[The renin-angiotensin-aldosterone system in hypertensive subjects. III- The use of beta-blockers in reno-vascular hypertension (author's transl)].
Six patients with permanent hypertension with renal artery stenosis were treated by conservative reparative surgery appart from one of them (unilateral nephrectomy) and were all seen again at the 8th month at the earliest in the absence of any anti-hypertensive therapy. Study of the renin-angiotensin system carried out on a normal sodium diet, after stopping all anti-hypertensive treatment for at least 15 days, was combined with the anti-hypertensive response under the influence of a beta-blocker. There were two types of response pre-operatively: firstly, with beta-blockers alone a normal blood pressure which remained normal postoperatively; the second group of patients remained hypertensive, requiring the addition of diuretics, and remained hypertensive after surgery. This response, although non-specific, would appear to represent an important element in assessing the curability of reno-vascular hypertension.
