摘　　要：目的:分析单中心冠状动脉旁路移植手术(CABG)患者的特点和院内死亡相关的危险因素。方法:回顾性分析中山大学孙逸仙纪念医院209例患者资料。收集影响手术死亡的46个潜在危险因素,经过单因素与多因素Logistic回归分析确立独立危险因素。结果:全组病死率为9.09%。多因素Logistic回归分析显示:慢性肾功能不全、陈旧性心肌梗死、急诊手术、体重指数<20 kg/m^2、左心室射血分数<50%是CABG术后院内死亡的独立危险因素;乳内动脉应用是CABG术后院内死亡的独立保护性因素。结论:慢性肾功能不全、陈旧性心肌梗死、急诊手术、体重指数<20 kg/m^2、左心室射血分数<50%是CABG术后患者院内死亡的独立危险性因素;乳内动脉应用是CABG术后患者院内死亡的独立保护性因素。Objective To analyze the risk factors associated with in - hospital mortality in patients undergoing coronary artery bypass graft （ CABG） surgery. Method Consecutive 209 cases of CABG or combined CABG performed in Sun Yat - sen Memori-al Hospital were included in this study. Forty - six preoperative potential risk factors were collected and analyzed by univariate and multivariate logistic regression model to establish an independent risk factor. Results Coronary operative mortality was 9. 09%. History of chronic renal failure,prior myocardial infarction,emergent surgery,BMI 〈 20 kg/m2,left ventricular ejection fraction （ LVEF） 〈 50% were independently risk factors ; Meanwhile, utilization of internal mammary artery was an independent-ly protective factor for in - hospital mortality of CABG patients. Conclusion History of chronic renal failure, prior myocardial in-farction ,emergent suegery,BMI 〈 20 kg/m2,left ventricular ejection fraction （LVEF） 〈 50% are independently risk factors and usage of internal mammary artery is independently protective factors for in - hospital mortality of CABG paitent.
