Key result
Off-pump CABG shows a non-significant trend toward lower postoperative AF vs on-pump surgery.
Why the study?
The incidence of postoperative atrial fibrillation after coronary artery bypass graft surgery with and without cardiopulmonary bypass was compared to address differences in outcomes.
Does coronary artery bypass graft surgery without cardiopulmonary bypass reduce the incidence of postoperative atrial fibrillation in patients undergoing CABG?
Comparison
Coronary artery bypass graft surgery without cardiopulmonary bypass and cardioplegia vs with cardiopulmonary bypass and standard cardioplegia

Nonsignificant trend for lower postoperative AF after off-pump CABG; hypothesis-generating, needs randomized confirmation.
Cohort (n=781)
Does coronary artery bypass graft surgery without cardiopulmonary bypass reduce the incidence of postoperative atrial fibrillation in patients undergoing CABG?
p-value: p=0.06
Off-pump CABG may be associated with a trend toward a lower incidence of postoperative atrial fibrillation compared to on-pump CABG.
Abreu et al. (1999) conducted a cohort in Coronary artery bypass graft surgery (n=781). Coronary artery bypass graft surgery without cardiopulmonary bypass vs. Coronary artery bypass graft surgery using cardiopulmonary bypass and standard cardioplegia was evaluated on Incidence of postoperative atrial fibrillation (p=0.06). Coronary artery bypass graft surgery without cardiopulmonary bypass showed a trend toward a lower incidence of postoperative atrial fibrillation compared to standard surgery (p=0.06).
