Objectives: Postoperative atrial fibrillation (POAF) is common after coronary artery bypass grafting (CABG). Gamma-glutamyl transferase (GGT), an index of oxidative injury, could provide predictive information regarding POAF. Materials and Methods: Patients who underwent on-pump or off-pump CABG between January 2019 And December 2023 were included in this retrospective cohort study. Both pre- and post-CABG GGT concentrations were documented. POAF events were continuously monitored by means of telemetry. Tables provide information on demographics, biochemical measures, and POAF outcomes. Results: A total of 183 patients were included in the analysis. POAF occurred more frequently in on-pump patients (35%) Than in off-pump patients (20%). Postoperative GGT levels were significantly higher in the POAF group. estimated p-values are included in all the tables below. Conclusion: High levels of postoperative GGT are correlated with POAF after CABG.
