Myocardial revascularization using coronary artery bypass grafting (CABG) is the gold standard for the treatment of chronic ischemic heart disease (CHD) with multivessel coronary artery disease. A common complication of CABG is rhythm disturbance in the form of atrial fibrillation (AF). After surgery, it most often occurs on the second and third days and has a short-term period, going away on its own. New postoperative AF (POAF) can lead to thromboembolic complications, hemodynamic disturbances, and an increase in the length of the patient's hospital stay. It is very important to identify markers that are triggers for the onset of POAF. Various studies demonstrate risk factors for POAF in the form of comorbidities, associated conditions, systemic inflammatory response, and intraoperative factors. In this regard, the purpose of our study was to study and determine intraoperative markers of POAF development in patients with chronic ischemic heart disease after CABG.
