×100%), and the primary composite endpoint of cardiovascular mortality or heart failure hospitalization (HFH), and its components, in 2549 patients from the Eplerenone in Patients with Systolic Heart Failure and Mild Symptoms trial. Lower SBP-CoV was independently associated with a higher risk of all the studied outcomes, while higher as well as lower SBP-CoV were associated with a higher risk of cardiovascular death. After a median follow-up period of 21 months the risk of the composite outcome of cardiovascular death or HFH was almost double in the lower SBP-CoV tertile as compared with the intermediate tertile [adjusted hazard ratio: 2.01, 95% confidence interval (1.62-2.51), P<0.001]. The relationship between SBP-CoV and outcomes was not modified by eplerenone (P value for interaction=0.48). An interaction was detected between mean SBP and SBP-CoV for the primary outcome (P=0.048) and for HFH (P=0.018). The effect modification was slight, but lower SBP-CoV was associated with worse outcomes in patients with both low and high SBP, while this interaction was less clear for patients with SBP in the 'normal' range.In our patients with heart failure and reduced ejection fraction and mild symptoms, both a lower and higher SBP-CoV were associated with worse outcomes. SBP-CoV did not modify the benefit of eplerenone. Further studies are warranted to clarify the role of BPV in heart failure. CLINICALTRIALS.NCT00232180.

  • Dapagliflozin and New York Heart Association Functional Class in Heart Failure with Mildly Reduced or Preserved Ejection Fraction : The DELIVER Trial.
  • 2022
  • Ingår i: European journal of heart failure. - : Wiley. - 1388-9842 .- 1879-0844. ; 24:10, s. 1892-1901
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: This pre-specified analysis of the DELIVER trial examined whether clinical benefits of dapagliflozin in heart failure (HF) with left ventricular ejection fraction (LVEF) $>$40% varied by baseline New York Heart Association (NYHA) class and examined the treatment effects on NYHA class over time. METHODS AND RESULTS: Treatment effects of dapagliflozin by baseline NYHA class II (n = 4713) versus III/IV (n = 1549) were examined on the primary endpoint (cardiovascular death or worsening HF event) and key secondary endpoints. Effects of dapagliflozin on change in NYHA class at 4, 16, and 32 weeks were also evaluated. Higher baseline NYHA class was associated with older age, female sex, greater comorbidity burden, lower LVEF, and higher natriuretic peptide levels. Participants with baseline NYHA class III/IV, as compared with II, were independently more likely to experience the primary endpoint (adjusted hazard ratio [HR] 1.16 [95% confidence interval, 1.02-1.33]) and all-cause death (adjusted HR 1.22 [1.06-1.40]). Dapagliflozin consistently reduced the risk of the primary endpoint compared with placebo, irrespective of baseline NYHA class (HR 0.81 [0.70-0.94] for NYHA class II vs. HR 0.80 [0.65-0.98] for NYHA class III/IV; pinteraction = 0.921). Participants with NYHA class III/IV had greater improvement in Kansas City Cardiomyopathy Questionnaire total symptom scores between baseline and 32 weeks (+4.8 [2.5-7.1]) versus NYHA class II (+1.8 [0.7-2.9]; pinteraction = 0.011). Dapagliflozin was associated with higher odds of any improvement in NYHA class (odds ratio [OR] 1.32 [1.16-1.51]), as well as improvement to NYHA class I (OR 1.43 [1.17-1.75]), versus placebo at 32 weeks, with benefits seen as early as 4 weeks. CONCLUSIONS: Among symptomatic patients with HF and LVEF $>$40%, treatment with dapagliflozin provided clinical benefit irrespective of baseline NYHA class and was associated with early and sustained improvements in NYHA class over time.

