Abstract:
Prognosis in congestive heart failure is directly linked to neurohormonal activation. Angiotensin II through the activation of the renin angiotensin aldosterone system has been the principal focus therapy over the last 2 decades. New agents that target selective blockade of the angiotensin II receptor have been introduced in clinical trials for the treatment of heart failure. Aldosterone has been identified as a critically important neurohormone with direct detrimental effects on the myocardium. Aldosterone antagonists have been used in clinical trials to improve mortality in patients with chronic heart failure.
