| Description | Aim: The aim of this study is to assess an impact of aerobic-resistance exercise on cardiorespiratory indicators in patients after aortic valve replacement (AVR), and evaluate monitored parameters as a result of a positive influence of a physical activity level. Methods: The study was conducted between years 2005-2015 on a group of 65 patients of an average age of 60,5±10 years, with left ventricular ejection fraction of 56,5±6 percent. All patients were after AVR. All these patients were included in a cardiac rehabilitation training program (CR). CR included a three-month aerobic-resistance training with a frequency of three times a week. The length of a training unit was set to 80 minutes (out of which 50 minutes were allocated to individual aerobic training). The control group consisted of 20 patients after AVR who did not exercise systematically (but they exercised on an individual basis, supervised by their attending cardiologist). Both groups were assessed by exercise echocardiography and spiroergometry as well as clinically, before and after CR. Results: Completing the interventional training program led to a significant increase of exercise tolerance (1,5±0,3 vs. 1,8±0,3 W/kg; p<0.0001) and of peak oxygen consumption (19,2±0,9 vs. 23,5±1 ml/kg/min., p<0.0001). Decreased values of resting heart rate and resting systolic and diastolic blood pressures were observed in subjects after completing CR. However, the measured changes did not reach a statistical significance. In the control group, the improvement in functional and aerobic capacity also occurred but did not achieve statistical significance. Conclusion: The study showed some important connections that can be utilized for practical application of aerobicresistance training prescription for patients after AVR. Significant improvement in cardiorespiratory indicators and indicators of exercise tolerance after completing CR reinforces the crucial role of physical activity. Cardiac rehabilitation training program after AVR allows an exact evaluation of the outcome of the surgery and also an adjustment of pharmacologic therapy, particularly the anticoagulant therapy. The influence of regular exercise on longterm prognosis is not yet clear and will require long-term trials in larger numbers of patients. Outpatient rehabilitation after AVR correction is a safe treatment method. |
