  Fascinating. > It is unclear how omega-3 fatty acids increase the AF risk. Omega-3 fatty acids stabilize the cardiac membrane and protect against arrhythmias, including ventricular arrhythmias, through both direct electrophysiologic actions and positive effects on biological processes involved in atrial remodeling. However, omega-3 fatty acids have direct effects on the activity of cardiac calcium, sodium, and potassium ionic currents, which can alter the duration of the ventricular action potential. Therefore, omega-3 fatty acids may promote re-entrant arrhythmias, despite being anti-arrhythmic in therapeutic conditions. Several previous studies have evaluated the electrical characteristics of the ventricular wall; few studies have evaluated how omega-3 fatty acids influence the atria.

    EILI5? How compelling is this study against Omega3?

      It sounds to me like that short quote is saying (paraphrasing here) that 'studies seems to show omega-3 is beneficial, but theoretically apart from the beneficial mechanisms there could be a harmful mechanism so we're not sure why we don't see that happening'

      There's been a fair bit of research people who have diets rich in Omega 3, have better cardiovascular health. There is no real reliable study's that show consistent benefits from Omega 3 supplements however.
