Angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) are medicines used to treat heart attacks, heart failure, or a decreased function of the heart.
Why it is important:
ACE inhibitors are frequently prescribed for a condition called "left ventricular systolic dysfunction" (LVSD), which is a decreased function of the left part of your heart. ACE inhibitors can help reduce the risk of death from a heart attack if taken within 24 hours of the first symptoms of a heart attack. Continued use may help prevent heart failure. ACE inhibitors work by stopping the production of a hormone that can narrow your blood vessels. This helps reduce the pressure in your heart, lowering your blood pressure.
The chart above shows the percentage of patients that were given ACE inhibitors for left ventricular systolic dysfunction (LVSD).
