Coronary artery bypass graft surgery (CABG) is followed by short-term and long-term complications such as surgical-site bleeding and infection, myocardial infarction and etc. Regarding the high proportion of patients with diabetes mellitus undergoing this surgery, understanding the impacts of this condition on CABG outcomes seems necessary. This study intends to compare postoperative complications between diabetic and non-diabetic patients after CABG surgery.


The present research is a cross-sectional retrospective study, including 680 patients who underwent CABG in Imam Khomeini Hospital, Iran during April 2006 to March 2009. Patients’ demographic data and post-operative complications were obtained and analyzed.


680 patients were enrolled in this study, 440of whom were males. 187 patients were diagnosed with diabetes. Our study indicates although there was no statistically significant difference in reoperations due to bleeding, overall infection, surgical-site infection, ATN incidence, and mortality rate between diabetic and nondiabetic patients, however cardio pulmonary bypass time (CPB) was significantly higher in diabetic patients.


Diabetes increases cardiopulmonary bypass time, but does not majorly affect other CABG complications
