As an important component of Chinese Qigong exercises, Baduanjin exercise has origins in ancient martial arts that have been practiced for thousands of years. It is a combination of moderate-intensity physical activity, meditation, and body awareness, which designed to improve holistic health. Baduanjin exercise can systematically exert the movable joints and muscle, enhance cardiopulmonary functions, and concurrently modulate mind and spirit, ultimately achieve the integration of mind and body. Many clinical studies have demonstrated the beneficial effects of Baduanjin exercise on decreasing cholesterol and triglyceride concentrations, controlling systemic hypertension, stabilizing glucose and glycosylated hemoglobin levels. Some review articles have described Baduanjin exercise as a therapy with potential to exert positive impacts on cardiopulmonary function. Additionally, several recent studies have proven the benefits of Baduanjin exercise including preventing ischemic stroke, relieving pain and stiffness, and improving sleep quality and psychological well-being. However, it is not known if Baduanjin exercise could be a feasible approach for post-MI individuals because the scientific basis for this intervention is limited. To address a research gap, the BE-PREMIER (Baduanjin Exercise PREvents post-Myocardial Infarction left vEntricular Remodeling) trial is designed and to assess LV remodeling in clinically stable post-MI patients after a 12-week period of Baduanjin exercise-based cardiac rehabilitation.
