- AIMS: This report describes the baseline characteristics of patients in the Reduction of Events with Darbepoetin alfa in Heart Failure trial (RED-HF) which is testing the hypothesis that anaemia correction with darbepoetin alfa will reduce the composite endpoint of death from any cause or hospital admission for worsening heart failure, and improve other outcomes. METHODS AND RESULTS: Key demographic, clinical, and laboratory findings, along with baseline treatment, are reported and compared with those of patients in other recent clinical trials in heart failure. Compared with other recent trials, RED-HF enrolled more elderly [mean age 70 (SD 11.4) years], female (41%), and black (9%) patients. RED-HF patients more often had diabetes (46%) and renal impairment (72% had an estimated glomerular filtration rate <60 mL/min/1.73 m(2)). Patients in RED-HF had heart failure of longer duration [5.3 (5.4) years], worse NYHA class (35% II, 63% III, and 2% IV), and more signs of congestion. Mean EF was 30% (6.8%). RED-HF patients were well treated at randomization, and pharmacological therapy at baseline was broadly similar to that of other recent trials, taking account of study-specific inclusion/exclusion criteria. Median (interquartile range) haemoglobin at baseline was 112 (106-117) g/L. CONCLUSION: The anaemic patients enrolled in RED-HF were older, moderately to markedly symptomatic, and had extensive co-morbidity.

- Background Patients with systolic heart failure and anemia have worse symptoms, functional capacity, and outcomes than those without anemia. We evaluated the effects of darbepoetin alfa on clinical outcomes in patients with systolic heart failure and anemia. Methods In this randomized, double-blind trial, we assigned 2278 patients with systolic heart failure and mild-to-moderate anemia (hemoglobin level, 9.0 to 12.0 g per deciliter) to receive either darbepoetin alfa (to achieve a hemoglobin target of 13 g per deciliter) or placebo. The primary outcome was a composite of death from any cause or hospitalization for worsening heart failure. Results The primary outcome occurred in 576 of 1136 patients (50.7%) in the darbepoetin alfa group and 565 of 1142 patients (49.5%) in the placebo group (hazard ratio in the darbepoetin alfa group, 1.01; 95% confidence interval, 0.90 to 1.13; P=0.87). There was no significant between-group difference in any of the secondary outcomes. The neutral effect of darbepoetin alfa was consistent across all prespecified subgroups. Fatal or nonfatal stroke occurred in 42 patients (3.7%) in the darbepoetin alfa group and 31 patients (2.7%) in the placebo group (P=0.23). Thromboembolic adverse events were reported in 153 patients (13.5%) in the darbepoetin alfa group and 114 patients (10.0%) in the placebo group (P=0.01). Cancer-related adverse events were similar in the two study groups. Conclusions Treatment with darbepoetin alfa did not improve clinical outcomes in patients with systolic heart failure and mild-to-moderate anemia. Our findings do not support the use of darbepoetin alfa in these patients. (Funded by Amgen; RED-HF ClinicalTrials.gov number, NCT00358215 .).

- Mineralocorticoid receptor antagonists (MRAs) improve survival and reduce morbidity in patients with heart failure, reduced ejection fraction (HF-REF), and mild-to-severe symptoms, and in patients with left ventricular systolic dysfunction and heart failure after acute myocardial infarction. These clinical benefits are observed in addition to those of angiotensin converting enzyme inhibitors or angiotensin receptor blockers and beta-blockers. The morbidity and mortality benefits of MRAs may be mediated by several proposed actions, including antifibrotic mechanisms that slow heart failure progression, prevent or reverse cardiac remodelling, or reduce arrhythmogenesis. Both eplerenone and spironolactone have demonstrated survival benefits in individual clinical trials. Pharmacologic differences exist between the drugs, which may be relevant for therapeutic decision making in individual patients. Although serious hyperkalaemia events were reported in the major MRA clinical trials, these risks can be mitigated through appropriate patient selection, dose selection, patient education, monitoring, and follow-up. When used appropriately, MRAs significantly improve outcomes across the spectrum of patients with HF-REF.

