[Multifactorial analysis of the physical work capacity of patients with chronic ischemic heart disease]

A series of 512 patients with coronary heart disease were examined using a complex of clinical, instrumental and biochemical methods. The capacity for physical work was determined by bicycle ergometry. Fifty-four signs were studied in relation to the exercise tolerance. On the basis of the findings about the closeness of the correlation between these signs and the patients' capacity for physical work, 19 prognostically significant criteria were identified. A multi-factorial clinico-functional and biochemical classification of coronary heart disease patients with regard to three levels of the capacity for physical work was elaborated which made it possible to develop a method of the complex assessment and prediction of the capacity for physical work.
