- 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.

- In large-scale randomized trials and their meta-analyses, beta-adrenergic blockers and angiotensin-converting enzyme inhibitors provide statistically significant and clinically important additive mortality and morbidity benefits in the treatment of heart failure. The CHARM trials were designed to test whether the angiotensin-receptor blocker candesartan would provide statistically significant and clinically important additive mortality and morbidity benefits to patients with heart failure as an alternative or in addition to angiotensin-converting enzyme inhibitors. CHARM demonstrated that an angiotensin-receptor blocker at a proven dose is an effective and safe therapy as an alternative or in addition to angiotensin-converting enzyme inhibitors in patients with heart failure, 55% of whom were receiving beta-adrenergic blockers. These benefits include reductions in cardiovascular mortality rate as well as in hospitalization for heart failure. Such patients have a 50% mortality rate at 5 years, and heart failure is the leading cause of hospitalization for patients 65 years of age and older.

- BACKGROUND: In individuals without known cardiovascular disease, elevated body mass index (BMI) (weight/height2) is associated with an increased risk of death. However, in patients with certain specific chronic diseases, including heart failure, low BMI has been associated with increased mortality. METHODS AND RESULTS: We examined the influence of BMI on prognosis using Cox proportional hazards models in 7599 patients (mean age, 65 years; 35% women) with symptomatic heart failure (New York Heart Association class II to IV) and a broad spectrum of left ventricular ejection fractions (mean, 39%) in the Candesartan in Heart failure: Assessment of Reduction in Mortality and morbidity (CHARM) program. During a median follow-up of 37.7 months, 1831 patients died. After adjustment for potential confounders, compared with patients with BMI between 30 and 34.9, patients in lower BMI categories had a graded increase in the risk of death. The hazard ratios (95% confidence intervals) were 1.22 (1.06 to 1.41), 1.46 (1.24 to 1.71), and 1.69 (1.43 to 2.01) among those with BMI of 25 to 29.9, 22.5 to 24.9, and < 22.5, respectively. The increase in risk of death among patients with BMI > or = 35 was not statistically significant (hazard ratio, 1.17; 95% confidence interval, 0.95 to 1.43). The association between BMI and mortality was not altered by age, smoking status, or left ventricular ejection fraction (P for interaction >0.20). However, lower BMI was associated with a greater risk of all-cause death in patients without edema but not in patients with edema (P for interaction <0.0001). Lower BMI was associated with a greater risk of cardiovascular death and noncardiovascular death. Baseline BMI did not influence the risk of hospitalization for worsening heart failure or due to all causes. CONCLUSIONS: In patients with symptomatic heart failure and either reduced or preserved left ventricular systolic function, underweight or low BMI was associated with increased mortality, primarily in patients without evidence of fluid overload (edema).

- BACKGROUND: Most patients suspected of having heart failure (HF) will get a 12-lead electrocardiogram (ECG) but its utility for excluding HF or assisting in its management has rarely been investigated. METHODS: The EuroHeart Failure survey identified 11,327 patients hospitalised with a suspected diagnosis of HF from 115 hospitals in 24 countries. ECGs were obtained from 9315 patients, of whom 5934 had cardiac imaging tests. The utility of the ECG was assessed for excluding or diagnosing major structural heart disease (MSHD) or major left ventricular systolic dysfunction (MLVSD) and for therapeutic decision making. FINDINGS: MSHD was present in 70% and MLVSD in 54% of patients overall but in only 21% and 5%, respectively, if the ECG was entirely normal. However, <2% of patients had a normal ECG. No single ECG characteristic identified a probability <25% of MSHD or <20% of MLVSD. Patients with QRS width >/=120 ms or anterior pathological Q-waves had a probability >80% of MSHD and >70% of MLVSD. Diagnostic models suggested that electrocardiographic criteria alone were not accurate for the diagnosis or exclusion of important heart disease in this population. However, 2468 patients (42%) had an electrocardiographic finding that should be used to guide the choice of therapy. CONCLUSIONS: A normal ECG is rare in patients with suspected HF but has limited diagnostic value in this setting. The ECG has an important role in guiding therapy.

