About
It has been proposed that the modulation of the activity of the sympathetic nervous system, through renal sympathetic denervation, besides reducing blood pressure, would promote an improvement in vascular reactivity and consequent improvement of macro and microcirculation.
The present study aimed to investigate the influence of the renal sympathetic denervation on the skin microvascular function of patients presenting with resistant arterial hypertension.
Full description
Arterial hypertension is still a serious public health problem with considerable social and economic impact. Arterial hypertension is the result from a complex interaction between environmental and genetic factors that initiate and perpetuate elevated blood pressure. Studies show that about 10% of patients undergoing treatment have resistant hypertension, defined as high blood pressure refractory to at least three antihypertensive drugs. It is known that the sympathetic nervous system plays a fundamental role in the pathophysiology of hypertension, contributing to metabolic and vascular changes. The sympathetic nervous system has also a major role in the pathophysiology of arterial hypertension. Arterial hypertension has also been associated with functional microcirculatory alterations as well as systemic microvascular endothelial dysfunction in hypertensive patients, confirmed by different microcirculatory flowmetry techniques. In this context, it has been proposed that the modulation of the sympathetic nervous system through renal sympathetic denervation, besides reducing blood pressure, would promote an improvement in vascular reactivity and consequent improvement of macro and microcirculation.
The present study aimed to investigate the influence of the renal sympathetic denervation on the skin microvascular function of patients with resistant hypertension.
