Condition atrial fibrillation
Treatments omega 3 (n-3 pufa), placebo
Phase phase 3
Sponsor Fundacion GESICA
Start date January 2008
End date July 2011
Trial size 1600 participants
Trial identifier NCT00597220, FORWARD


To demonstrate that in patients with persistent atrial fibrillation who had recovered normal sinus rhythm and treated with the best recommended therapies, the addition of 1 gram / daily of n-3 PUFA is superior to the corresponding placebo for the maintenance of normal sinus rhythm at one year of follow up.

Additional Information

Official title Randomized, Prospective, Placebo-controlled, Multi-center Study to Test the Efficacy of n-3 PUFA for the Maintenance of Normal Sinus Rhythm in Patients With Persistent Atrial Fibrillation
Description Atrial fibrillation (AF) impose a substantial and growing economic burden on health care expenditures. In patients with persistent AF, there are fundamentally two ways to manage the arrhythmia: to restore and maintain sinus rhythm (rhythm control) or to allow AF to continue and ensure that the ventricular rate is controlled (rate control). As it has been stated, it goes without saying that if we could prevent atrial fibrillation (AF) or restore and maintain sinus rhythm in patients suffering from persistent AF, without any penalties due to the unwanted effects of drugs or incomplete suppression of AF and its thromboembolic complications, every physician would do so. Current strategies however, are limited to achieve such desirable goal. In the last years a growing amount of evidence and attention regarding the cardio-protective role of Omega 3 fatty acids (n-3 PUFA) became progressively clear and appealing. Epidemiological studies and randomized controlled trials confirms the role of n-3 PUFA in reducing all cause mortality and cardiovascular events mostly in patients at high cardiovascular risk. These effects seems to be mediated mostly by an anti-arrhythmogenic effect. Basic science confirms and extended clinical observations regarding the antiarrhythmogenic effect of these compounds. Recently both basic research and clinical science suggested a role of n-3 PUFA for the prevention and treatment of supraventricular arrhythmias, particularly AF. The purpose of the study is to show that the addition of n-3 PUFA on the top of the best recommended therapies can improve the maintenance of normal sinus rhythm in patients with persistent atrial fibrillation.
