Objective: The objective is to assess the influence of cardiac rehabilitation (CR), represented by self-controlled walking in middleaged men with different onsets of coronary heart disease (CHD), on the muscular strength of the hand flexors, muscle mass and 6-minute walking distance. Methods: 90 men aged from 45 to 65 with the same prescriptive CHD with different onsets: myocardial infarction (MI) – 56 patients, or stable angina – 34 patients were examined. After 9 months of CR we have assessed the muscular strength of the hand flexors (MSHF), have run the bioelectrical impedance analysis and 6-minute walking test, have determined the level of testosterone in blood serum. Results: In patients with CHD with MI as an onset, MSHF of the right hand increased from 43 to 49 DAN at the average, and from 41 to 46 DAN – of the left hand; equity proportion of muscle tissue increased from 48.4 to 48.8% , 6-minute walking distance – from 450 to 500 meters. In patients with CHD with stable angina as an onset, the proportion of muscle tissue decreased from 48.2 to 47.3 %, 6-minute walking distance – from 405 to 400 meters without significant improvement of MSHF. Conclusions: 9-month CR in patients after MI had a positive effect on MSHF, muscle tissue and stamina as opposed to the patients with stable angina.
