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

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).
