title: [The interrelation of the sodium-excretory function of the kidneys and vascular reactivity in hypertension patients].
abstract: Vascular reactivity was evaluated by a modified photoplethysmographic method in 20 patients with essential hypertension before and after an acute volumetric salt load. A relationship was demonstrated between vascular reactivity and renal sodium excretion pattern under stress. Patients with "excessive" natriuresis 24 h after the test showed reduced vascular reactivity, and slow sodium and water excretion was associated with increased vascular response. A study of membrane Ca2+ transport 24 h after the test showed an increase in receptor-dependent Ca2+ uptake in response to all inductors (platelet aggregation factor, vasopressin, ADP), as compared to the baseline.
