Restarting beta blockers after cardiac surgery significantly reduces the incidence and severity of post-operative atrial fibrillation (AF). This approach also speeds up rhythm conversion in patients, particularly older individuals.

Area of Science:

  • Cardiology
  • Cardiac Surgery
  • Pharmacology

Background:

  • Post-operative atrial fibrillation (AF) is a common complication following cardiac surgery.
  • Beta blockers are frequently used preoperatively but their postoperative continuation is debated.

Purpose of the Study:

  • To evaluate the efficacy of restarting beta blockers in the postoperative period after coronary artery bypass grafting (CABG).
  • To assess the impact on the incidence and severity of post-operative atrial fibrillation (AF).

Main Methods:

  • A randomized controlled trial involving 210 patients undergoing elective CABG.
  • Patients were assigned to either a control group (no postoperative beta blockers) or a beta blocker group (resumed medication).
  • Both groups were matched for baseline characteristics and surgical technique.

Main Results:

  • A significantly lower incidence of AF was observed in the beta blocker group (18/105) compared to the control group (40/105) (P < 0.02).
  • Patients receiving postoperative beta blockers showed a higher rate of conversion to sinus rhythm within 24 hours (76% vs. 43%, P < 0.01).
  • Older age (>70 years) was a common factor in AF development across both groups.

Conclusions:

  • Restarting beta blockers post-CABG effectively controls the incidence and severity of atrial fibrillation.
  • Early rhythm conversion is enhanced with postoperative beta blocker therapy.
  • The study reinforces the association between advanced age and increased risk of AF after cardiac surgery.
