ACEI or ARB for LVSD

What It Means
The percentage of patients with Acute Myocardial Infarction with left ventricular systolic dysfunction (LVSD) who were prescribed with either an ACE (angiotensin converting enzyme inhibitor) or an ARB (Angiotensin receptor blocker) at hospital discharge.

Why It Is Important
Clinical evidence shows that the use of an ACE or an ARB after a heart attack on the front side of the heart improves long-term survival and provides greater benefit to the patient. ACE inhibitors and ARBs work by limiting the effects of a hormone that narrows blood vessels, and may thus lower blood pressure and reduce the work the heart has to perform. Since the ways in which these two kinds of drugs work are different, your doctor will decide which drug is most appropriate for you.
