The effects of supplementation with omega-3 polyunsaturated fatty acids on cardiac rhythm: anti-arrhythmic, pro-arrhythmic, both or neither? it depends… B. Rauch and J. Senges Frontiers in Physiology, 2 April 2012, doi: 10.3389/fphys.2012.00057
In this overview, Rauch and collaborators discuss the controversial place of Omega-3 supplementation in the prevention of cardiovascular disease. Due to the mixed results of several studies, its place is not well defined at this moment. After extensively reviewing the literature on this topic, Rauch et al. conclude that the effect of Omega-3 supplementation may depend on the background diet and the pre-existent intake of fish oil. Also, the current treatment for ischemic heart disease probably reduces the positive effects of Omega-3 supplements. The anti-arrhythmic effect is probably greater in ischemia-induced arrhythmias, but is reduced when patients are optimally treated with contemporary medication. This is an interesting article for those of you who want to know the details of this controversial subject.
