  • Title: Aldosterone antagonists in congestive heart failure.
    Author: Soberman J, Chafin CC, Weber KT.
    Journal: Curr Opin Investig Drugs; 2002 Jul; 3(7):1024-8. PubMed ID: 12186262.
    Abstract:
    The role of aldosterone in the pathophysiology of congestive heart failure (CHF) has long been recognized. The recent RALES (Randomized Aldactone Evaluation Study) trial demonstrated early reduction in morbidity and mortality using spironolactone, an aldosterone receptor antagonist, in combination with angiotensin converting enzyme (ACE) inhibitor and loop diuretic, in patients with heart failure. This effect of spironolactone highlighted the importance of understanding the contributions of the renin-angiotensin-aldosterone system (RAAS) in the progression of CHF, and increased interest in the use of aldosterone antagonists. While ACE inhibitors have had the largest impact on adverse events in CHF, numerous studies have shown that these drugs fail to completely suppress aldosterone. Blocking the effects of residual aldosterone has now been demonstrated to affect prognosis in these patients. This review will discuss the role of aldosterone in the pathophysiology of CHF, with an emphasis on both known and potential therapeutic benefits of aldosterone antagonism.
