    Abstract:
    The aim of the study was to compare initial clinical, hemodynamic, and vegetative parameters in patients with myocardial infarction (MI) who had undergone physical rehabilitation with different results. The subjects were 106 male patients aged 48.6 +/- 0.95 years undergoing sanatorium rehabilitation after MI. According to the dynamics of exercise tolerance (ET) during the course of treatment, the subjects were divided into three groups: group one consisted of 39 patients with a significant ET growth of more than 10W, group two consisted of 47 patients with no changes in ET or its insignificant growth of less than 10W, and group three consisted of 20 patients with a decrease in ET revealed during a repeated test. In group three patients, the initial EchoCG examination revealed a higher degree of myocardial lesion, which was manifested by lowered ejection fraction and sphericity index, increased end-diastolic volume, and increased degree of left ventricular (LV) asynergy. Furthermore, day-time ventricular extrasystoles were more frequent in these patients; the number of patients with large-focal MI, LV aneurysm, and post-infarction stenocardia was also higher in group three. Correlation and multiple step regression analysis revealed that both initial parameters of vegetative nervous system, data from initial load test, and the EchoCG measurements of the right atrium were associated with the degree of ET growth according to VEM results. The data from the study are able to help individualize rehabilitation of MI patients, especially those with severe myocardial lesion.
