The aim of this discussion is to outline briefly how the measurement of plasma renin levels, or quantitation of the renin-angiotensin pressor effect, can be of value in the treatment of essential hypertension and in the diagnosis of surgically curable hypertension.

Before reviewing the role of the renin-angiotensin system in clinical hypertension, it is necessary to understand the close physiologic link that exists between this hormonal system and body sodium and water
