What is the recommendation for the use of beta blockers to reduce the incidence or clinical sequelae of postoperative AF in CABG patients?
Class I: Beta blockers should be administered for at least 24 hours before CABG to all patients without contraindications to reduce the incidence or clinical sequelae of postoperative AF. Additionally, beta blockers should be reinstituted as soon as possible after CABG in all patients without contraindications to reduce the incidence or clinical sequelae of AF.
