On target to dual block RAS?

Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers are thought to possess cardioprotective, cerebroprotective, and nephroprotective properties. Both classes of agents can prevent or reverse endothelial dysfunction and atherosclerosis, thereby potentially reducing the risk of cardiovascular events. Such a reduction has been shown with angiotensin-converting enzyme inhibitors in patients with coronary artery disease, but no such data are scarce with angiotensin receptor blockers (Valsartan in Acute Myocardial Infarction study). Both angiotensin-converting enzyme inhibitors and angiotensin receptor blockers have been shown to reduce damage in target organs, such as the heart and kidney, and to decrease cardiovascular mortality and morbidity in patients with congestive heart failure. These drugs (especially angiotensin receptor blockers) may successfully prevent atrial fibrillation and play a protective role in metabolic syndrome. In some clinical settings, combined therapy angiotensin-converting enzyme inhibitors with angiotensin receptor blocker (double blockade of the renin-angiotensin- aldosterone system) may appear the most effective.
