[Vasopressin and renin-aldosterone system in patients with arterial hypertension].

Levels of vasopressin, aldosterone and plasma renin activity were studied in patients with arterial hypertension. It is shown that progression of the disease dysregulates neurohormonal systems responsible for arterial pressure control. Activation of vasoconstrictive systems of vasopressin and aldosterone synthesis involved in retention of fluid in the body goes in parallel to lowering of renin secretion. The above changes may be considered as a compensatory mechanism of arterial hypertension stabilization.