- AIMS: Here, the aim is to study the management of octogenarians hospitalized for heart failure in Euro Heart Failure Survey I. Heart Failure (HF) is common in older people and associated with poor outcome. METHODS AND RESULTS: We compared clinical characteristics, treatment, and short-term outcomes in 2780 octogenarians (group A, median age 85 years) and in 7912 younger patients (group B, median age 69 years) enrolled in the Euro Heart Failure Survey I. There were 37% males in group A vs. 59% in group B (P < 0.001). Co-morbidities were more common in group A. Ejection fraction was measured only in 38% in group A vs. 65% in group B (P < 0.001) and when measured was preserved in 50 vs. 40% (P < 0.001). In-hospital and 12 weeks follow-up mortality were, respectively, 13 vs. 5% (P < 0.001) and 12 vs. 6% (P < 0.001) in groups A and B. Acute cardiac conditions and co-morbidity predicted mortality, whereas the use of angiotensin-converting enzyme inhibitor (ACE-I) and beta-blockers was associated with a better outcome. ACE-I and beta-blockers were used in 50 vs. 66% (P < 0.001) and 24 vs. 42% (P < 0.001) in groups A and B, respectively, whereas diuretics, digitalis, and nitrates were more commonly used in octogenarians. CONCLUSION: Preserved systolic function, multiple co-morbidities, and high mortality are observed in octogenarians with HF. In these patients, cardiac function is assessed in only a minority and treatments known to improve prognosis in younger patients under-utilized. Overall, the management of octogenarians with HF does not follow international guidelines.

- CONTEXT: Vasopressin mediates fluid retention in heart failure. Tolvaptan, a vasopressin V2 receptor blocker, shows promise for management of heart failure. OBJECTIVE: To investigate the effects of tolvaptan initiated in patients hospitalized with heart failure. DESIGN, SETTING, AND PARTICIPANTS: The Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study With Tolvaptan (EVEREST), an event-driven, randomized, double-blind, placebo-controlled study. The outcome trial comprised 4133 patients within 2 short-term clinical status studies, who were hospitalized with heart failure, randomized at 359 North American, South American, and European sites between October 7, 2003, and February 3, 2006, and followed up during long-term treatment. INTERVENTION: Within 48 hours of admission, patients were randomly assigned to receive oral tolvaptan, 30 mg once per day (n = 2072), or placebo (n = 2061) for a minimum of 60 days, in addition to standard therapy. MAIN OUTCOME MEASURES: Dual primary end points were all-cause mortality (superiority and noninferiority) and cardiovascular death or hospitalization for heart failure (superiority only). Secondary end points included changes in dyspnea, body weight, and edema. RESULTS: During a median follow-up of 9.9 months, 537 patients (25.9%) in the tolvaptan group and 543 (26.3%) in the placebo group died (hazard ratio, 0.98; 95% confidence interval [CI], 0.87-1.11; P = .68). The upper confidence limit for the mortality difference was within the prespecified noninferiority margin of 1.25 (P<.001). The composite of cardiovascular death or hospitalization for heart failure occurred in 871 tolvaptan group patients (42.0%) and 829 placebo group patients (40.2%; hazard ratio, 1.04; 95% CI, 0.95-1.14; P = .55). Secondary end points of cardiovascular mortality, cardiovascular death or hospitalization, and worsening heart failure were also not different. Tolvaptan significantly improved secondary end points of day 1 patient-assessed dyspnea, day 1 body weight, and day 7 edema. In patients with hyponatremia, serum sodium levels significantly increased. The Kansas City Cardiomyopathy Questionnaire overall summary score was not improved at outpatient week 1, but body weight and serum sodium effects persisted long after discharge. Tolvaptan caused increased thirst and dry mouth, but frequencies of major adverse events were similar in the 2 groups. CONCLUSION: Tolvaptan initiated for acute treatment of patients hospitalized with heart failure had no effect on long-term mortality or heart failure-related morbidity.

