Studies on the Mechanisms of Glucocorticoid Hypertension in Humans

Abstract

Hypertension is a common feature of both Cushing's syndrome, which is relatively rare, and iatrogenic steroid administration, which is much more common. Cardiovascular mortality and morbidity are very significant in patients with both naturally occurring and iatrogenic disease. The mechanism of glucocorticoid induced hypertension in man remains undefined. Contrary to previous notions, it does not reflect urinary sodium retention or volume expansion. Increased pressor responsiveness may be an important contributor to the rise in blood pressure.
