Angiotensin converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARB)
are medicines used to treat a heart attack, heart failure, or decreased functioning
of the left side of your heart (left ventricular systolic dysfunction (LSVD)).
Why this is important:
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
narrows blood vessels. This helps reduce the pressure in your heart and lower blood
pressure. If you have a heart attack, you should receive a prescription for ACE inhibitors
before you leave the hospital.
The chart above shows the percentage of heart attack patients that were given ACE or ARB inhibitor for LSVD.
