Abstract

Introduction: Identifying risk factors for atrial fibrillation in patients undergoing coronary artery bypass graft surgery can play an important role in controlling postoperative complications. Considering the challenges in determining high-risk patients in terms of atrial fibrillation dysrhythmia, the present study was performed to determine the incidence of atrial fibrillation after coronary artery bypass graft surgery and its risk factors in patients referred to hospitals affiliated to Tabriz University of Medical Sciences.

Material and Methods: This retrospective descriptive study was performed by reviewing the clinical records of 150 patients after coronary artery bypass graft surgery at Shahid Madani Hospital (Tabriz University of Medical Sciences); The status of atrial fibrillation after surgery and the factors affecting it were recorded and evaluated for all patients and the results were reported.

Results: In the present study, the incidence of atrial fibrillation in patients after coronary artery bypass graft surgery was reported to be 18.9%. In contrast, there was a significant relationship (P <0.001) between the incidence of atrial fibrillation after coronary artery bypass graft surgery and the size of the left atrium and its hypertrophy (Pearson chi-square value = 19.103).

Conclusion: Atrial fibrillation is one of the most common complications after coronary artery bypass graft surgery, which increases the length of hospital stay in the ICU and may lead to hemodynamic disturbances and increase the risk of embolism. In the present study, the incidence of atrial fibrillation after coronary artery bypass graft surgery was 18.9%.