- BACKGROUND: Treatment of heart failure (HF) due to left ventricular systolic dysfunction (LVSD) is effective, but many patients are not treated in accordance with guidelines. This may reflect a lack of adequate organisation of care or co-morbidity contra-indicating therapy. AIMS: To evaluate the effect of co-morbidities on the prescription of neurohormonal antagonists for HF. METHODS AND RESULTS: The EuroHeart Failure Survey identified 10,701 patients with suspected or confirmed HF during 2000 and 2001, 64% of whom had an imaging test and 3658 had documented LVSD. This last group constitutes the focus of this report. Renal dysfunction was associated with lower prescription of ACE inhibitors at discharge (74% vs. 83%, p<0.001). Beta-blockers were less often used in patients with respiratory disease (32% vs. 53%, p<0.001). Co-morbidity did not appear to affect the use of spironolactone. There were few important international differences in uptake of key therapies amongst European countries with widely differing cultures and economic status. CONCLUSIONS: Guidelines appear successful in creating a relatively uniform approach to the treatment for HF due to LVSD in diverse medical cultures. Relevant co-morbidity seems to be responsible for a substantial reduction in the prescription of ACE inhibitors and beta-blockers. However, whilst co-morbidity indicates the need for greater caution, it is often not a valid contra-indication to life-saving therapy.

- Advice on lifestyle, diet, vaccination, and therapy are part of the standard management of heart failure (HF). However, there is little information on whether patients with HF recall receiving such recommendations and, if so, whether they report following them. We obtained information on the recall of and adherence to nonpharmacologic advice from patients enrolled in the EuroHeart Failure Survey. This article focuses on 2,331 patients who had a clinical diagnosis of HF during the index admission and attended an interview 12 weeks after discharge. Their mean age was 67 +/- 12 years and 38% were women. Patients recalled receiving 4.1 +/- 2.7 items of advice with higher rates in Central Europe and the Mediterranean region. Recall of dietary advice (cholesterol or fat intake, 63%; dietary salt, 60%) was higher than for some other interventions (influenza vaccination, 36%; avoidance of nonsteroidal anti-inflammatory drugs, 17%). Among those who recalled the advice, a substantial proportion indicated that they did not follow advice completely (cholesterol and fat intake, 61%; dietary salt, 63%; influenza vaccination, 75%; avoidance of nonsteroidal anti-inflammatory drugs, 80%), although few patients indicated they ignored the advice completely. Patients who recalled >4 items versus < or =4 items of advice were younger and more often received angiotensin-converting enzyme inhibitors (71% vs 62%), beta-blockers (51% vs 38%), and spironolactone (25% vs 21%). In conclusion, after hospitalization for HF, many patients do not recall nonpharmacologic advice. In addition, a substantial proportion of those who recall the advice follow it incompletely. Younger age and prescription of appropriate pharmacologic treatment are associated with higher rates of recall and implementation.

- BACKGROUND: There are limited data on recall and implementation of lifestyle advice in patients with heart failure (HF). AIM: To investigate what advice patients with HF recall being given, and whether they report following the advice they remember. METHODS AND RESULTS: 3261 patients with suspected HF participating in the EuroHeart Failure Survey were interviewed by a health professional 12 weeks after hospital discharge. Patients recalled receiving 46% of pre-specified items of advice and 67% reported that they followed these completely. Both recall (53%) and implementation (71%) was best in patients with left ventricular systolic dysfunction (LVSD). In multivariate analysis, younger age, male sex, patient awareness of the condition and patients reporting that they received a clear explanation of the diagnosis by a health professional, all factors associated with having LVSD, were the strongest predictors of recall. CONCLUSIONS: Recall of and adherence to advice by patients with HF in this large European cross-sectional survey was disappointing. Responsibility for patient education lies with health professionals who should ensure that patients receive and understand advice, and are able to recall and follow it. A greater awareness of the issues surrounding lifestyle advice and more evidence supporting its value could improve patient care.

- BACKGROUND: Limited comparative studies assessing the health-related quality of life (HRQL) in heart failure (HF) patients with preserved vs. low ejection fraction (LVEF) have been disparate. AIMS: The aims of this study were a) to characterize HRQL in a large population of HF patients with preserved and low LVEF and b) to determine the factors associated with worse HRQL. METHODS: Patients with symptomatic HF (NYHA Class II-IV) enrolled in the Candesartan in Heart Failure: Assessment of Reduction in Mortality and Morbidity (CHARM) HRQL study completed the Minnesota Living with Heart Failure questionnaire at randomization. Patients were stratified into 2 HF cohorts: preserved LVEF (>40%) and low LVEF (
