Coronary artery bypass surgery use of beta-blockers



==ACCF/AHA Guidelines for Perioperative use of Beta-Blockers == {{cquote|

Class I
1. 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. (Level of Evidence: B)

2. 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. (Level of Evidence: B)

3. Beta blockers should be prescribed to all CABG patients without contraindications at the time of hospital discharge. (Level of Evidence: C)

Class IIa
1. Preoperative use of beta blockers in patients without contraindications, particularly in those with an LVEF greater than 30%, can be effective in reducing the risk of in-hospital mortality. (Level of Evidence: B)

2. Beta blockers can be effective in reducing the incidence of perioperative myocardial ischemia. (Level of Evidence: B)

3. Intravenous administration of beta blockers in clinically stable patients unable to take oral medications is reasonable in the early postoperative period. (Level of Evidence: B)

Class IIb
1. The effectiveness of preoperative beta blockers in reducing inhospital mortality rate in patients with LVEF less than 30% is uncertain. (Level of Evidence: B)}}
