title: [Study of hemodynamics in patients with acromegaly by means of radiocardiography].
abstract: Determination of the indices of central hemodynamics by means of radiocardiography shows them to be essentially changed in patients with acromegaly in the active stage. A clear correlative relationship has been established between the shifts in hemodynamics and the heart volume determined by X-ray. The diagnosis of preclinical stage of circulatory insufficiency is based on revealing a statistically significant increase in the stroke index and a decrease in the circulation volume and total peripheral resistance. In the early stage of acromegaly there is a statistically significant increase in the minute and stroke indices, in the index of minute work, and in the coefficient of circulation effectiveness. With an increase in the duration of the disease, these indices decrease considerably, which denotes hemodynamics deterioration.
