Aims This study aimed to assess whether enalapril could improve cardioversion outcome and facilitate sinus rhythm maintenance after conversion of chronic atrial fibrillation (AF). Methods and results Patients with chronic AF for more than 3 months were assigned to receive either amiodarone (200 mg orally 3 times a day; group I: n=75) or the same dosage of amiodarone plus enalapril (10 mg twice a day; group II: n=70) 4 weeks before scheduled external cardioversion. The end-point was the time to first recurrence of AF. In 125 patients (86.2%), AF was converted to sinus rhythm. Group II had a trend to a trend to a lower rate of immediate recurrence of AF than group I did (4.3% vs 14.7%, P=0.067). Kaplan-Meier analysis demonstrated a higher probability of group II remaining in sinus rhythm at 4 weeks (84.3% vs 61.3%, P=0.002) and at the median follow-up period of 270 days (74.3% vs 57.3%, P=0.021) than in group II. Conclusion The addition of enalapril to amiodarone decreased the rate of immediate and subacute arrhythmia recurrences and facilitated subsequent tong-term maintenance of sinus rhythm after cardioversion of persistent AF.
