The OPCAB (off-pump CABG) technique was associated with a significantly lower frequency of postoperative atrial fibrillation compared to standard CABG (OR 0.75).

What are the independent risk factors for developing atrial fibrillation following coronary artery bypass grafting?
Advanced age, prior arrhythmias, heart failure, standard CABG technique, and repeated revascularization increase the risk of postoperative AF, whereas beta-blockers and off-pump CABG are protective.
Odds Ratio: 0.75 (95% CI 0.72–0.87)
Absolute Event Rate: 19.3% vs 23.7%
p-value: p=0.02
BACKGROUND: To evaluate the risks factors of atrial fibrillation (AF) following coronary artery bypass grafting (CABG). METHODS AND RESULTS: Twelve hundred patients subjected to CABG were included. Postoperative AF developed in 278 patients (23.2%). Statistical analysis identified 5 independent predictors of AF: advanced age, history of supraventricular arrhythmias, preoperative heart failure, operation with standard CABG technique and repeated revascularization. CONCLUSIONS: Postoperative AF caused a significant increase in mortality and hospitalization length. There were 4 independent risk factors of postoperative AF. Administration of beta-blockers and the OPCAB (off-pump CABG) operating technique were identified as protective factors.
Banach et al. (2006) conducted a cohort in Isolated coronary artery disease (n=1,200). OPCAB (off-pump CABG) technique vs. Standard CABG technique was evaluated on Postoperative atrial fibrillation (OR 0.75, 95% CI 0.72-0.87, p=0.02). The OPCAB (off-pump CABG) technique was associated with a significantly lower frequency of postoperative atrial fibrillation compared to standard CABG (OR 0.75).
