This study aimed to investigate the impact of Chan-Chuang Qigong on fatigue, exercise capacity, quality of life, and heart function in heart failure patients. The study recruited 72 heart failure patients from a medical center in northern Taiwan for an experimental study. The participants were randomly divided into two groups: patients in experimental group was given twice daily, every 15 minutes Chan-Chuang qigong, control group received the regular care for heart failure patients. Data was collected using the Piper Fatigue Scale, a six-minute walking test, and the Minnesota Living with Heart Failure Questionnaire before the intervention as the baseline, and at the 4th, 8th, and 12th weeks during the intervention. It is hoped that through this study, we can understand the effect of Chan-Chuang qigong on improving fatigue, exercise capacity and quality of life in patients with heart failure, and provide an additional choice and reference for the treatment and care of patients with heart failure in the future, and recommend future treatment of heart failure.
