The perioperative period data were collected, and logistic regression was used to analyze the independent predictors of the occurrence of POAF after CABG and the related predictive values of risk factors were analyzed by using the subjects’ work characteristic curve (ROC).Results: A total of 169 patients were included, and there are 45 patients in the POAF group, with an incidence of 26.6%, and 124 in the non-POAF group. The POAF group was significantly higher than the non-POAF group in terms of age (69.2± 8.8 years vs 62.3± 9.3 years) and preoperative LAD (42.7± 7.2mm vs 36.8± 5.5mm), and the difference was significant (P 64.5 years, LAD > 41mm, and HDL-C < 0.9 mmol/l were the cut-off values for predicting the occurrence of POAF (AUC1=0.733; AUC2=0.741; AUC3=0.647, P < 0.05). The combined age + LAD + HDL-C (AUC = 0.755; P < 0.05) had a higher diagnostic value and high sensitivity.Conclusion: The age, LAD, and HDL-C are independent risk factors for the POAF after CABG, and clinicians should assess these risk factors as much as possible when managing patients in the perioperative period and make corresponding measures to prevent the development of POAF.Keywords: coronary artery bypass grafting, left atrial diameter, left ventricular ejection fraction, high density lipoprotein cholesterol, atrial fibrillation
