Supports heightened surveillance for cerebral events after off-pump CABG with preoperative AF; leaves open whether rhythm correction improves survival.
Does preoperative atrial fibrillation worsen long-term survival and increase cerebral complications in patients undergoing off-pump coronary artery bypass surgery?
Uncorrected preoperative atrial fibrillation in patients undergoing off-pump CABG is strongly associated with reduced long-term survival and increased risk of late cerebral infarction.
