Abstract:
Objective To identify the risk factors for hospital mortality in patients with acute myocardial infarction (AMI) after emergency coronary artery bypass grafting (CABG). Methods We retrospectively analyzed the clinical data of 145 AMI patients undergoing emergency CABG surgery in Qingdao Municipal Hospital from 2009 to 2019. There were 108 (74.5%) males and 37 (25.5%) females with a mean age of 67.7±11.5 years. According to whether there was in-hospital death after surgery, the patients were divided into a survival group (132 patients) and a death group (13 patients). Preoperative and operative data were analyzed by univariate analysis, followed by multivariate logistic regression analysis, to identify the risk factors for hospital mortality. Results Over all, 13 patients died in the hospital after operation, with a mortality rate of 9.0%. In univariate analysis, significant risk factors for hospital mortality were age≥70 years, recent myocardial infarction, left ventricular ejection fraction (LVEF)<30%, left main stenosis/dissection, operation time and simultaneous surgeries (P<0.05). Multivariate logistic regression analysis showed that LVEF<30%(OR=2.235, 95%CI 1.024-9.411, P=0.014), recent myocardial infarction (OR=4.027, 95%CI 1.934-14.268, P=0.032), operation time (OR=1.039, 95%CI 1.014-1.064, P=0.002) were independent risk factors for hospital mortality after emergency CABG. Conclusion Emergency CABG in patients with AMI has good benefits, but patients with LVEF<30%and recent myocardial infarction have high in-hospital mortality, so the operation time should be shortened as much as possible.
