| Abstract | ||
| Background: Atrial fibrillation (AF) is a rapid and irregular heart rhythm originating in the atria, characterized by electrical activity that disrupts effective atrial contraction. It is a common complication after cardiac surgery, particularly coronary artery bypass grafting (CABG), and, despite being mostly benign, it can increase morbidity and mortality. This retrospective cohort study (October 2022 - October 2023) aimed to identify risk factors for atrial fibrillation in 205 randomly selected CABG patients from Suez Canal University Hospitals and Ismailia Medical Complex, to improve surgical outcomes by reducing complications and mortality. Results: Postoperative atrial fibrillation (POAF) occurred in 21.9% of patients (Group 1 (POAF): 45 patients, Group 2 (non-POAF): 160 patients). Conclusions: AF is the most common arrhythmic complication after cardiac surgery. While typically benign, it increases morbidity, mortality, ICU stay duration, and hospital costs. The occurrence of POAF is associated with various risk factors; in our study, age, diabetes mellitus, large left atrial diameter, low ejection fraction, and right coronary artery (RCA) dominance were significant predictors of AF development after surgery. | ||
