ACE inhibitors are of particular benefit in patients with large anterior infarctions, especially those with compromised left ventricular function (eg, from ST-elevation MI [STEMI]) but without hypotension. The benefit in patients with unstable angina is less clear.

Currently, ACE inhibitors are recommended in patients with left ventricular dysfunction or congestive heart failure, diabetes, and hypertension. ACE inhibitor therapy may be started within 24 hours of admission and titrated for blood pressure effect.
