Aldosterone Secretion in Hypertension

tion of aldosterone was measured in 44 hypertensive patients. The method used for determining aldosterone secretion rate appeared to give valid results even in patients with renal failure. Hyperaldosteronism was uncommon in "benign" hypertension; its presence should suggest the pos-sibility of curable hypertension resulting from adrenal cortical adenoma, bilateral adrenal cor-tical hyperplasia, or renal artery disease. How-ever, hyperaldosteronism was also uncommon in patients with renal artery disease. In three pa-tients previously untreated with antihypertensive medication, hyperaldosteronism disappeared after blood pressure was controlled
