Selective aldosterone blockade with eplerenone in patients with congestive heart failure

In the Eplerenone Postacute Myocardial Infarction Heart Failure Efficacy and Survival Study (EPHESUS) the effects of selective aldosterone blockade with eplerenone on cardiovascular mortality and morbidity were studied in patients with reduced left ventricular function postacute myocardial infarction. Data from this landmark study suggest that eplerenone can be an effective addition to the therapy of patients with congestive heart failure and is associated with fewer side effects than spironolactone. Further research is warranted concerning the possible benefits of this new agent in disease states other than congestive heart failure in which an activated renin-angiotensin-aldosterone system system has been implicated.
