Aim: Diabetes mellitus is an important risk factor for coronary artery disease. In this study, we investigated the effect of diabetes on in-hospital morbidity, mortality and survival in patients undergoing isolated on-pump CABG operation. we also investigated the effect of pre- and perioperative factors on in-hospital morbidity, mortality and survival.
Methods: Between January 2002 and December 2009, 1657 patients underwent isolated CABG in our clinic. Among these patients, 35.7% (n: 591) were diabetic, whereas 64.3% (n: 1066) were non-diabetic.
Results: Five independent predictive factors of in-hospital mortality rate in a multivariate regression analysis in patients with diabetes were identified, including prolonged cardiopulmonary bypass time (>3 h), prolonged operation time, prolonged ventilatory support, postoperative atrial fibrillation and postoperative renal insufficiency. In-hospital mortality rate was 8.1% (48) and 1.4% (15) in patients with and without diabetes, respectively (P=0.000). Length of intensive care unit and hospital stay were longer in patients with diabetes (P=0.000). Mean follow-up was 49.08±25.39 months and 47.79±25.06 months in patients with and without diabetes. Mid-term survival rate was 94.7% and 95% in patients with and without diabetes.
Conclusion: In-hospital mortality rate and morbidity rate were higher in patients with diabetes undergoing isolated on-pump CABG. Mid-term survival was similar in patients with and without diabetes.
