[Importance of a comprehensive instrumental assessment of cardiovascular system function for the expert medical work evaluation of ischemic heart disease patients].
A total of 103 patients with ischaemic heart disease (IHD) were investigated 1 1/2 to 10 years after myocardial infarction. The functional state of the cardiovascular system was studied with the aid of electrocardiography, tetrapolar chest rheography and spiroergometry in the bicycle ergometric test. This test revealed ischaemic shifts on the ECG in 63% of patients with IHD. Patients with IHD, as compared to the control group of normal individuals, showed lowered tolerance to exercise and shifts in the indices of the central haemodynamics and gaseous exchange, including less manifest increase of the stroke and minute volume of blood, and oxygen consumption. The results of the study permitted the authors to diagnose the initial state of the cardiac insufficiency and to graduate the functional possibilities of the cardiovascular system in patients with IHD. It is recommended to use such a comprehensive cardiological study of the functional state of the cardiovascular system for medical assessment of the working capacity of IHD patients.
