“…Several studies have demonstrated the association between the serum levels of high-density lipoproteins (HDL-c) and cardiovascular disease. Decreased HDL-c levels are present in approximately 10.0% of the population and these individuals could be incapable of effectively eliminating the cholesterol excess from the vascular walls, contributing to the inflammatory process and characterizing the pathogenesis of atherosclerosis in its initial phases, in addition to having anti-atherogenic effects, such as anti-oxidant effects and others 34 .…”

“…These habits (smoking, alcoholism, sedentariness, cardiovascular antecedents and obesity) in association to high LDL rate and low HDL rate may drive to atherosclerotic disease aggravation. Second some authors [17], the high atherogenic lipoprotein indexes, including Very Low Density Lipoprotein (VLDL) and the LDL, are in general feature connected to low HDL indexes. The HDL have high anti atherogenic potency, mainly due to its capacity to transport lipids, specially cholesterol ester from peripheral tissues to the liver through the reverse cholesterol transport way (RCT), apart from offering anti-oxidised protection, mediate the cholesterol efflux, inhibit the expression of cellular adhesion molecules and leukocyte activation.…”

“…Gou et al 40 observaram redução do tamanho da HDL em indivíduos hipertrigliceridêmicos do sexo masculino em comparação ao grupo controle (normolipêmicos). A HDL protege contra a aterosclerose a partir de diversos mecanismos, dentre eles: (a) possui na sua constituição enzimas antioxidantes -paraoxonase e glutationa peroxidase -que inibem a oxidação de lipoproteínas e lipídios; (b) remove e elimina o excesso de colesterol via apolipoproteína AI (apo AI) e lecitina colesterol aciltransferase (LCAT); (c) suprime resposta inflamatória via captação e eliminação de endoxinas e fosfolipídios oxidados por ação da apo AI e antioxidação da LDL; (d) ação antitrombótica através da atividade da enzima acetil-hidrolase do fator ativador de plaquetas (PAF-AH), que é potente inibidora da agregação plaquetária; (e) pela capacidade de remover o colesterol de macrófagos ligados ao endotélio, processo dependente de proteínas específica conhecida como ATP binding cassete transporter A1 (ABCA-1), iniciando o transporte reverso de colesterol 41 . No processo aterosclerótico a HDL possui "papel" importante por limitar a modificação ou oxidação de lipídios e/ou lipoproteínas, além de remover o colesterol e fosfolipídios dos tecidos periféricos retornando-os ao fígado para ser excretado pela via biliar e fecal -processo conhecido como transporte reverso 30 .…”
