Resumen

VILLALOBOS, M.ª E. et al. Similarities, differences and agonisms of pleiotropic effects of statins and omega-3 fatty acids. Nutr. Hosp. [online]. 2010, vol.25, n.6, pp.889-909. ISSN 0212-1611.

This paper compares the pleiotropic effects of statins and omega-3 fatty acids (n-3 PUFA) in treating and preventing cardiovascular disease (CVD) and deals with the possible interactions of those compounds. Statins represent one of the most important discoveries to have been made in the field of cardiovascular medicine in recent decades. Their beneficial cardiovascular effects, which have reduced the number of fatal events in patients with atherosclerosis, encompass more than their ability to lower cholesterol levels. The pleiotropic effects of statins involve their anti-inflammatory and antiplatelet properties and their ability to normalize endothelial function. In addition, these drugs may display antiarrhythmic activity, improve insulin sensitivity and counteract hypertension and obesity. The low rate of coronary disease documented in Eskimos corroborates the cardioprotective effects of the n-3 PUFA eicosapentaenoic (EPA) and docosahexaenoic acids beyond their hypolipemic effects. The reduction of CVD-related deaths attributable to the action of α-linolenic fatty acid appears to be related to its strong antiarrhythmic properties. In addition, as a precursor of EPA and this last fatty acid of thromboxane A3, prostacyclin I3, serie-3 prostaglandines and serie 5-leukotrines and inhibitor/modulator of thromboxane A2, prostacyclin I2, serie-2 prostaglandines and serie 4-leukotrienes formation, the α-linolenic acid may reduce inflammation and thrombogenesis. As results of some studies suggest that the combined use of statins and n-3 PUFA improves cardiovascular protection and reduces the CVD-related mortality rate; the paper also reviews the possible synergism between both groups of compounds on CVD treatment and concludes that clear benefits may be obtained.
