[Radionuclide evaluation of the cardiovascular system in arterial hypertension].
Proceeding from a study of the nature of changes in hemodynamics during development of hypertensive disease (HD) at its different stages it was shown that hemodynamic changes in 42.1% of the patients with Stage I-IIA HD were of hypertensive type, in the patients with Stage IIB-III HD normal and hypokinetic types of the blood circulation prevailed. After bicycle ergometry exercise the reactivity of the cardiovascular system was revealed more completely. The transition of one hemodynamic type into another and its detection acquired a great importance. The definition of the types of hemodynamics at rest and of effort was very important in terms of adequate antihypertensive therapy and the prediction of a subsequent course of disease. The most complete information on function of the cardiovascular system and myocardial contractility can be obtained with the help of radio-angiocardiography and radionuclide ventriculography. However in the absence of a gamma-chamber radiocardiography can provide necessary information on function of the cardiovascular system in case it is used in one and the same patient over time using bicycle ergometry testing.
