In the recent years there has been registered an increase in diabetes mellitus (DM) morbidity, especially among able-bodied citizens. The steady increase in amount of DM patients inevitably leads to the increase in the amount of diabetic CHD patients – candidates for the surgical myocardial revascularization. This article contains analysis of choice of myocardial revascularization technique in patients with CHD and concomitant DM. It also contains data from the study of endovascular and surgical treatment of CHD results in diabetic patients. This study also included postoperative complications analysis with exposure of complication development predictors and was held in Bakulev Scientific Centre of cardiovascular surgery. Results obtained in the study testify to the fact that DB increases relative risk of cardio-vascular complications (cardiac death, myocardial infarction and restenosis of special-purposed stenosis) development in patients with CHD after percutaneous coronary intervention with stenting. DM is an independent risk factor that increases myocardial infarction development risk, recurrence of stenocardia and shunt failure during the three year follow up after the coronary artery bypass grafting done in CHD patients.
