Large observational studies, small prospective studies and post-hoc analyses of randomised clinical trials have suggested that statins could be beneficial in patients with chronic heart failure. However, previous studies have been methodologically weak. We investigated the efficacy and safety of the statin rosuvastatin in patients with heart failure.
We undertook a randomised, double-blind, placebo-controlled trial in 326 cardiology and 31 internal medicine centres in Italy. We enrolled patients aged 18 years or older with chronic heart failure of New York Heart Association class II-IV, irrespective of cause and left ventricular ejection fraction, and randomly assigned them to rosuvastatin 10 mg daily (n=2285) or placebo (n=2289) by a concealed, computerised telephone randomisation system. Patients were followed up for a median of 3.9 years (IQR 3.0-4.4). Primary endpoints were time to death, and time to death or admission to hospital for cardiovascular reasons. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00336336.
We analysed all randomised patients. 657 (29%) patients died from any cause in the rosuvastatin group and 644 (28%) in the placebo group (adjusted hazard ratio [HR] 1.00 [95.5% CI 0.898-1.122], p=0.943). 1305 (57%) patients in the rosuvastatin group and 1283 (56%) in the placebo group died or were admitted to hospital for cardiovascular reasons (adjusted HR 1.01 [99% CI 0.908-1.112], p=0.903). In both groups, gastrointestinal disorders were the most frequent adverse reaction (34 [1%] rosuvastatin group vs 44 [2%] placebo group).
Rosuvastatin 10 mg daily did not affect clinical outcomes in patients with chronic heart failure of any cause, in whom the drug was safe.
大型观察性研究、小型前瞻性研究以及随机临床试验的事后分析表明,他汀类药物可能对慢性心力衰竭患者有益。然而,既往研究在方法学上存在缺陷。我们调查了他汀类药物瑞舒伐他汀对心力衰竭患者的疗效和安全性。
我们在意大利的326个心脏病学中心和31个内科中心进行了一项随机、双盲、安慰剂对照试验。我们纳入了年龄在18岁及以上、患有纽约心脏协会II-IV级慢性心力衰竭的患者,无论病因和左心室射血分数如何,并通过隐蔽的计算机电话随机系统将他们随机分配至每日服用10 mg瑞舒伐他汀组(n = 2285)或安慰剂组(n = 2289)。患者的中位随访时间为3.9年(四分位间距3.0 - 4.4年)。主要终点为死亡时间以及因心血管原因死亡或住院的时间。分析采用意向性分析。本研究已在ClinicalTrials.gov注册,注册号为NCT00336336。
我们分析了所有随机分组的患者。瑞舒伐他汀组有657例(29%)患者因任何原因死亡,安慰剂组有644例(28%)(校正风险比[HR] 1.00 [95.5% CI 0.898 - 1.122],p = 0.943)。瑞舒伐他汀组有1305例(57%)患者死亡或因心血管原因住院,安慰剂组有1283例(56%)(校正HR 1.01 [99% CI 0.908 - 1.112],p = 0.903)。在两组中,胃肠道疾病是最常见的不良反应(瑞舒伐他汀组34例[1%] vs安慰剂组44例[2%])。
每日服用10 mg瑞舒伐他汀对任何病因的慢性心力衰竭患者的临床结局无影响,且该药物在这些患者中是安全的。
