  Purpose

The purpose of this study is to determine the effect of n-3 PUFAs in addition to amiodarone and renin-angiotensin-aldosterone system (RAAS) inhibitors on the maintenance of sinus rhythm after electrical conversion in patients with persistent Atrial fibrillation (AF).

Primary Outcome Measures:
  • Probability of Maintenance of Sinus Rhythm at One-year Follow up.(Number of Patients Who Maintained Sinus Rhythm) [ Time Frame: one year ] [ Designated as safety issue: No ]
    Sinus Rhythm maintenance means no Atrial Fibrillation recurrence at one-year follow up. Patients with successful electrical cardioversion (DCCV)underwent weekly clinical and electrocardiographic controls for the first three weeks following cardioversion. Subsequently, follow up visits with performance of clinical evaluation, ECG, and a 24-hour Holter monitoring were performed at 1, 3, 6 and 12 months after DCCV.


Secondary Outcome Measures:
  • The Mean Time to a First Recurrence of AF and the Rate of AF Recurrence [ Time Frame: 1, 3 and 6 months ] [ Designated as safety issue: No ]
    The mean time to a first recurrence of AF; and the rate of AF recurrence at 1, 3 and 6 months.

Arms Assigned Interventions
Active Comparator: n-3 PUFAs Drug: n-3 PUFAs
1.0 g of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) in the average ratio EPA/DHA of 0.19:1.5, one capsule twice a day
Other Name: OMACOR
Drug: RASS inhibitors and/or RAS blockers
Patients on ACE-Is or ARBs were continued on the same agent. In those who were not on therapy, an ACE-I or an ARB was started. In all patients, an effort was made to achieve the highest tolerated dose.
Other Name: renin-angiotensin-aldosterone system inhibitor
Drug: Amiodarone
Patients on amiodarone were continued at a maintenance dose of 200 mg daily, whereas those who were not taking amiodarone were started at a dose of 400 mg daily for 1 week and then continued on a maintenance dose of 200 mg daily.
Other Name: Amiodarone
Placebo Comparator: placebo Drug: Placebo

Drug: Amiodarone
Patients on amiodarone were continued at a maintenance dose of 200 mg daily, whereas those who were not taking amiodarone were started at a dose of 400 mg daily for 1 week and then continued on a maintenance dose of 200 mg daily.

Detailed Description:

Atrial fibrillation (AF) is the most common sustained arrhythmia and represents an increasing burden on the healthcare system. Treatment of AF remains controversial. In patients on antiarrhythmic therapy, the one-year relapse rates of AF after cardioversion ranges from 44% to 77% at one year and amiodarone appears to the be the most effective in maintaining sinus rhythm.Over the last few years, a growing amount of evidences has supported the protective effects of n-3 PUFAs in preventing ventricular arrhythmias and reducing the risk of sudden cardiac death. Furthermore, in the last years, the interest for their possible beneficial role in AF prevention has been increasing.We hypothesized that the administration of n-3 PUFAs could reduce the AF recurrence rate more than amiodarone plus RAAS inhibitors in patients with persistent AF. Therefore the present study aims to evaluate the role of n-3 PUFAs in the prophylaxis of AF recurrences after DCCV in addition to amiodarone and RAS blockers therapy in patients with persistent AF.
