The aim was to study the risk factors of postoperative atrial fibrillation (POAF) following coronary artery bypass grafting (CABG) on-pump in patients without valve pathology and history of atrial fibrillation. 160 patients with indications for CABG were enrolled into a prospective comparative study. Odds ratio with 95 % CI was calculated to predict POAF from various variables. POAF lasting > 30 seconds occurred in 32 (20 %) patients. The identification of such risk factors as age > 60 years, history of Q-positive myocardial infarction, II B stage of chronic heart failure, left ventricle ejection fraction less than 40 %, dilation of left chambers of heart, NT proBNP level > 80 pg/ml, multi-vessel coronary disease, inotropic support, off-pump surgery time > 80 min was found helpful to alert the clinician about higher probability of new-onset atrial fibrillation after CABG and to guide prophylactic therapy.
