Early outcomes of isolated coronary artery bypass grafting in Chinese aged patients with diabetes mellitus.
OBJECTIVE
To compare the early outcomes of coronary artery bypass grafting (CABG) in aged diabetic patients, and evaluate the affection of diabetes on the early outcomes of CABG in aged patients.


METHODS
The study took place in the Department of Cardiovascular Surgery, Shanghai Jiao Tong University Affiliated First People's Hospital, Shanghai, China, between January 2000 and July 2008. Five hundred and ninety-three elderly patients (age > or = 70-years-old), undergoing isolated CABG were retrospectively divided into diabetic group and non-diabetic group. We analyzed the pre-operative, intra-operative, and post-operative variables of the 2 groups. The t-test, Chi-square test, and multivariate logistic regression were used to determine the differences between the 2 groups of patients.


RESULTS
There was no statistical difference of pre-operative and intraoperative variables between the 2 groups, except that there were more left main coronary artery diseases in the diabetic group. Values in the post-operative period such as morbidity, complications, and blood infusion had no differences between the 2 groups. Diabetes mellitus and age are not the risk factors for in-hospital mortality.


CONCLUSIONS
Coronary artery bypass grafting in elderly patients is plausible. Furthermore, diabetic patients could get the same surgical results as those non-diabetic patients.
