Terapia com estrogênio após a menopausa reduz o risco de calcificação na artéria coronária

Abstract: Em recente estudo (WHI Coronary-Artery Calcium Study -WHI-CACS), Manson et al. (2007) 1 avaliaram em mulheres após a menopausa (entre 50 e 59 anos) o impacto do estrogênio conjugado eqüino (0,625mg/dia) sobre o risco de calcificação de artérias coronárias. Sabidamente, calcificações coronárias se correlacionam positivamente com a extensão da placa de ateroma e a ocorrência de eventos cardiovasculares. Nesse estudo, foi observado de forma clara e surpreendente significativa redução (42%, p=0.03) no número de… Show more

“…Women are protected from atherosclerosis during reproductive age, since estrogen lowers low-density cholesterol (LDL) levels and increases high-density cholesterol (HDL) levels, slowing down the atherosclerotic process. 10 , 25 This protection occurs because LDL cholesterol is lighter and easily adheres to the endothelium of the arteries, causing obstructions throughout the individual’s life, while HDL, being heavier, is more concentrated in the central flow of the vessel, which prevents it from adhering to the endothelium of the arteries, thereby avoiding the formation of atheromatous plaques. Dyslipidemia, although a cause of artery obstruction, is not directly related to calcification.…”
