Global variation in clinical profile, management, and post-discharge outcomes among patients hospitalized for worsening chronic heart failure: findings from the ASTRONAUT trial

Résumé

AIMS: This study sought to investigate regional variation in clinical characteristics, therapy utilization, and post-discharge outcomes among patients hospitalized for heart failure (HHF) enrolled in the multinational ASTRONAUT (Aliskiren Trial on Acute Heart Failure Outcomes) trial. METHODS AND RESULTS: The ASTRONAUT trial randomized 1615 HHF patients with ejection fraction ≤40% to aliskiren or placebo. Enrolled patients were from Eastern Europe (n = 495, 30.7%), Asia/Pacific (n = 439, 27.2%), Western Europe (n = 395, 24.5%), Latin America (n = 163, 10.1%), and North America (n = 123, 7.6%). Marked differences were seen across geographic regions in terms of baseline demographics, vital signs, laboratory tests, co-morbidity burden, and use of guideline-recommended therapies. All-cause death at 12 months ranged from 7.3% in North America to 26.7% in Asia/Pacific, with differences largely driven by sudden cardiac death. Rates of repeat HHF at 12 months ranged from 22.7% in Latin America to 43.9% in North America. After adjustment for patient characteristics, region was an independent predictor of death at 12 months, with highest risk in Asia/Pacific (hazard ratio 3.04, 95% confidence interval 1.47-6.29, compared with North America) and lowest risk in North America and Western Europe. There was no association between region and the composite of cardiovascular mortality or HHF. CONCLUSION: For patients enrolled in this HHF trial, baseline characteristics and risk of death differed markedly by geographic region. Rates of death and repeat HHF demonstrated a general inverse relationship. Global differences in patient characteristics and outcomes should be accounted for when designing future HHF clinical trials.
