摘要
目的总结并分析冠状动脉旁路移植术（CABG）患者的特点和术后早期死亡的相关危险因素。方法收集2005年1月至2007年12月接受CABG的全部310例患者的资料，并选择22个备选的死亡危险因素进行统计分析，其中术前指标15项，术中、术后指标7项。结果单因素分析显示12项危险凶素与CABG术后早期死亡相关，包括年龄、糖尿病、神经系统功能障碍、陈旧性心肌梗死、急性心肌梗死、射血分数、左主干病变、三支严重病变、急诊手术、转流时间、心肌阻断时间及术后机械通气时间。逐步Logistic回归分析显示CABG术后早期死亡的独立危险因素为：急诊手术、射血分数、年龄、转流时间和机械通气时间。结论急诊手术、射血分数、年龄、转流时间和机械通气时间是本组CABG患者术后早期死亡的独立危险因素。
Objective To analyze early mortality risk factors and clinical characteristics in our patients undergoing coronary artery bypass graft （CABG） surgery. Methods Clinical data of 310 consecutive patients undergoing CABG from January 2005 to March 2007 were collected. Twenty-two risk factors were evaluated by univariate and multivariate Logistic stepwise regression analysis. Results Univariate statistical analysis revealed that factors significantly correlated with early death were 12 variables including age, diabetes, neurological dysfunction, old myocardial infarction, acute myocardial infarction, ejection function, left main artery stenosis, emergency procedure, cardiopulmonary bypass time, aortic cross-claming time, and mechanical ventilation time. Logistic stepwise regression analysis showed that emergency procedure, ejection function, age, cardiopulmonary bypass time, and mechanical ventilation time were independent risk factor of early mortality after procedure. Conclusion Emergency procedure, ejection function, age, cardiopulmonary bypass time, and mechanical ventilation time are independent risk factors of early mortality after CABG procedure.
