Effects Of Rehabilitation Training On Exercise Tolerance Of Patients With Coronary Heart Disease After Percutaneous Coronary Intervention
Chinese Journal of Physical Medicine and Rehabilitation(2010)
Abstract
Objective To study the effects of rehabilitation training on the exercise tolerance of patients with coronary heart disease after percutaneous coronary intervention. Methods Fifty-sever cases of coronary heart disease after percutaneous coronary intervention were given routine medical treatment and divided randomly into a rehabilitation training group (26 cases) and a control group (31 cases). Patients in the rehabilitation training group started staged rehabilitation training of increasing intensity 3 days after percutaneous coronary intervention, and continued for a period of 3 months. Their heart rate, blood pressure, changes in ECG during treadmill exercise, as well as the frequency of any angina episodes were observed. Results The results showed that rehabilitation training could not only prolong the patients' total exercise time, the latency of ST segment depression and the incidence of exercise-induced angina, but also improve their exercise tolerance ( P < 0. 05 , or 0.01). However, the heart rate and blood pressure before and after exercise were similar in both groups. Conclusion Rehabilitation training could significantly relieve angina, improve ischemia's ECG manifestations and increase the exercise tolerance of patients with coronary heart disease after percutaneous coronary intervention.
