Abstract：Objective To investigate the short-and mid-term efficacies of off-pump coronary artery bypass grafting (OPCABG) in male patients over 70 years old.Methods Perioperative data of 100 male patients 70 years or older who had OPCABG from January 2008 to February 2009 in Beijing Anzhen Hospital,Capital Medical University were retrospectively analyzed.Risk factors of postoperative oxygen index (OI) were identified by multivariate linear regression.Survival analysis was performed by Kaplan-Meier method during 100 months after operation.Results The mean age of 100 patients was (73.1 ± 2.5) years;the in-hospital mortality was 2.0％ (2/100).Smoking history,intraoperative plasma transfusion volume,left ventricular ejection fraction less than 40％,ventricular aneurysm history and myocardial infarction history were independent factors of postoperative OI (P ＜0.05).The lost of follow-up rate was 15.3％ (15/98);1-year survival rate was 95.3％ (81/85);2-years survival rate was 94.1％ (80/85);3-years survival rate was 91.8 ％ (78/85);7-years survival rate was 83.5％ (71/85);the survival rate and angina-free survival rate at 100 months after operation was 81.2％ (69/85) and 78.8％ (67/85).Conclusion Outcomes of OPCABG in male patients over 70 years old are encouraging;the in-hospital mortality and 100 months survival rate are acceptable.
