Early results of coronary artery bypass grafting in patients with ischemicheart disease and type II diabetes

We compared early results of coronary artery bypass grafting (CABG) in 85 p atients with coronary artery disease (CAD) and type 2 diabetes mellitus (DM ) and 175 non-diabetic patients with CAD operated in Myasnikovs Institute o f Clinical Cardiology between January 1995 and December 1998 by one surgica l team. Patients of both groups were comparable concerning age gender, freq uency of previous myocardial infarctions (MI), and congestive heart failure . Patients with DM were obese and hypertensive. Diabetic patients had more lesions of left main coronary artery, 3-vessel lesions, total occlusions, l esions in secondary coronary arteries, and ejection fraction < 50%. The use of a. mammaria for coronary shunting was the same in both groups but opera tion of endarterectomy and autovenous grafting were more frequent in diabet ic patients. The operative mortality was 1,2% in diabetic patients and 1,1% in non-diabetic (p>0,05). Perioperative complications were the following: myocardial infarction 1,2% and 1,1%, stroke 4,7% and 2,8%, arterial flutter 16,4% and 13,1%, mediastinitis 2,4% and 1,7%, and bleeding 5,9% and 5,1%, respectively tin all cases p>0,05). Thus, although patients with type 2 DM had clinically and angiographically more severe CAD, the early outcomes of CABG were the same as in non-diabetic patients.
