【 摘 要 】

Background - In the Eplerenone Post - Acute Myocardial Infarction Heart Failure Efficacy and Survival Study (EPHE-SUS), aldosterone blockade with eplerenone decreased mortality in patients with left ventricular systolic dysfunction and heart failure after acute myocardial infarction. The present study was performed to evaluate the cost-effectiveness of eplerenone compared with placebo in these patients. Methods and Results - A total of 6632 patients with left ventricular systolic dysfunction and heart failure after acute myocardial infarction were randomized to eplerenone or placebo and followed up for a mean of 16 months. The coprimary end points were all-cause mortality and the composite of cardiovascular mortality/cardiovascular hospitalization. The evaluation of resource use included hospitalizations, outpatient services, and medications. Eplerenone was priced at the average wholesale price, $3.60 per day. Survival beyond the trial period was estimated from data from the Framingham Heart Study, the Saskatchewan Health database, and the Worcester Heart Attack Registry. The incremental cost-effectiveness of eplerenone in cost per life-year and quality-adjusted life-year gained compared with placebo was estimated. The number of life-years gained with eplerenone was 0.1014 based on Framingham (95 % CI, 0.0306 to 0.1740), 0.0636 with Saskatchewan (95 % CI, 0.0229 to 0.1038), and 0.1337 with Worcester (95% CI, 0.0438 to 0.2252) data. Cost was $ 1391 higher over the trial period in the eplerenone arm ( 95% CI, 656 to 2165) because of drug cost. The incremental cost-effectiveness ratio was $ 13718 per life-year gained with Framingham (96.7 % under $ 50 000 per life-year gained), $ 21 876 with Saskatchewan, and $ 10 402 with Worcester. Conclusions - Eplerenone compared with placebo in the treatment of heart failure after acute myocardial infarction is effective in reducing mortality and is cost-effective in increasing years of life by commonly used criteria.
