Popis: Data on the relationship between omega-3 fatty acid (n-3 FA) therapy with atrial fibrillation (AF) have been inconsistent. We investigate the association between n-3 FA and risk for AF by pooling data from available large, cardiovascular outcome trials. We performed a systematic search on PubMed and Embase for studies on n-3 FA with AF as an outcome measure. Large (≥ 1000 participants) randomized controlled trials with ≥ 1-year follow-up period were included. The association between n-3 FA and risk of AF or stroke was assessed. Mantel–Haenszel random effects model was used to calculate risk ratios (RR) with 95% confidence intervals (CI). We then performed meta-regression to evaluate effect on AF by dose of n-3 FA therapy. A total of 8 randomized control trials encompassing 83,112 participants were included in the meta-analysis. Of these, five trials assessed a lower dose of n-3 FA (≤ 1 g daily, n = 61,096) while 3 trials assessed a higher dose (> 1 g daily, n = 22,016). In meta-analysis, a significant association was noted between n-3 FA treatment and risk of AF (4.0% vs 3.3%; RR 1.24, 95% CI 1.11–1.38, p = 0.0002). There was a modest but still significant association in the lower dose (n-3 FA ≤ 1 g daily) sub-group (RR 1.12, 95% CI 1.04–1.21, p = 0.004) and stronger association in the higher dose (n-3 FA > 1 g daily) sub-group (RR 1.51, 95% CI 1.26–1.80, p
