High level of adrenal catecholamines in hypertensive subjects with impaired renal function.

Contents of catecholamines were determined in 46 adrenal specimens removed from subjects without adrenal disease. These subjects were allocated in a retrospective conformation to two points: one for renal function and another for blood pressure. Based on the findings, elevated adrenal catecholamines associated with hypertension appear to impair renal function in man.
