Predictors and Impact of In-Hospital Recurrent Myocardial Infarction in Patients with Acute Coronary Syndrome: Findings from Gulf RACE-2

Abstract

Background: Little is known about the predictors and prognostic impact of recurrent in-hospital ischemia and infarction in patients with acute coronary syndrome (ACS). Our objectives were to determine the baseline characteristics, risk factors, and long-term outcomes of patients with recurrent myocardial infarction (Re-MI). Methods: We evaluated patients with ACS who were enrolled in the second Gulf Registry of Acute Coronary Events from October 2008 to June 2009. Results: Of 7925 patients with ACS, 167 (2.1%) developed in-hospital Re-MI. Patients with Re-MI were older (mean age: 58.7 ± 13.4 vs 56.8 ± 12.6; P =.045), had higher rates of hyperlipidemia (42.5% vs 32.6%; P =.019), and were more likely to present with ST-segment elevation myocardial infarction (STEMI; 74.25% vs 43.9%; P
