[The effect of radon baths at the Khmel'nik health resort on the central hemodynamic indices and calcium-regulating hormones in patients with essential hypertension].

A total of 132 patients with stage I, II, essential hypertension were examined. Indices for central hemodynamics were determined as were the levels of parathormone, calcitonin, and ionized calcium. Radon baths in eukinetic and hypokinetic types of circulation caused a significant reduction in mean hemodynamic pressure and resulted in improvement of patency of arterioles. In so far as hyperkinetic type of hemodynamics is concerned, there was a significant reduction in cardiac index and an increase in specific peripheral resistance. The level of ionized calcium got increased in all the patients, the same being true of the levels of parathormone and calcitonin in cases of eukinetic and hyperkinetic types of circulation.
