Key result
Advanced age linked to ~31% higher odds of POAF following OPCAB.
Why the study?
Postoperative atrial fibrillation frequently complicates CABG, leading to adverse outcomes, but differences in its prevalence and risk factors following OPCAB between elderly and young patients needed comparison.
Does elderly age increase the risk of postoperative atrial fibrillation following off-pump coronary artery bypass graft surgery compared to young age?
Population
120 patients undergoing OPCAB (60 elderly and 60 young)
Comparison
Elderly patients (aged ≥65 years) vs young patients (aged <65 years)
Design
Prospective comparative study
Follow-up
During the hospital stay

Does elderly age increase the risk of postoperative atrial fibrillation following off-pump coronary artery bypass graft surgery compared to young age?
Odds Ratio: 1.31 (95% CI 1.14–1.52)
Absolute Event Rate: 48.3% vs 20%
p-value: p=<0.0001
Elderly patients undergoing off-pump CABG have a significantly higher risk of developing postoperative atrial fibrillation compared to younger patients, which is associated with longer ICU and hospital stays.
Kumar et al. (2023) conducted a cohort in Coronary artery disease requiring off-pump coronary artery bypass graft surgery (n=120). Advanced age (≥65 years) vs. Young age (<65 years) was evaluated on Postoperative atrial fibrillation (POAF) (OR 1.31, 95% CI 1.14-1.52, p=<0.0001). Advanced age (≥65 years) was an independent predictor of postoperative atrial fibrillation following off-pump coronary artery bypass graft surgery, with a prevalence of 48.3% in elderly patients compared to 20% in young patients.
