Key result
Low renin hypertension patients with marked suppression of plasma renin activity exhibited inappropriately elevated plasma aldosterone levels compared to normal subjects.
Why the study?
How do plasma renin activity and plasma aldosterone dynamics differ between normal subjects and patients with low renin hypertension during upright posture and varying sodium diets?
Population
10 normal subjects and 12 patients with low renin hypertension (LRH)
Comparison
6 hours of upright posture on both normal and… vs Normal subjects
Design
Cross-sectional
Follow-up
6 hours

Highlights low-renin hypertension subset with inappropriate aldosterone elevation; leaves open distinct, treatable phenotype pending prospective studies.
Observational (n=22)
How do plasma renin activity and plasma aldosterone dynamics differ between normal subjects and patients with low renin hypertension during upright posture and varying sodium diets?
Low renin hypertension patients can be divided into two subgroups based on the degree of plasma renin activity suppression, which corresponds to different ratios of plasma aldosterone to plasma renin activity.
Ré et al. (1978) conducted an observational in Low renin hypertension (n=22). Low renin hypertension vs. Normal subjects was evaluated on Plasma renin activity (PRA) and plasma aldosterone (PA) dynamics. Low renin hypertension patients with marked suppression of plasma renin activity exhibited inappropriately elevated plasma aldosterone levels compared to normal subjects.
