Özet

ABSTRACT Aim: There are many etiological factors that affect the occurrence of atrial fibrillation (AF) after coronary artery bypass grafting (CABG) surgery. Determining these factors will make significant contributions to the prevention of postoperative atrial fibrillation and therefore to the reduction of mortality and morbidity. In this study, the relationship between cardiopulmonary bypass (CPB) and cross-clamp times and the development of postoperative AF was examined. Methods: All patients who underwent isolated CABG surgery by the same surgical team in our clinic between September 2018 and December 2019, had normal thyroid function tests, used βblockers, and did not have heart valve disease were prospectively included in the study and their perioperative data were recorded. Results: 103 patients who met the specified criteria were included in the study. The mean age was 62.51±10.01 (range 47-84) and 82 (79.6%) were male. The patients were divided into two groups as those who developed AF and those who did not. AF developed in 25 of 103 patients (24.3%). All patients underwent isolated CABG under standard CPB. The mean duration of CPB was found to be 81.2 ± 27.47 minutes in those with AF and 83.33 ± 17.35 minutes in those who did not, and there was no statistical difference (p=0.717). The mean cross-clamp time was 39.04 ± 12.12 minutes in those with AF and 40.14 ± 8.89 minutes in those who did not. Statistically, the relationship between cross-clamp time and AF was not significant (p=0.625). Conclusion: As a result of our study, it was observed that there was no significant relationship between CPB and cross-clamp times and the incidence of postoperative atrial fibrillation. However, we believe that there is a need for large-scale and multicenter clinical studies on the subject. Key words: Cardiopulmonary bypass time, coronary artery bypass grafting, cross-clamp time, postoperative atrial fibrillation.
