Effectiveness of a Home-base Walking Exercise Program on Depression,Frailty,and Quality of Life in Patients With Heart Failure: A Single-Center Randomized-Controlled Trial

Heart disease is the second leading cause of death in Taiwan, with approximately 700,000 individuals affected by heart failure. Despite the proven benefits of rehabilitative exercise, participation in cardiac rehabilitation remains suboptimal. To address this, integrating physical activity into daily life, such as home-based walking exercises, offers a practical alternative to promote health and improve outcomes in heart failure patients. Walking exercises have been shown to significantly impact mortality rates and enhance the quality of life in this population. This study aims to assess the effects of a 12-week home-based walking exercise program on depression, frailty, and quality of life in patients with heart failure. Using an experimental design, heart failure patients hospitalized in a medical center's internal medicine ward were randomly divided into an experimental group (n=34) and a control group (n=34). While both groups received standard health education, the experimental group also participated in a home-based walking intervention after discharge. Data were collected before the intervention and at the 1st and 3rd months post-intervention. The generalized estimation equation (GEE) was employed to analyze changes in depression, frailty, and quality of life, focusing on group differences and interactions between time and group. The expected outcomes of the study include improved quality of life, reduced frailty, and alleviated depression in the experimental group, highlighting the value of home-based walking exercise. Additionally, the intervention model can complement existing post-discharge nursing practices by incorporating remote nursing guidance to enhance exercise adherence without increasing healthcare costs. This approach not only benefits patients by encouraging long-term physical activity but also reduces the burden on healthcare systems, making it a sustainable and effective strategy for managing heart failure.
