Patients after cardiac infarct and primary PCI are mainly people shortly immobilized with slight damage of the heart muscle with good condition and low consciousness of the disease. Development of the cardiology gives new goals for a cardiac rehabilitation. Traditional rehabilitation targets just like preventation results of immobilization and raising of efficiency are now not so important. Main task of modern rehabilitation, except function improvement of life quality, is preventation of progress coronary disease and reduction of mortality by changing health behavior, especially consent to regular physical activity. The purpose of this study was to evaluate physical efficiency and life quality of life in patients after myocardial infarction treated with PCI who participated in residential cardiac rehabilitations according to age and time of beginning this process. 167 patients (male) after myocardial infarction treated with primary PCI in age 33-82 years, mean age 57,1 +/- 8,92 (years). All patients participated in a 20 +/- 2 (days) comprehensive residential cardiac rehabilitation. ECG treadmill exercise test according Bruce protocol was performed after beginning and at the end of rehabilitation process. Quality of life was evaluated according to SF-36 questionnaire completed at the beginning and after rehabilitation programm. Residential cardiac rehabilitation increases physical efficiency and improves quality of life in patients who undergo primary PCI after myocardial infarction. Effects of cardiac rehabilitation dose not depend on age or on time of beginning of rehabilitation. Most significant increase of physical efficiency was observed in patients who were referend to cardiac rehabilitation no longer then 6 weeks after cardiac event.
