Objective. is study aims to identify whether Qigong (QG) rehabilitation therapy can significantly improve the cardiac function of patients with stable coronary artery disease (SCAD) compared with routine therapy. us, a randomized controlled trial was conducted to evaluate the curative effects of a three-month QG rehabilitation therapy on cardiac rehabilitation. Patients and Methods. In this trial, a total of 68 patients with SCAD were randomly divided into the QG group (34 patients) and the control (CON) group (34 patients). Patients in the CON group received routine cardiologic medication without any special intervention. Based on the treatment in the CON group, patients in the QG group were provided additionally with a 12-week traditional Chinese medicine (TCM) cardiac rehabilitation QG exercise training program. e outcomes of these patients were assessed at baseline and after 12 weeks of intervention through the treadmill (anaerobic threshold (AT)) test. Results. After 12 weeks of intervention, the AT, volume of oxygen (VO2), oxygen uptake/kilogram (VO2/kg), metabolic equivalents (METS), and oxygen pulse (VO2/HR) of patients in the QG group were significantly higher than those of patients in the CON group (P < 0.05). Conclusion. QG therapy can achieve certain curative effects and safety for patients with SCAD. is trial is registered with Clinicaltrials.gov identifier (ChiCTR1800015823). 1. Introduction Exercise training intervention can reduce the overall mor- tality of patients with heart diseases. Monitored exercise training is also an important component of a comprehensive cardiac rehabilitation plan [1, 2]. e potential car- dioprotective effect of regular sports has been confirmed by clinical evidence, which shows that long-term regular aer- obic endurance training can increase the risk factors of cardiovascular diseases [3]. e QG therapy training is similar to the aerobic training, but it has some distinct characteristics. For instance, it can regulate the body, breathing, and psychology of individuals who conduct this training program [4]. QG exercise prescription refers to that rehabilitation where doctors or physiotherapists prescribe the type, intensity, time, and frequency of QG exercise in the form of prescription, put forward matters needing attention in the QG exercise, and make patients achieve rehabilitation through regular training. However, there is not enough evidence to support the effectiveness and safety of QG therapy in cardiac rehabilitation. e anaerobic threshold (AT) refers to the level of ox- ygen uptake during exercise in a cardiopulmonary exercise test. Beyond this level, anaerobic metabolism will supple- ment aerobic metabolism to produce energy. e higher the AT is, the stronger the aerobic function is. According to previous studies, moderate-intensity aerobic exercise training can improve the AT of patients with heart diseases, which provides a strong basis for the formulation of clinical cardiac rehabilitation exercise treatment plans [5].
