Impact of On-pump Versus Off-pump Coronary Artery Bypass on Oxidative Stress and Postoperative Atrial Fibrillation

Objectives: Postoperative atrial fibrillation (POAF) is common after coronary artery bypass grafting (CABG).Gammaglutamyl 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.
