PERIOPERATIVE CHARACTERISTICS IN DIABETIC VS. NON DIABETIC PATIENTS UNDERGOING CORONARY ARTERY BYPASS SURGERY

Abstract

Objectives: This study aims to compare the perioperative clinical, angiographic and operative characteristics and early complications of diabetic patients with non-diabetic patients, undergoing isolated CABG at the University Hospital for Cardiac Surgery in Skopje. Methods: During the period from October 2017 to October 2018, ninety one consecutive patients undergoing CABG were enrolled in this prospective observational study. This population was then divided into those with DM and those without DM. For these groups, preoperative clinical, angiographic, intraoperative characteristics and postoperative complications were evaluated. Results: In our cohort, 48, 4% of the patients were diabetic. Except for smoking, all other risk factor were evenly distributed between the two groups. Patients with DM had similar SYNTAX score like non-diabetic patients (31, 7±5, 5 vs. 30, 3±7, 2, p=0,312). Patients with DM had higher No of diseased vessels (2, 9±0, 7 vs. 2, 5±0, 6, p=0,020), less LM disease (22, 7% vs. 42, 6% p=0,036). There was no statistical difference between the two groups in terms of intubation time (p=0,137), inotropic support (p=0,774) and vasopressor support (p=0,076). Diabetic patients had less re-sternotomies (p=0,066) than non-diabetic patients. Postoperative AF, perioperative MI, stroke, sternal wound infection and leg wound infection were similar in both groups. Length of hospital stay was 9 days in both groups. Conclusion: Our data do not support the conclusions by other authors who found diabetes to be a risk factor for significantly adverse early morbidity following CABG. In our study DM was not risk factor for perioperative complications and preoperative characteristic of diabetic patients were not different than in no diabetic
