| Abstract | ||
| Background: After coronary artery bypass grafting (CABG), postoperative atrial fibrillation (POAF) is a frequent and dangerous side effect that is linked to higher risk of thromboembolic events, longer hospital stays and increased morbidity. Nevertheless, little is known about the long-term consequences and risk factors for POAF development following solitary CABG. So, we aimed to assess the long-term outcomes of patients who developed new-onset atrial fibrillation after undergoing isolated coronary artery bypass grafting and identify independent predictors of POAF occurrence. Methods: This retrospective cohort study was carried out at the National Heart Institute, General Organization for Teaching Hospitals and Institutes (GOTHI) on 100 adult patients who had isolated CABG. Patients were divided into: those with POAF and those without. Long-term outcomes such Major Adverse Cardiac and Cerebrovascular Events (MACCE) were evaluated. Results: Of the patients, 36% experienced POAF. Age, hypertension, heart failure, peripheral vascular disease, and prior ischemic stroke were all significantly greater in the POAF group. POAF patients had significantly higher serum creatinine levels, spent more time in the intensive care unit and in the hospital. POAF was linked to a significantly higher incidence of ischemic stroke, heart failure, and recurrent atrial fibrillation during follow-up. Conclusion: Postoperative atrial fibrillation after isolated CABG is a common complication occurring in more than one-third of patients and is associated with significant long-term morbidity including increased risks of stroke, heart failure, and arrhythmia recurrence. Advanced age, cardiovascular comorbidities, and renal dysfunction are key predictors of POAF development. | ||
