INFLUENCE OF DIABETES MELLITUS ON OPERATIVE OUTCOME OF CORONARY ARTERY BYPASS GRAFT SURGERY

BACKGROUND Diabetes Mellitus (DM) was present in around 47% of population in India undergoing coronary artery bypass surgery for coronary artery disease. Our aim of the study was to determine possible pre-operative and post-operative risk factors and mortality associated with diabetes during coronary artery bypass grafting (CABG). MATERIAL AND METHODS We analyzed retrospective data of 224 patients at our institute operated between January 2014 to March 2014. The preoperative, intra operative and postoperative risk factors as well as the complications and 30-day mortality rates were compared between the diabetics and non-diabetics. Among the 224 patients; 132 (58.93%) were in non-diabetic group and 92(41.07%) were diabetics. RESULTS The 30-day mortality was 11% in patients with DM and 3% in those without DM; we observed that BMI, hypertension and weight were highly significant in diabetic group compared to non-diabetic group. Prothrombin time, inotropes duration, ICU stay, hospital stay and mechanical ventilation hours were also significantly high in diabetic group compared to non-diabetic group. CONCLUSION DM is an important risk predictor for short term mortality and morbidity among those undergoing CABG.
