OBJECTIVE In the setting of normal sodium (Na) intake, many patients with hypertension have inappropriately elevated plasma aldosterone (Aldo) levels and may be at increased risk for tissue damage. Moreover, other adrenocortical steroids, including endogenous ouabain can stimulate tissue damage. As endogenous ouabain is often elevated in chronically Na-loaded states, is a vasoconstrictor, raises blood pressure (BP), and also promotes tissue fibrosis, we investigated the extent to which plasma Aldo and endogenous ouabain were coelevated among naive hypertensive patients (NHP). We also investigated the impact of an acute salt load on these steroids, BP, and renal function. METHODS NHP (590) were grouped in tertiles based on their baseline plasma Aldo (mean ± SEM first 7.59 ± 0.18, versus third 24.15 ± 0.31 ng/dl). Baseline plasma renin activity (2.4 ± 0.1 versus 1.2 ± 0.1 ng/ml per h, P
