Objectives: Postoperative atrial fibrillation (PoAF), an important clinical condition that can occur after coronary artery bypass graft (CABG) operations, may bring about cerebrovascular risks, prolong hospital stay and increase treatment costs. In this prospective study, we aimed to investigate the predictive value of HATCH score and waist/height ratio (WHR) values in revealing the development of PoAF after CABG operations. Methods: Patients who underwent isolated CABG surgery with cardiopulmonary bypass between May 2019 and November 2019 were prospectively included in the study. Preoperative demographic characteristics, laboratory parameters, and operative parameters of the patients were recorded prospectively. Results: A total of 255 patients were included in the study. Those who did not develop PoAF were included in Group 1 (N ¼ 196, mean age ¼ 58.9 ± 9.4 years), and those who did were included in Group 2 (n ¼ 59, mean age ¼ 61.1 ± 12 years). There were no statistically significant differences between the two groups in terms of age, gender, presence of hypertension and hyperlipidemia. Rates of chronic obstructive pulmonary disease and previous percutaneous coronary interventions, waist circumference, waist to height ratio and HATCH score values were significantly higher in Group 2 compared to Group 1 ( p values: 0.019, 0.034, 0.001, < 0.001, < 0.001, respectively). In multivariate analysis, WHR (Odds ratio: 1.068, Confidence interval: 1.032e1.105, p < 0.001) and HATCH score (Odds ratio: 2.590, Confidence interval: 1.850e3.625, p < 0.001) were independent predictors of PoAF. Conclusions: With this current prospective study, we showed that calculating WHR and HATCH score in the preoperative period can help us predict PoAF.
