Abstract 383: Effect of Race on Risk of Recurrent Myocardial Infarction After Index Myocardial Infarction

Abstract

Background: Though the prevalence of coronary artery disease is known to be highest in African Americans, it is unclear if there are any racial factors predisposing patients for a recurrent Myocardial Infarction (MI) after index MI. Methods: We reviewed 6,626 cases of MI at a single quaternary care medical center from January 1 st , 2010 to January 1 st , 2017 (29% STEMI, 71% NSTEMI), and we identified all cases of recurrent MI within 90 days of discharge after index MI. The patients were categorized according to their corresponding races into White Americans, African Americans, and Others. Result: Out of the 6626 initial cases of MI, 72% were white patients, 25% were African Americans and 3% belonged to other races. A total of 2051 patients were readmitted within 90 days of index admission, of which 168 patients were readmitted with an MI. Only 2.1% of White patients developed a recurrent MI whereas 4% of African Americans were readmitted with a recurrent MI (P=0.003). Conclusion: We observed that African Americans were more likely to be readmitted with a recurrent MI than White Americans. Understanding the reasons for this increased risk in MI can translate into improved care for African Americans.
