Preoperative AF was associated with higher postoperative risks; hypothesis-generating for targeted preoperative management trials in cardiac surgery.
Does preoperative atrial fibrillation increase the risk of postoperative complications and in-hospital mortality in patients undergoing cardiac surgery?
Preoperative atrial fibrillation is an independent risk factor for increased in-hospital mortality and major complications following cardiac surgery.