  • Efficacy and Safety of Dapagliflozin in Heart Failure With Mildly Reduced or Preserved Ejection Fraction According to Age : The DELIVER Trial.
  • 2022
  • Ingår i: Circulation. Heart failure. ; 15:10
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: The prevalence of heart failure with mildly reduced or preserved ejection fraction markedly increases with age, with older individuals disproportionately facing excess risk for mortality and hospitalization. METHODS: The DELIVER trial (Dapagliflozin Evaluation to Improve the Lives of Patients With Preserved Ejection Fraction Heart Failure) randomized patients with New York Heart Association functional class II-IV and left ventricular ejection fraction $>$40% to either dapagliflozin or placebo for a median follow-up period of 2.3 years. We examined efficacy and safety outcomes by age categories ($<$55, 55-64, 65-74, and $>$/=75 years) and across age as a continuous measure. RESULTS: Among 6263 randomized patients (aged 40-99 years, mean age 71.7+/-9.6 years), 338 (5.4%) were $<$55 years, 1007 (16.1%) were 55-64 years, 2326 (37.1%) were 65 to 74 years, and 2592 (41.4%) were $>$/=75 years. Dapagliflozin reduced the risk of the primary composite outcome compared with placebo in all age categories (Pinteraction=0.95) and across the age spectrum as a continuous function (Pinteraction=0.76). Similar benefits were observed for the components of the primary outcome, with no significant interaction between randomized treatment and age category. Adverse events occurred more frequently with increasing age, but there were no significant differences in predefined safety outcomes between patients randomized to dapagliflozin and placebo across all age categories. CONCLUSIONS: In patients with heart failure and mildly reduced or preserved ejection fraction enrolled in DELIVER, dapagliflozin reduced the combined risk of cardiovascular death or worsening heart failure events across the spectrum of age, with a consistent safety profile, including among the traditionally under-treated older segment of patients $>$/=75 years.

  • Impact of eplerenone on cardiovascular outcomes in heart failure patients with hypokalaemia
  • 2017

    • © 2016 The Authors. European Journal of Heart Failure © 2016 European Society of Cardiology Aims: Although hypokalaemia is common among patients with heart failure (HF), the prognostic significance of baseline hypokalaemia and hypokalaemia during follow-up in HF patients receiving a mineralocorticoid receptor antagonist (MRA) remains uncertain. Methods and results: Results of the EMPHASIS-HF trial in patients (n = 2737) with HF and reduced EF with mild symptoms, randomized to eplerenone or placebo, were analysed with regard to the presence or occurrence of hypokalaemia (serum K + < 4.0 mmol/L) and the risk of cardiovascular death or hospitalization for HF (primary endpoint). Median follow-up was 21 months. Baseline hypokalaemia and hypokalaemia during follow-up were common occurrences (19.6% and 40.6%, respectively). Hypokalaemia during follow-up was associated with worse outcomes in multivariable analyses [hazard ratio (HR) 1.26, 95% confidence interval (CI) 1.05–1.52, P = 0.01] without evidence of interaction with eplerenone. In contrast, baseline hypokalaemia was associated with outcomes in the placebo group (HR 1.37, 95% CI 1.05–1.79, P = 0.02) but not in the eplerenone group (HR 0.87, 95% CI 0.62–1.23, P = 0.44; P for interaction = 0.04). Concurrently, eplerenone was found to be more protective in patients with baseline hypokalaemia vs. patients without baseline hypokalaemia compared with placebo (HR 0.44, 95% 0.30–0.64, P < 0.0001 vs. 0.69, 95% CI 0.57–0.83, P = 0.0001; P for interaction = 0.04). In patients without baseline hypokalaemia, eplerenone use decreased the rate of hypokalaemia during follow-up (HR 0.69, 95% CI 0.59–0.80, P < 0.001). A potassium level > 4.0 mmol/L at 1 month after randomization mediated 26.0% (0.6–51.4%) of the eplerenone treatment effect (P = 0.04). Conclusion: In HF patients receiving optimal therapy but not treated with eplerenone, baseline hypokalaemia was associated with worse outcomes. Conversely, hypokalaemia amplified the treatment effect of eplerenone.
