Early Antiarrhythmic Therapy Is No Better than Rate Control Therapy Alone for Suppression of Atrial Fibrillation After Cardiac Surgery

Background: Despite recent advances in therapy for atrial fibrillation (AF) following cardiac surgery, the potential superiority of antiarrhythmics over rate control therapy for suppression of AF has not been convincingly demonstrated. We sought to determine whether early treatment of AF following cardiac surgery with antiarrhythmics improves clinical outcome, as measured by recurrence rate, length of stay, and adverse events.
