Порог вкусовой чувствительности к поваренной соли и эффективность лечения впервые выявленной артериальной гипертензии

Gustatory sensitivity threshold to table salt (GST) and extracellular fluid volume (EFV) were determined in 128 patients with arterial hypertension (mean age 54.1+-0.5 yr; 79 men) before and 3 month after antihypertensive therapy. Those with the initially high GST (sensing salt in its 0.32% solution) had AP 161+-2/97+-1 mm Hg, myocardial mass 235.1+-13.2 g and left ventricular diastolic size 4.91+-0.07 compared with 151+-1/93+-1, 203.5+-7.8 and 4.71+-0.05 respectively in patients with low GST. The treatment resulted in a decrease of AP and EFV by 14-19 and 12% respectively in all the patients. In those with high GST it decreased after intake of indapamide by 49% vs 24 % in the absence of therapy. In patients with initially low GST, it decreased (by 37%) only after intake of diuretics. It is concluded that changes of GST reflect activation of mechanisms leading to a stable drop of AP.
