[Changes in vascular reactivity during the noradrenaline test in patients with hypertension]. / Izmeneniia sosudistoi reaktivnosti pri provedenii proby s noradrenalinom u bol'nykh gipertonicheskoi bolezn'iu.

To study vascular responses and to choose a differential therapy, 51 patients with hypertensive disease underwent a pressor test combined with intravenous epinephrine. The test revealed two types of blood pressure control. In type I responses (normotensive responses), there was a good antihypertensive effect shown by beta-adrenoblockers and/or a course of physical trainings. In type II (hypertensive responses), alpha-adrenoblockers and diuretics proved to be more effective. A relationship was found between the type of responses and the activity of the renin-aldosterone system.
