Abstract

AIMS: Persistent atrial fibrillation (AF) often recurs after direct current electrical cardioversion (ECV). As several experimental and clinical studies suggest that n-3 polyunsaturated fatty acids (PUFAs) may have antiarrhythmic properties even at the atrial level, we aimed to evaluate whether oral supplementation with PUFAs, in addition to conventional antiarrhythmic drugs, could reduce the recurrence rate of the arrhythmia after ECV of persistent AF. METHODS AND RESULTS: Two hundred and four patients (mean age 69.3 years, 33% females) with persistent AF were randomly assigned to receive 3 g/day of PUFAs until ECV and 2 g/day thereafter (104 patients) or placebo (100 patients) for 6 months, beginning at least 1 week before ECV. Selection of conventional antiarrhythmic prophylaxis was left to local medical advice. The cardiac rhythm was assessed by both trans-telephonic monitoring and clinical visits. Primary end-point was the recurrence rate of AF. Sinus rhythm was restored, either spontaneously or after ECV, in 187 patients (91.7%); 95 patients (91.4%) on PUFAs and 92 patients (92.0%) on placebo (P=not significant). AF relapsed in 56 (58.9%) of the PUFAs patients and in 47 (51.1%) of the placebo patients (P=0.28). The mean time to AF recurrence was 83±8 days in the PUFAs group and 106±9 days in the placebo group (P=0.29). CONCLUSION: Our results do not support the hypothesis that, in patients undergoing ECV of chronic persistent AF, supplementation with PUFAs in addition to the usual antiarrhythmic treatment reduces recurrent AF.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
