Objectives: Atrial fibrillation after coronary bypass surgery has been observed very often. In recent studies, the relationship between atrial fibrillation and epicardial adipose tissue (EAT) has been demonstrated. In our study, we aimed to investigate the relation between epicardial adipose tissue and atrial fibrillation frequency occurring after coronary artery bypass surgery.Methods: 80 patients who had undergone isolated coronary artery bypass surgery were included in the study. Preoperative transthoracic echocardiography was performed and epicardial adipose tissue thickness was measured. The incidence of postoperative atrial fibrillation were examined in patients. Results: The epicardial adipose tissue thickness of the group with postoperative AF was significantly greater (8,9 ±1,5 mm) (p Conclusion: According to our study, EAT thickness is a risk factor for the development of AF after coronary artery bypass surgery and it has been demonstrated that it increases the length of hospital stay.
