What we need to know about renal nerve ablation for treatment of hypertension and other states of sympathetic overactivity

Abstract

Renal nerves are key players in the regulation of kidney function and blood pressure control. Targeting the neurogenic mechanisms underlying hypertension and cardiac and renal disease has been attempted by means of surgical and pharmacologic approaches and most recently by catheter-based interventions aimed at disrupting renal sympathetic nerve traffic. The recent developments in the area and the relevant questions that need to be addressed to advance the field further are briefly reviewed in this article.
