Should not yet alter hypertension management; leaves open mechanistic questions in low-renin states.
Does sodium depletion alter plasma renin activity and aldosterone excretion in hypertensive patients with low plasma renin activity compared to normotensive subjects?
Hypertensive patients with low plasma renin activity exhibit a blunted renin and aldosterone response to sodium depletion, alongside differences in sodium and potassium handling.
Helmer et al. (1968) studied this question.
