Abstract Background: Postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery, particularly coronary artery bypass grafting (CABG). Despite advances in surgical techniques, POAF remains a significant cause of morbidity and mortality. Objectives: This study investigates the potential of the Triglyceride-Cholesterol-Body weight Index (TCBI) as a predictor of POAF, focusing on the impact of nutritional status on surgical outcomes. Methods: This retrospective study included 321 patients who underwent CABG surgery between January 2010 and January 2024. TCBI was calculated […]
