Abstract

Several observational and experimental studies show the beneficial effects of ω-3 poly-unsaturated fatty acids (PUFA) in cardiovascular disease. The results from such studies justify supplementation of ω-3 PUFA in primary and secondary prevention of several clinical conditions, including coronary heart disease, sudden cardiac death and heart failure. Supplementation of ω-3 PUFA is also indicated as monotherapy in the treatment of hypertriglyceridemia. Analysis of their biological actions suggests a variety of anti-arrhythmic, anti-thrombotic, anti-atherosclerotic and antiinflammatory mechanisms underlying their clinical benefits.
