Abstract

Abstract: 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, CHA2 DS2 ‐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.
