[Hormonal disorders in borderline arterial hypertension].

Measurements of blood plasma ACTH, hydrocortisone, STH, somatostatin, insulin, glucagon levels and plasma renin activity in 70 patients with borderline hypertension (BAH) and in 20 normal male subjects have revealed increased ACTH, hydrocortisone, and somatostatin levels, elevated plasma renin activity, and reduced STH and insulin levels in the patients. A possible role of the pressor hormone system activation in the pathogenesis of borderline arterial hypertension and in BAH transformation into essential hypertension is discussed.
