Omega-3s for Atrial Fibrillation

First, a video that a very special friend of mine shared with me. I thought it was pretty damn funny, although I'd have to say this dude has too much time on his hands.
 
Atrial fibrillation (AF) is considered the most common irregular heart beat (termed arrhythmia), and treatment options are limited, with the main intervention being that patients are put on warfarin to prevent blood clotting associated with an irregular heart rhythm (click HERE to read a post on the evils of warfarin, and HERE for another post on its long anticipated replacement).

Interestingly, omega-3s have been suggested to reduce the risk of blood coagulation (although this is debated), so getting enough of these fatty acids may not only help reduce the risk of AF, but also the risk of coagulation associated with AF.

So, here's a study that seems to confirm what was previously found regarding omega-3 fatty acids and AF. Recently published data from this study indicated that the highest average levels of omega-3 fatty acids were associated with a 29% reduction in the risk of AF when compared against the lowest average levels.

The effects seemed more pronounced with DHA, than EPA, and the data suggested it was the percent of omega-3s in relation to total fatty acids, that carried the biggest effect (rather than the actual amounts of DHA and EPA).
