Abstract：Objective To analyze related factors of death in patients with coronary artery bypass grafting (CABG).Methods Totally 12 200 cases of CABG were performed in Beijing Anzhen Hospital,Capital Medical University from January 2008 to January 2013,182 cases died.Clinical data of the death cases were retrospectively analyzed,including age,heart function,coexisting lesions and cause of death.Results The death rate in patients over 70 years old was 1.8％ (78/4 353),which was significantly higher than that in patients under 70 years old [1.3％ (104/7 847)] (P ＜ 0.01).Different coexisting lesions with death rates from high to low were acute myocardial infarction[12.1％ (34/281)],left ventricular dysfunction [6.3％ (78/1 238)],left main coronary lesion[4.5％ (40/887)],ischemic mitral regurgitation [3.6％ (19/528)] and ventricular aneurysm [2.0％ (5/250)].The death rate in patients with left ventricular ejection fraction (LVEF) ＜ 50％ was 6.3％ (78/1 238),which was significantly higher than that in patients with LVEF≥50％ [0.9％ (104/10 962)] (P ＜ 0.01).The common causes of death were heart failure [72.0％ (131/182)] and multiple organ failure [21.4％ (39/182)].Conclusions Death risk of CABG is associated with advanced age,acute myocardial infarction,left ventricular dysfunction,left main coronary disease and ischemic mitral regurgitation.The common causes of death are heart failure and multiple organ failure.
