Abstract
Objective of the study: to identify preoperative and intraoperative risk factors associated with complicated postoperative outcomes in patients who underwent coronary artery bypass grafting.
Materials and methods. A single-center retrospective analysis was conducted on 249 random cases of coronary artery bypass grafting from a total registry of 1,392 patients for the years 2019–2025. Propensity score matching was used to create comparable groups, resulting in balanced comparable paired groups.
Research results and discussion. The frequency of early postoperative complications after coronary artery bypass grafting is 12,2 %. The most significant predictors of complication development are permanent atrial fibrillation (OR 3,75; 95 % CI 1,65–8,50; p < 0,01) and hyperlactatemia (OR 1,68; 95 % CI 1,02–2,75; p = 0,04).
Conclusion. The identified risk factors can be used to predict complicated courses and optimize perioperative management of patients undergoing CABG.
