“…A number of animal and clinical studies have shown that DHA-enriched diets can increase plasma cholesterol associated with low- and high-density lipoproteins [ 41 43 ]. Hypercholesterolemia has been associated with many vasculature abnormalities including endothelial dysfunction, decreased vascular reactivity, and enhanced expression of adhesion molecules [ 44 , 45 ]. Cell culture studies suggest several mechanisms by which cholesterol may be pro-inflammatory and some of these appear to be analogous to the effects of dietary SFA.…”

“…1 However, recent work in animal models highlighted that these complex pathophysiological mechanisms associated with arterial wall cholesterol level, lipid peroxidation, and endothelial dysfunction are not correlated with plasma total cholesterol (TC) level. 2 The mechanism by which oxidative stress and serum cholesterol causes cardiovascular disease (CVD) therefore remains to be clarified. 3 An association between 8-hydroxy-2-deoxy-guanosine (8-OHdG) and endothelial dysfunction have been proposed.…”

“…A redução na concentração da LDL -colesterol promove benefícios no infarto do miocárdio já que o aumento dessa lipoproteína no plasma é considerado um importante fator de risco (98) . No infarto do miocárdio o aumento da LDL -colesterol aumenta a produção de ERONS pela célula endotelial com indução das moléculas de adesão, estimulo à proliferação e migração da célula muscular lisa vascular, aumento da peroxidação lipídica e da ativação das metaloproteinases e, alteração da atividade vasomotora do vaso devido a diminuição na biodisponibilidade do NO (99) . Embora, a LDL -colesterol esteja na circulação protegida pelos antioxidantes plasmáticos, acredita-se que uma pequena porção dessa lipoproteína seja modificada ainda na circulação e que a oxidação continue após sua entrada na íntima arterial, ambiente pro -oxidante, com ausência de antioxidantes plasmáticos (93) .…”
