ABSTRACT
Exercise tolerance, determined in the early stages of cardiac rehabilitation during exercise tests upon discharge from the hospital, is an important functional indicator of the cardiovascular system in patients with coronary heart disease after revascularization operations. Exercise tolerance should be taken into account when planning and evaluating the effectiveness of rehabilitation measures at all stages of treatment. 126 elderly patients with acute coronary syndrome were examined. Emergency angioplasty and coronary artery stenting were performed. Examination, treatment, and inpatient rehabilitation were performed in accordance with clinical guidelines, protocols, and standards for the treatment of patients with acute myocardial infarction. Before patients were discharged from the hospital, transferred to an inpatient rehabilitation department, or a specialized sanatorium, stress tests were performed on patients (the symptom was a limited bicycle ergometry and a six-minute walking test). According to the results of early exercise tests, patients are stratified by the level of exercise tolerance. To identify clinical predictors that affect the results of exercise tests and, consequently, the level of exercise tolerance in general, a step-by-step discriminant analysis was performed, which allowed us to identify significant factors that determine the formation of exercise tolerance. The influence of such predictors as body mass index, troponin level determined 24 hours after endovascular myocardial revascularization, systolic function of the left ventricle on exercise tolerance in patients with coronary heart disease after endovascular myocardial revascularization was determined. Exercise tolerance predictors are the basis for building personalized cardiac rehabilitation and developing safe and effective physical rehabilitation programs at all stages of medical care after revascularization surgery.
