title: [Comparative study of the exercise tolerance of patients with autonomic circulatory dystonia, angina pectoris and previous myocardial infarction].
abstract: Ninety-eight men were examined. Of these, 13 were practically healthy, 29 had vegetovascular dystonia, 15 stable angina pectoris, and 41 men suffered myocardial infarction. Each group was appraised for work fitness. The double product, work, chrono- and inotropic reserves of the heart, as well as the index of energy losses of the heart per unit of work were calculated. A significant decrease in chrono- and inotropic reserves of the heart were revealed in patients with demonstrable coronary pathology and with cicatricial lesions after myocardial infarction. The patients with vegetovascular dystonia showed inadequate response to the exercise, manifested by greater energy losses of the heart per unit of work as compared to normal.
