  • Prevalence and prognostic impact of bundle branch block in patients with heart failure: Evidence from the CHARM programme
  • 2007
  • Ingår i: European journal of heart failure. - : Wiley. - 1388-9842. ; 9:5, s. 510-7
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Bundle branch block (BBB) is a powerful independent predictor of cardiovascular mortality in patients with heart failure (HF) and reduced left ventricular ejection fraction (LVEF). The prognostic implications in HF with preserved systolic function (HF-PSF) are less well understood. METHODS: The Candesartan in Heart failure: Assessment of Reduction in Mortality and morbidity (CHARM) programme randomised 7599 patients with symptomatic HF to receive candesartan or placebo. The primary outcome comprised cardiovascular death or HF hospitalisation. The relative risk conveyed by BBB relative to a normal electrocardiogram was examined. RESULTS: The prevalence of BBB was significantly lower in patients with preserved compared with reduced systolic function (CHARM-Preserved 14.4%, Alternative 29.6%, Added 30.5%), p<0.0001. Overall, the adjusted hazard ratio for the primary outcome was 1.48 (95% confidence interval 1.22-1.78), p<0.0001, reflecting increased risk in patients with reduced LVEF (1.72 [1.28-2.31], p=0.0003). The apparently more modest risk among patients with HF-PSF was significant in unadjusted (1.80 [1.37-2.37], p<0.0001) but not adjusted analysis (1.16 [0.88-1.54], p=0.2897). However, no formal statistical difference was observed between the two cohorts, and interpretation is limited by the unknown prevalence of left and right BBB morphologies in each. Comparing BBB presence with absence yielded qualitatively similar results. CONCLUSION: The simple clinical finding of BBB is a powerful independent predictor of worse clinical outcomes in patients with HF and reduced LVEF. It is less frequent, with a more modest predictive effect, in patients with preserved systolic function.

  • Prevalence and prognostic implications of electrocardiographic left ventricular hypertrophy in heart failure: evidence from the CHARM programme
  • 2007
  • Ingår i: Heart. - : BMJ. - 1468-201X .- 1355-6037. ; 93:1, s. 59-64
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Electrocardiographic left ventricular hypertrophy (ECG LVH) is a powerful independent predictor of cardiovascular morbidity and mortality in hypertension. OBJECTIVE: To determine the contemporary prevalence and prognostic implications of ECG LVH in a broad spectrum of patients with heart failure with and without reduced left ventricular ejection fraction (LVEF). METHODS AND OUTCOME: The Candesartan in Heart failure: Assessment of Reduction in Mortality and morbidity (CHARM) programme randomised 7599 patients with symptomatic heart failure to receive candesartan or placebo. The primary outcome comprised cardiovascular death or hospital admission for worsening heart failure. The relative risk (RR) conveyed by ECG LVH compared with a normal ECG was examined in a Cox model, adjusting for as many as 31 covariates of prognostic importance. RESULTS: The prevalence of ECG LVH was similar in all three CHARM trials (Alternative, 15.4%; Added, 17.1%; Preserved, 14.7%; Overall, 15.7%) despite a more frequent history of hypertension in CHARM-Preserved. ECG LVH was an independent predictor of worse prognosis in CHARM-Overall. RR for the primary outcome was 1.27 (95% confidence interval (CI) 1.04 to 1.55, p = 0.018). The risk of secondary end points was also increased: cardiovascular death, 1.50 (95% CI 1.13 to 1.99, p = 0.005); hospitalisation due to heart failure, 1.19 (95% CI 0.94 to 1.50, p = 0.148); and composite major cardiovascular events, 1.35 (95% CI 1.12 to 1.62, p = 0.002). CONCLUSION: ECG LVH is similarly prevalent in patients with symptomatic heart failure regardless of LVEF. The simple clinical finding of ECG LVH was an independent predictor of a worse clinical outcome in a broad spectrum of patients with heart failure receiving extensive contemporary treatment. Candesartan had similar benefits in patients with and without ECG LVH.

