[Studies on central and peripheral hemodynamics using radiocardiography and Xenon-133 muscle clearance in patients with essential hypertension].
Examination of 80 patients with essential hypertension revealed a significant correlation between the tonus of peripheral muscular arterioles on the one hand, and the stage and duration of hypertension and age of the patients, on the other hand. The correlation between arteriolar tonus and indicators of cardiac pump function was less marked. The results confirmed the close relationship between changes of peripheral blood bed and development of hypertension. The use of 133Xe half-period for measuring the peripheral arteriolar tonus proved a simple, but informative method adding an important indicator of peripheral haemodynamics to the results of haemodynamic examination.
