Quick takeaways

  • Omega-3 fatty acids may be associated with an increased risk of atrial fibrillation in high-risk populations, but observational studies have found a protective effect of Omega-3s against atrial fibrillation.
  • DHA, a component of Omega-3s, has shown potential in reducing plaque progression, improving arterial compliance, lowering blood pressure, reducing vulnerability to atrial fibrillation, improving periodontal disease, and increasing LDL size, making it a beneficial supplement alongside EPA for balanced health.

Omega-3s and AFib: New Risk Associated with EPA

A new warning has been issued about the association of EPA, or Omega-3s, with atrial fibrillation (AFib). AFib is a common arrhythmia that can be triggered by abnormalities in the heart's rhythm. While preclinical data initially suggested that Omega-3s may have anti-arrhythmic effects, studies on high-risk populations have shown a pro-arrhythmic association. However, observational studies have found a protective effect of Omega-3s, particularly DHA, against AFib. The European Medicines Agency has recently added a warning label to Omega-3 ethyl ester products. More research is needed to fully understand the effects of Omega-3s on AFib risk.
