- BACKGROUND: Nesiritide is approved in the United States for early relief of dyspnea in patients with acute heart failure. Previous meta-analyses have raised questions regarding renal toxicity and the mortality associated with this agent. METHODS: We randomly assigned 7141 patients who were hospitalized with acute heart failure to receive either nesiritide or placebo for 24 to 168 hours in addition to standard care. Coprimary end points were the change in dyspnea at 6 and 24 hours, as measured on a 7-point Likert scale, and the composite end point of rehospitalization for heart failure or death within 30 days. RESULTS: Patients randomly assigned to nesiritide, as compared with those assigned to placebo, more frequently reported markedly or moderately improved dyspnea at 6 hours (44.5% vs. 42.1%, P=0.03) and 24 hours (68.2% vs. 66.1%, P=0.007), but the prespecified level for significance (P

- AIMS: It is unknown whether there is an interaction between aspirin and angiotensin receptor blockers on outcomes in patients with heart failure (HF). METHODS AND RESULTS: The efficacy and safety of candesartan vs. placebo was assessed in 7599 patients with symptomatic HF and reduced or preserved left ventricular ejection fraction enrolled in the CHARM programme according to baseline aspirin use. Patients were randomized to candesartan or matching placebo and were followed for a median of 38 months. Aspirin was used in 4246 (55.9%) of patients at baseline. When compared with placebo, candesartan use was associated with lower event rates for cardiovascular (CV) death or HF hospitalization (primary outcome) in both the aspirin group (28 vs. 31.9%, HR 0.81, 95% CI 0.72-0.90) and non-aspirin group (33 vs. 38%, HR 0.81, 95% CI 0.72-0.91). Baseline aspirin use did not modify the effectiveness of candesartan in reducing the risk of CV death or HF hospitalization in CHARM overall (P = 0.64) or in the CHARM individual trials. In addition, there was no significant interaction between aspirin therapy and candesartan in terms of discontinuation of study drug due to adverse reactions (P = 0.72). CONCLUSION: There appears to be no significant modification of the benefit of candesartan on CV mortality and morbidity outcomes or safety by concomitant use of aspirin in patients with chronic HF.
