Renin-angiotensin system as a potential target for the treatment with heart failure: ACE inhibitors,angiotensin-II receptor blockers and aldosterone antagonists

Recent experimental studies and clinical trials have revealed that the modulation of either systemic or regional(cardiovascular) renin-angiotensin systems(RAS) is one of the potential targets to prevent the progression of heart failure. Either ACE inhibitor, angiotensin-II receptor blocker or aldosterone antagonist differently block RAS. Many clinical trials told us that each of them improves heart failure and might promise the better prognosis. Now, some experimental studies are encouraging us to test the comparative effects or the effects in combination of them. Here we will summarize the current outcomes from the experimental and clinical studies, and discuss the future direction.