  • Standard medication information is not enough : poor concordance of patient and nurse perceptions
  • 2007
  • Ingår i: Journal of Advanced Nursing. - : Wiley-Blackwell. - 0309-2402 .- 1365-2648. ; 60:2, s. 181-186
  • Tidskriftsartikel (refereegranskat)abstract
    • AIM:This paper is a report of a study to describe patient and nurse perceptions of patient satisfaction with information about the medicines at two heart failure clinics after medication up-titration and information-giving.BACKGROUND:Chronic heart failure is a major cause of hospitalization. Poor adherence to medications increases mortality and heart failure-related hospitalizations. To achieve mutual goal-setting (concordance) regarding medication-taking behaviours, health providers need to understand patient information needs regarding the prescribed medicines.METHODS:A convenience sample of 56 patients with chronic heart failure referred for an up-titration of medicines and information-giving about the condition and treatment completed the Satisfaction about Information about Medicines Scale at their first and last visits. Nurses completed the same questionnaire after each patient's final visit, assessing the patient's need for further information. The data were collected between 2002 and 2004.RESULTS:Patient scores indicated statistically significantly more satisfaction with their information at the final visit compared with the first visit (P = 0.005). However, at the programme conclusion, nurses (n = 7) rated patients to be appropriately informed while patients reported a persistent need for further information (P = 0.011).CONCLUSION:Further research should evaluate more advanced pedagogical strategies such as how to address patients' expectations about the effect of medicines when actual effects of the treatment are related to mortality and morbidity at the population level and may not result directly in symptom relief at an individual level.

  • Effect of carvedilol and metoprolol on the mode of death in patients with heart failure
  • 2007
  • Ingår i: Eur J Heart Fail. - : Wiley. - 1388-9842 .- 1879-0844. ; 9:11, s. 1128-35
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: In the COMET study, carvedilol improved survival compared to metoprolol tartrate in 3029 patients with NYHA II-IV heart failure and EF <35%, followed for an average of 58 months. AIMS: To evaluate whether the effect on overall mortality was specific for a particular mode of death. This may help to identify the mechanism of the observed difference. METHODS: Of the 1112 total deaths, 972 were adjudicated as cardiovascular, including 480 sudden, 365 circulatory failure (CF) and 51 stroke deaths. For each mode of death, the effect of pre-specified baseline variables was assessed, including sex, age, NYHA class, aetiology, heart rate, systolic blood pressure, EF, atrial fibrillation, previous myocardial infarction or hypertension, renal function, concomitant medication, and study treatment allocation. RESULTS: In multivariate Cox regression analyses, compared to metoprolol, carvedilol reduced cardiovascular (RR 0.80, CI 0.7-0.91, p=0.0009), sudden (RR 0.77, CI 0.64-0.93, p=0.0073) and stroke deaths (RR 0.37, CI 0.19-0.71, p=0.0027) with a non-significant trend for CF death (RR 0.83, CI 0.66-1.04, p=0.07). Treatment benefit with carvedilol did not differ between modes of death, except for a greater reduction in stroke death with carvedilol (competing risk analysis, p=0.0071 vs CF death). There were no interactions between treatment allocation and baseline characteristics. CONCLUSION: Mortality reduction with carvedilol compared to metoprolol appears relatively non-specific and could be consistent with a superior effect of carvedilol on cardiac function, arrhythmias or, in view of the greater reduction in stroke deaths, on vascular events.

  • Acute heart failure syndromes: clinical scenarios and pathophysiologic targets for therapy
  • 2007
  • Ingår i: Heart Fail Rev. - : Springer Science and Business Media LLC. - 1382-4147 .- 1573-7322. ; 12:2, s. 97-104
  • Forskningsöversikt (refereegranskat)abstract
    • Acute heart failure syndromes (AHFS) represent the most common discharge diagnosis in patients over age 65 years, with an exceptionally high mortality and readmission rates at 60-90 days. Recent surveys and registries have generated important information concerning the clinical characteristics of patients with AHFS and their prognosis. Most patients with AHFS present either with normal systolic blood pressure or elevated blood pressure. Patients who present with elevated systolic blood pressure usually have pulmonary congestion, a relatively preserved left ventricular ejection fraction (LVEF), are often elderly women, and their symptoms develop typically and abruptly. Patients with normal systolic blood pressure present with systemic congestion, reduced LVEF, are usually younger with a history of chronic HF, and have symptoms that develop gradually over days or weeks. In addition to the abnormal hemodynamics (increase in pulmonary capillary wedge pressure and/or decrease in cardiac output) that characterize patients with AHFS, myocardial injury, which may be related to a decrease in coronary perfusion and/or further activation of neurohormones and renal dysfunction, probably contributes to short-term and post-discharge cardiac events. Patients with AHFS also have significant cardiac and noncardiac underlying conditions that contribute to the pathogenesis of AHFS, including coronary artery disease (ischemia, hibernating myocardium, and endothelial dysfunction), hypertension, atrial fibrillation, and type 2 diabetes mellitus. Therefore, the targets of therapy for AHFS should be not only to improve symptoms and hemodynamics but also to preserve or improve renal function, prevent myocardial damage, modulate neurohumoral and inflammatory activation, and to manage other comorbidities that may cause and/or contribute to the progression of this syndrome.

