Abstract
PURPOSE OF REVIEW: Men and women differ in the prevalence, pathophysiology and control rate of hypertension in an age-dependent manner. The renal endothelin system plays a central role in sex differences in blood pressure regulation by control of sodium excretion and vascular function. Improving our understanding of the sex differences in the endothelin system, especially in regard to blood pressure regulation and sodium homeostasis, will fill a significant gap in our knowledge and may identify sex-specific therapeutic targets for management of hypertension. RECENT FINDINGS: The current review will highlight evidence for the potential role for endothelin system in the pathophysiology of hypertension within three female populations: (i) postmenopausal women, (ii) women suffering from preeclampsia, or (iii) pulmonary arterial hypertension. Clinical trials that specifically address cardiovascular and renal diseases in females under different hormonal status are limited. Studies of the modulatory role of gonadal hormones and sex-specific mechanisms on critically important systems involved, such as endothelin, are needed to establish new clinical practice guidelines based on systematic evidence.