- AIMS: Abnormal liver function tests (LFTs) are common in ambulatory heart failure (HF). The aim of this study was to characterize abnormal LFTs during index hospitalization. METHODS AND RESULTS: A post-hoc analysis was carried out of the placebo group of the EVEREST (Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with Tolvaptan) trial, which enrolled patients hospitalized for HF with an ejection fraction (EF) 34 IU/L), alanine transaminase (ALT, >34 IU/L), alkaline phosphatase (AP, >123 IU/L),gamma-glutamyl transferase (GGT, >50 IU/L), and total bilirubin (T Bili, >1.2 mg/dL) were measured at baseline, discharge/day 7, and post-discharge. Co-primary endpoints were all-cause mortality (ACM) and cardiovascular mortality or first HF hospitalization (CVM + HFH). Study participants had a mean age of 65.6 +/-12.0 years, were mostly male, reported high prevalences of medical co-morbidities, and were well treated with evidence-based therapies. Baseline LFT abnormalities were common (ALB 17%, AST 21%, ALT 21%, AP 23%, GGT 62%, and T Bili 26%). Abnormal T Bili was the only marker to decrease substantially from baseline (26%) to discharge/day 7 (19%). All LFTs, except AP, improved post-discharge. Lower baseline ALB and elevated T Bili were associated with higher rates of ACM, and in-hospital decreases in ALB and increases in T Bili were associated with higher rates of both ACM and CVM + HFH. CONCLUSION: LFT abnormalities are common during hospitalization for HF in patients with reduced EF and were persistent at discharge. Baseline and in-hospital changes in ALB and T Bili provide additional prognostic value.

- BACKGROUND: Patients with decompensated heart failure, volume overload, and hyponatremia are challenging to manage. Relatively little has been documented regarding the clinical course of these patients during standard in-hospital management or with vasopressin antagonism. METHODS AND RESULTS: The Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study With Tolvaptan database was examined to assess the short-term clinical course of patients hospitalized with heart failure and hyponatremia and the effect of tolvaptan on outcomes. In the placebo group, patients with hyponatremia (serum Na(+) <135mEq/L; n = 232), compared with those with normonatremia at baseline (n = 1785), had less relief of dyspnea despite receiving higher doses of diuretics (59.2% vs 69.2% improved; P < .01) and worse long-term outcomes. In the hyponatremia subgroup from the entire trial cohort (n = 475), tolvaptan was associated with greater likelihood of normalization of serum sodium than placebo (58% vs 20% and 64% vs 29% for day 1 and discharge, respectively; P < .001 for both comparisons), greater weight reduction at day 1 and discharge (0.7 kg and 0.8 kg differences, respectively; P < .001 and P = .008), and greater relief of dyspnea (P = .03). Among all hyponatremic patients, there was no effect of tolvaptan on long-term outcomes compared with placebo. In patients with pronounced hyponatremia (<130 mEq/L; n = 92), tolvaptan was associated with reduced cardiovascular morbidity and mortality after discharge (P = .04). CONCLUSIONS: In patients with decompensated heart failure and hyponatremia, standard therapy is associated with less weight loss and dyspnea relief, and unfavorable longer-term outcomes compared to those with normonatremia. Tolvaptan is associated with more favorable in-hospital effects and, possibly, long-term outcomes in patients with severe hyponatremia.

- To evaluate how recommendations of European guidelines regarding pharmacological and non-pharmacological treatments for heart failure (HF) are adopted in clinical practice. less thanbrgreater than less thanbrgreater thanThe ESC-HF Long-Term Registry is a prospective, observational study conducted in 211 Cardiology Centres of 21 European and Mediterranean countries, members of the European Society of Cardiology (ESC). From May 2011 to April 2013, a total of 12 440 patients were enrolled, 40.5 with acute HF and 59.5 with chronic HF. Intravenous treatments for acute HF were heterogeneously administered, irrespective of guideline recommendations. In chronic HF, with reduced EF, reninangiotensin system (RAS) blockers, beta-blockers, and mineralocorticoid antagonists (MRAs) were used in 92.2, 92.7, and 67.0 of patients, respectively. When reasons for non-adherence were considered, the real rate of undertreatment accounted for 3.2, 2.3, and 5.4 of the cases, respectively. About 30 of patients received the target dosage of these drugs, but a documented reason for not achieving the target dosage was reported in almost two-thirds of them. The more relevant reasons for non-implantation of a device, when clinically indicated, were related to doctor uncertainties on the indication, patient refusal, or logistical/cost issues. less thanbrgreater than less thanbrgreater thanThis pan-European registry shows that, while in patients with acute HF, a large heterogeneity of treatments exists, drug treatment of chronic HF can be considered largely adherent to recommendations of current guidelines, when the reasons for non-adherence are taken into account. Observations regarding the real possibility to adhere fully to current guidelines in daily clinical practice should be seriously considered when clinical practice guidelines have to be written.
