Introduction and methods

Omega-3 fatty acids (O3FA) are being utilized to reduce the risk of CV events in adults at high risk for, or with established CVD and elevated triglycerides. However, safety results of CVOTs investigating O3FA supplementation showed a higher incidence of AF events in patients taking O3FA, compared to those on placebo. This meta-analysis investigated whether O3FA supplementation, compared with placebo, is associated with an increased risk of incident AF.

Five RCTs were included in this study-level meta-analysis: REDUCE-IT, ASCEND, R&P, STRENGTH and OMEMI [1-5]. The primary endpoint of the analysis was onset of AF.

Main results

Conclusion

This meta-analysis of five RCTs showed that O3FA supplementation, compared to placebo, is associated with an increased risk of incident AF in patients with elevated triglycerides and at elevated CV risk.
