Molecular and clinical investigations in patients with low-renin hypertension

Abstract

Interactions between the renin-angiotensin-aldosterone system and other mechanisms determining sodium balance are important in the pathophysiology of hypertension. Low-renin hypertension is a common type of resistant hypertension and is often associated with increased sodium retention. The importance of investigation, factors determining renin and aldosterone levels, and drug therapies in low-renin hypertension are reviewed.
