Abstract

Objectives. To study the effect of diabetes mellitus (DM) on the results of coronary artery bypass grafting (CABG) surgery in patients with coronary artery disease.Material and Methods. The results of CABG surgery were studied in 800 patients with coronary artery disease. The patients were divided into 2 groups: Group 1 included 307 patients (38.4%) with diabetes, group 2 consisted of 493 non-diabetic patients (61.6%). In these 2 groups, the types of coronary artery disease and their complications, the presence of comorbidities, the surgery duration, the revascularization index, the need for inotropes and the postoperative course were compared.Results. There were no significant differences in the incidence of recurrent myocardial infarction (11 cases (3.5%) vs 15 cases (3%)), the need for revascularization (6 cases (1.9%) vs 7 cases (1.4%)), as well as in the development of ischemic stroke (3 cases (1%) vs 3 cases (0.7%)) in the early postoperative period between the groups with diabetes and without diabetes. 3 patients (0.9%) of diabetes group developed acute renal failure (ARF) versus no observed cases in non-diabetes group. Also the incidence of infectious and inflammatory complications was higher in diabetes group (8     27Shoshilinch tibbiyot axborotnomasi, 2020, 13-tom, 6-soncases (2.6%) vs 2 cases (0.4%) in diabetes and non-diabetes groups respectively). Patients with diabetes stayed in the hospital 4 days more than non-diabetic patients on average.Conclusion. In the group of patients with DM non-fatal recurrent myocardial infarction (3.5%), ischemic stroke (1%), acute renal failure (0.9%) and infectious-inflammatory complications were developed and the duration of hospital stay in such patients was longer. However, no significant differences were found in the development of severe postoperative complications and mortality between compared groups.
