Papel protetor dos estrogénios na aterosclerose

Papel protetor dos estrogénios na aterosclerose

Abstract

A aterosclerose e as suas complicações são uma das principais causas de mortalidade nos países desenvolvidos em ambos os sexos. Embora as mulheres apresentem menor incidência de doenças cardiovasculares do que os homens da mesma idade, essa diferença desaparece após a menopausa. Apesar de ser evidente a contribuição das hormonas esteroides sexuais para as diferenças que existem entre os sexos no que diz respeito ao sistema cardiovascular, é necessário investigar melhor as causas dessas diferenças para se poder personalizar estratégias de prevenção, diagnóstico e tratamento de doenças cardiovasculares. Os estrogénios endógenos exercem diversas funções reguladoras através da ativação de recetores de estrogénios, podendo ter um efeito terapêutico na redução do risco de doenças cardiovasculares, incluindo a aterosclerose. A utilização da terapêutica hormonal de substituição após a menopausa é um dos assuntos clínicos mais controversos nas mulheres, uma vez que estão descritos benefícios, nomeadamente relacionados com a saúde cardiovascular, mas também riscos associados, tendo-se verificado nos últimos anos uma redução da sua prescrição da terapêutica. Porém, tem-se estudado as vantagens associadas à individualização da terapêutica, variando o tipo de substâncias ativas, dose, via de administração, duração e idade de início da implementação. Com esta monografia, pretende-se investigar o papel protetor dos estrogénios na aterosclerose e de que forma a menopausa influencia o aumento da incidência de doenças cardiovasculares nas mulheres, assim como o balanço do benefício/risco da terapêutica hormonal de substituição após a menopausa.

Atherosclerosis and its complications are one of the leading causes of mortality in developed countries in both genders. Although women report a lower incidence of cardiovascular disease than men of the same age, this difference disappears after menopause. Despite the clear contribution of steroid hormones to the differences between the genders in regard to the cardiovascular system, it is necessary to investigate the causes of these differences in order to customize strategies for prevention, diagnosis and treatment of cardiovascular diseases. The endogenous estrogens exert several regulatory functions through the activation of estrogens receptors and may have a potential therapeutic effect in reducing the risk of cardiovascular diseases, including atherosclerosis. The use of hormone replacement therapy after menopause is one of the most controversial clinical issues in women, since there are known benefits particularly related to cardiovascular health, but also associated risks, and in recent years there has been a reduction in its prescription. However, the advantages associated with the individualization of therapeutics are being studied, varying the type of active substances, dosage, route of administration, duration and age of onset of the implementation of the therapy. With this monograph, it is intended to investigate the protective role of estrogens on atherosclerosis and how menopause affects the increased incidence of cardiovascular disease in women, as well as the benefit/risk balance of the hormone replacement therapy after menopause.
