[Functional status of the cardiovascular system in Hodgkin's disease and the effect of radiotherapy].

The main indices of cardiohemodynamics, phase structure of the cardiac cycle and ECG were studied in 34 patients with Hodgkin's disease aged 16 to 43: before the initiation of therapy, after a course of radiotherapy and in long term after therapy. The patients were characterized by tachycardia increasing with a degree of a process, ECG signs of myocardiodystrophy, a tendency to the formation of the phase syndrome of hypodynamia, slight pulmonary hypertension, a decrease in AP and peripheral vascular resistance. After a course of radiotherapy according to a radical program functional indices of the cardiovascular system in most of the patients returned to normal. However signs of radiation pericarditis with a favorable clinical course developed in some patients. Long after therapy positive changes in the cardiovascular system were noted among patients with IIA stage, negative shifts were noted in patients with III-IV stage.
