Key result
In elderly patients undergoing isolated elective off-pump coronary artery bypass surgery, the prevalence of postoperative atrial fibrillation was 48.3%.
Why the study?
Postoperative atrial fibrillation frequently complicates CABG, leading to thromboembolic events and prolonged hospital stays, but its prevalence following OPCAB in elderly patients needed determination.

Postoperative atrial fibrillation is highly prevalent (48.3%) in elderly patients undergoing off-pump coronary artery bypass surgery, highlighting the need for preoperative risk management.
Warrants preoperative POAF risk assessment in elderly off-pump CABG; leaves open targeted prevention trials.
Background Atrial fibrillation (AF) is one of the frequent complications following coronary artery bypass surgery. Postoperative atrial fibrillation (POAF) can lead to thromboembolic events and prolong hospital stays. We aimed to determine the prevalence of POAF following off-pump coronary artery bypass surgery (OPCAB) in the elderly population. Materials and Methods This cross-sectional study was carried out between May 2018 to April 2020. Elderly patients (age ≥65 years) admitted for isolated elective OPCAB were eligible for the study. A total of 60 elderly patients were evaluated based on the preoperative and intraoperative risk factors and postoperative outcomes during the hospital stay. Results The mean age was 67.83±4.06 years, and the prevalence of POAF in elderly adults was 48.3%. The mean number of grafts was 3.20±0.73, and ICU stays at 3.43±1.61 days. The mean duration of the hospital stays was 10.03±2.12 days. Although stroke developed in 1.7% of post-CABG patients, no mortality was observed postoperatively. Conclusion POAF is one of the commonly encountered complications following OPCAB. Though OPCAB is a superior revascularization procedure, preoperative planning and attention are especially needed in the elderly to reduce the prevalence of POAF.

Kumar et al. (2023) conducted a cross-sectional in Coronary artery disease requiring off-pump coronary artery bypass surgery (n=60). Off-pump coronary artery bypass surgery (OPCAB) was evaluated on Prevalence of postoperative atrial fibrillation (POAF). In elderly patients undergoing isolated elective off-pump coronary artery bypass surgery, the prevalence of postoperative atrial fibrillation was 48.3%.
