Objective Atrial fibrillation (AF) after coronary artery bypass grafting (CABG) is a factor that causes an increase in mortality and morbidity. Therefore, predicting post‐CABG AF development is important for treatment management. In this study, we investigated the value of the ratio E/(Ea × Sa) as a combined systolic‐diastolic index in predicting post‐CABG AF development. Methods This prospective study included 102 patients who underwent only isolated coronary bypass. Preoperative demographic features, biochemical, and hematological parameters, and the electrocardiographic data of all patients were recorded. The E/(Ea × Sa) indices were calculated from the echocardiographic measurements. Those who retained their postoperative sinus rhythm were defined as group 1, and those who developed AF were defined as group 2. Results Group 2 had significantly higher lateral (group 1:1.14 ± 0.61 vs. group 2:1.47 ± 0.87; P = .02), medial (group 1:1.61 ± 0.70 vs. group 2:1.99 ± 0.91; P = .02), and mean (group 1:1.30 ± 0.58 vs. group 2:1.62 ± 0.74; P = .001) E/(Ea × Sa) indices than group 1. In the univariate analysis, age, CHA 2 DS 2 ‐VASc score, sPAP, IABP use, and mean E/(EaxSa) index were found to be significant predictors of post‐CABG AF development. However, only the mean E/(EaxSa) index was found to be a significant predictor of post‐CABG AF development in the multivariate analysis (OR: 2.19 95% CI 1.01–5.96; P = .045). Conclusions The combined systolic‐diastolic index predicted the development of post‐CABG AF.
