The effects of Guozhuang dance on exercise self-efficacy in coronary heart disease patients following percutaneous coronary intervention: a randomized controlled trial

Background: Coronary heart disease (CHD) is a leading cause of death. Despite PCI improving coronary perfusion, many patients face low physical activity, reduced self-efficacy, and poor quality of life, emphasizing the need for better rehabilitation. Objectives: To evaluate the effects of a 12-week Guozhuang dance intervention on exercise self-efficacy, functional capacity, physical activity, and health-related quality of life in CHD patients following PCI. Methods: = 44). Both groups received standard care; the control group participated in conventional rehabilitation, while the intervention group added Guozhuang dance. Outcomes measures were assessed at baseline(T0), at 4(T1) and 12(T2) weeks of intervention, and at 6 weeks after post-intervention (T3) using the Multidimensional Self-Efficacy for Exercise Scale (MSES), Six-Minute walk distance (6MWD), International Physical Activity Questionnaire (IPAQ), and the Chinese Questionnaire of Quality of Life (CQQC). Data were analyzed using intention-to-treat (ITT) analysis. The protocol was registered in the Chinese Clinical Trial Registry (ChiCTR2300069341). Results: = 0.065 > 0.05). Conclusion: A 12-week Guozhuang dance program significantly enhances exercise self-efficacy, functional capacity, physical activity, and quality of life in CHD patients after PCI, making it a valuable addition to traditional cardiac rehabilitation.
