Algunas consideraciones de la disfunción endotelial en pacientes con hiperprolactinemia

a review of the publications available of current situation on the subject related to endothelial dysfunction in patients with hyperprolactinemia: existence, production mechanisms and consequences. taking into account that the hyperprolactinemia has a new approach related to endothelial dysfunction authors made present review. above mentioned dysfunction is a alteration in the vascular relaxation provoked by decrease of relaxation factors derived from endothelium, mainly the nitric oxide, which cause an increase of vasoconstrictor stimulus with a pro-thrombotic trend of vasculature. the insulin resistance acts as a major factor of endothelial dysfunction associated or not with diabetes mellitus. until now, the hyperprolactinemia status is associated with disorders of the glucose tolerance (decreased glucose tolerance with hyper-insulinemia). there is endothelial dysfunction in women with hyperprolactinemia and may be due to its relation to insulin resistance, to decrease of estrogens and to the own hyperprolactinemia. also, there are inflammation's markers (the c-reactive protein) high in patients with this disease. the hyperprolactinemia is associated with the insulin resistance, the endothelial dysfunction and the low degree of inflammation, parameters determinant in the atherosclerosis process, thus, this disease may be a predisposing factor of the atherosclerosis becomes risk of cardiovascular morbidity and mortality.