  • Early pharmacological treatment of acute heart failure syndromes: A systematic review of clinical trials
  • 2007
  • Ingår i: Acute cardiac care. - 1748-2941. ; 9:1, s. 10-21
  • Tidskriftsartikel (refereegranskat)abstract
    • Context: Acute Heart Failure Syndromes (AHFS) is a common admission diagnosis associated with high mortality and hospital readmissions. Given the mixed results of recent clinical trials, the early management of AHFS remains controversial. Objective: To review the recent evidence regarding current and investigational therapies for the early management of AHFS. Data Sources: A systematic search of peer-reviewed publications was performed on MEDLINE and EMBASE from January 1990 to August 2006. The results of unpublished or ongoing trials were obtained from presentations at national and international meetings and pharmaceutical industry releases. Bibliographies from these references were also reviewed, as were additional articles identified by content experts. Study Selection and Data Extraction: Criteria used for study selection were controlled study design, relevance to clinicians and validity based on venue of publication and power analysis. Data Synthesis: Although all current intravenous therapies for the early management of AHFS appear to improve hemodynamics, this may not always translate into short-term clinical benefit. Conclusion: The results of the trials conducted to date in AHFS have generally been disappointing. There is, therefore, an unmet need for new therapeutic approaches for the early management of AHFS that may improve the short-term and long-term outcomes.

  • Incidence and predictors of hyperkalemia in patients with heart failure: an analysis of the CHARM Program
  • 2007
  • Ingår i: J Am Coll Cardiol. - 1558-3597. ; 50:20, s. 1959-66
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: We explored the incidence and predictors of hyperkalemia in a broad population of heart failure patients. BACKGROUND: When used in optimal doses to treat patients with heart failure, renin-angiotensin-aldosterone system (RAAS) inhibitors improve clinical outcomes but can cause hyperkalemia. METHODS: Participants in the CHARM (Candesartan in Heart Failure-Assessment of Reduction in Mortality and Morbidity) (n = 7,599) Program were randomized to standard heart failure therapy plus candesartan or placebo, titrated as tolerated to a target of 32 mg once daily with recommended monitoring of serum potassium and creatinine. We assessed the incidence and predictors of hyperkalemia associated with dose reduction, study drug discontinuation, hospitalization, or death over the median 3.2 years of follow-up. RESULTS: Independent of treatment assignment, the risk of hyperkalemia increased with age > or =75 years, male gender, diabetes, creatinine > or =2.0 mg/dl, K+ > or =5.0 mmol/l, and background use of angiotensin-converting enzyme inhibitors or spironolactone. Candesartan increased the rate of aggregate hyperkalemia from 1.8% to 5.2% (difference 3.4%, p < 0.0001) and serious hyperkalemia (associated with death or hospitalization) from 1.1% to 1.8% (difference 0.7%, p < 0.001), with hyperkalemia associated with death reported in 2 (0.05%) candesartan patients and 1 (0.03%) placebo patient. The benefit of candesartan in reducing cardiovascular death or heart failure hospitalization (relative risk reduction 16%, p < 0.0001) was uniform in these subgroups, as was the incremental risk of hyperkalemia. CONCLUSIONS: The risk of hyperkalemia is increased in symptomatic heart failure patients with advanced age, male gender, baseline hyperkalemia, renal failure, diabetes, or combined RAAS blockade. Although these groups derive incremental clinical benefit from candesartan, careful surveillance of serum potassium and creatinine is particularly important.

  • Breaking the vicious circle of fatigue in patients with chronic heart failure
  • 2007
  • Ingår i: Qualitative health research. - : SAGE Publications. - 1049-7323 .- 1552-7557. ; 17:8, s. 1020-7
  • Tidskriftsartikel (refereegranskat)abstract
    • Fatigue is a common symptom in patients with chronic heart failure (CHF). Characteristics of the experience and consequences of fatigue might be unique in these patients. The authors interviewed 15 patients with CHF and analyzed focused online observations of the content discussed in an Internet patient discussion group concerning CHF using grounded theory. The results suggest that fatigue is a circular process in which the consequences of fatigue further exaggerate the experience. However, fatigue could be alleviated by restorative activities. The bodily experience of fatigue was defined as lacking strength and energy and feeling sleepy. Patients reported the mental aspects of fatigue as demoralizing and that they frequently experienced intellectual deficiency. Fatigue leads to sacrificing, which was manifested as refraining, denying oneself, and being isolated. The restoring activities included the categories involuntarily attentive, socially interactive, and mentally absorbed. Interventions aimed to relieve fatigue should focus on restorative activities.
