[Importance of determining the renin activity in the blood plasma of the renal veins in symptomatic hypertension]. / Znachenie opredeleniia aktivnosti renina v plazme krovi pochechnykh ven u bol'nykh s simptomaticheskoi gipertenziei.

In patients with vasorenal hypertension blood plasma renin activity was always higher on the side of the lesion than on the contralateral side, whereas in patients with nephrogenic hypertension and coarctation of the aorta this value was within physiological norm. After reconstructive operations in vasorenal hypertension (in an unilateral lesion) a hypotensive effect was produced when the ratio of blood plasma renin activity on the side of the lesion to that on the healthy side was 1.4 and more. The ratio of renin activity in plasma of blood in the renal veins is an important diagnostic and prognostic criterion.
