Carvedilol Versus Metoprolol for the Prevention of Atrial Fibrillation After Off-Pump Coronary Bypass Surgery

Summary

Postoperative new-onset atrial fibrillation (AF) is the most common complication stemming from coronary artery bypass graft surgery, and is associated with increased early and late mortality risk. Standard guidelines recommend β blockers for the prevention of AF; however, no prospective study has compared the relative efficacy of β-blocking agents. We hypothesize that carvedilol, a non-selective adrenergic blocker with both anti-inflammatory and antioxidant properties, is more effective than metoprolol, a conventional β1-selective antagonist, in suppressing new-onset AF following off-pump coronary bypass surgery. We have designed the Carvedilol or Metoprolol Post-Revascularization Atrial Fibrillation Controlled Trial (COMPACT) to test our hypothesis in a multi-center, open-label, and randomized controlled trial.
