This observational study aims to identify the determinants or predictors of postoperative atrial fibrillation (POAF) in patients who have undergone coronary artery bypass grafting (CABG). The study will compare two cohorts: patients who developed POAF and those who did not (non-POAF), with the aim of improving postoperative care, reducing complications, and refining patient risk stratification.
Demographics (age, sex, ethnicity), lifestyle factors (smoking, alcohol, physical activity), and medical history (diabetes, hypertension, prior heart diseases) will be recorded. Surgical procedure details (number of grafts, use of intraoperative devices), anesthesia, and medications administered. Levels of inflammatory markers, cardiac-specific markers, and other relevant biomarkers at baseline and postoperatively. Other complications besides POAF, hospital length of stay, ICU admission, readmission rate, and mortality will also be monitored.

All participants in the study will undergo the standard procedure of CABG. Continuous electrocardiogram monitoring and electrocardiography were used to identify the cardiac rhythm.
