Abstract

Aldosterone secretion rate, metabolic clearance rate, and/or plasma concentration were determined in 16 patients with benign, uncomplicated essential hypertension and compared with those of control subjects. The mean metabolic clearance rate of aldosterone in 10 patients was significantly (P < 0.001) lower (mean 867 liters of plasma/day per m2 ±270 SD) than in a group of 7 healthy subjects (mean 1480 liters/day per m2 ±265 SD). Secretion rates in 13 patients (including the 10 already mentioned) tended to be low (83 ±43 vs. 109 ±54 μg/day) and plasma concentrations tended to be high (13.6 ±4.6 vs. 7.5 ±4.8 ng/100 ml), but neither of these differences was statistically significant.
