title: 10. Hypertension. A comparison of the effects of angiotensin II infusion and variations in salt intake on plasma aldosterone levels in normal subjects, patients with essential hypertension and patients with hyperaldosteronism.
abstract: Infusion of angiotensin II into a patient with dexamethasone-suppressible hyperaldosteronism caused a brisk increase in plasma aldosterone concentration. In this behaviour, the patient resembled those patients with idiopathic hyperaldosteronism rather than those with tumorous primary hyperaldosteronism. Sodium depletion of a small group of patients with mild essential hypertension elicited a spectrum of increases in plasma aldosterone levels ranging from zero to normal. Angiotensin II infusion in both sodium replete and deplete states also caused variable aldosterone responses. These results suggest that the derangement of adrenal function in this condition varies continuously in severity.
