Receiving a beta-blocker (HR, 0.60; 95% CI, 0.41–0.87) or an ACE inhibitor (HR, 0.65; 95% CI, 0.44–0.95) upon discharge for anterior MI were significant protective factors, but warfarin use for up to 90 days post-MI was not (HR, 0.68; 95% CI, 0.37–1.26). Here, ACE is linked to myocardial infarction.
