Omega-3 fatty acids: role in metabolism and cardiovascular disease


Gerber, Philipp A; Gouni-Berthold, Ioanna; Berneis, Kaspar (2013). Omega-3 fatty acids: role in metabolism and cardiovascular disease. Current Pharmaceutical Design, 19(17):3074-3093.

Abstract

The inverse association of cardiovascular risk with intake of omega-3 polyunsaturated fatty acids was suspected early in populations that are known to have a high consumption of fish and fish oil. Subsequent cohort studies confirmed such associations in other populations. Further evidence of possible beneficial effects on metabolism and cardiovascular health was provided by many studies that were able to show specific mechanisms that may underlie these observations. These include improvement of the function of tissues involved in the alterations occurring during the development of obesity and the metabolic syndrome, as adipose tissue, the liver and skeletal muscle. Direct action on the cardiovascular system was not only shown regarding vascular function and the formation of atherosclerotic plaques, but also by providing antiarrhythmic effects on the heart. Data on these effects come from in vitro as well as in vivo studies that were conducted in animal models of disease, in healthy humans and in humans suffering from cardiovascular disease. To define prophylactic as well as treatment options in primary and secondary prevention, large clinical trial assessed the effect of omega-3 polyunsaturated fatty acids on end points as cardiovascular morbidity and mortality. However, so far these trials provided ambiguous data that do allow recommendations regarding the use of omega-3 polyunsaturated fatty acids in higher dosages and beyond the dietary advice of regular fish intake only in few clinical situations, such as severe hypertriglyceridemia.
