Systemic Microvascular Function in Patients With Resistant Hypertension After Renal Sympathetic Denervation

NCT03243045

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.
