The medical re-cords of 816 type 2 diabetic patients who un-derwent primary, isolated CABG surgery during 1997-2003 were studied. The Kaplan-Meier me- thod and Cox regression were used to estimate survival and the independence of prognostic factors associated with all-cause mortality. One hundred and five out of 816 patients expired during the 7-year period. The overall survival rate was 83.5% (95%CI: 78.7-88.3%). Associated prog- nostic factors varied by gender. For males, but not for females, smoking (RR=3.44, 95%CI: 1.01- 11.70), myocardial infarction (RR=4.77, 95% CI: 1.23-18.86), respiratory failure (RR=4.21, 95% CI: 1.48-7.99), cardiogenic shock (RR=12.58, 95% CI: 3.25-20.77), and congestive heart failure (RR= 3.77, 95%CI: 1.10-13.45) were significantly related to all-cause mortality. Older age at sur-gery (RR= 1.15, 95%CI: 1.04-1.27), emergent op-eration (RR= 21.29, 95%CI: 10.03-39.43), pul-monary ede-ma (RR=7.72, 95%CI: 1.89-15.59), and days of ICU stay (RR=1.05, 95%CI: 1.02-1.09) were significant- ly related to all-cause mortality in females only. In conclusion, several gen-der-related differences were noted pertaining to all-cause mortality and its relationship to smok- ing, myocardial infarction, respiratory failure, cardiogenic shock, congestive heart failure, older age at surgery, emergent operation, pul-monary edema, and days of ICU stay.展开更多
