title: Mortality predictors in ST-elevated myocardial infarction patients undergoing coronary artery bypass grafting.
abstract: The use of coronary artery bypass grafting (CABG) in primary treatment of acute myocardial infarction is still debated. We evaluated the predictors of mortality in patients undergoing primary CABG for ST-elevated myocardial infarction (STEMI). Between January 2003 and January 2008, all patients referred to our institution with STEMI who did not qualify for primary angioplasty and required CABG were included in this study. Survivors and nonsurvivors were compared retrospectively in terms of demo-graphics, preoperative, intraoperative, and postoperative characteristics. Preoperatively confirmed cases of STEMI (n = 150) were included in the analysis. There were 114 survivors and 36 nonsurvivors. In-hospital mortality rate was 22%. In Cox regression analysis age, cardiogenic shock (Killip ≥3), preoperative cardiac troponin levels, preoperative use of intra-aortic balloon counterpulsation (IABP), previous myocardial infarction, and percutaneous coronary intervention were independent predictors of in-hospital mortality. After multivariate analysis, factors predicting in-hospital mortality were age, preoperative cardiac troponin levels, and preoperative IABP. Age, preoperative cardiac troponin levels, and preoperative IABP use were predictive factors of in-hospital mortality in patients undergoing primary CABG for STEMI.
