Brief summary
The aim of this randomized controlled trial is to compare the impact of a case manager-led smartphone-assisted hybrid cardiac rehabilitation program with usual care in patients with HF. Participants will undergo a 12-week program led by a case manager and assisted by a smartphone. The study aims to answer two main questions: 1. Is the novel cardiac rehabilitation model feasible for patients with HF? 2. Does the intervention group show a significant improvement in exercise capacity and adherence compared to the usual care group?
Interventions
OTHERsmartphone-assisted hybrid cardiac rehabilitation (SHCR)
The 12-week case manager-led SHCR program includes: * Customized exercise prescriptions following ACSM's heart failure guidelines. * A hybrid program combining in-person sessions, home self-exercise, and videoconferencing for exercise coaching(optional), supported by a smartphone app. * Case managers instruct patients on a communication app for weekly follow-ups, health education messages, exercise reminders, and progress tracking, including metrics like blood pressure, heart rate, weight, and symptoms.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of peak oxygen uptake | at baseline, 12 weeks(post-intervention), and 6 months. | Peak oxygen uptake will be assessed using cardiopulmonary exercise test before intervention, at 12 weeks (post-intervention), and at 6 months. |
| Change of 6 minute walking test | at baseline, 12 weeks(post-intervention), and 6 months. | 6 minute walking test will be performed before intervention, at 12 weeks (post-intervention), and at 6 months. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Depression | at baseline, 12 weeks(post-intervention), and 6 months. | The investigators will assess the change in Patient Health Questionnaire (PHQ-9). The PHQ-9 score ranges from 0-27. Higher scores indicate worsen symptoms. |
| Anxiety | at baseline, 12 weeks(post-intervention), and 6 months. | The investigators will assess the change in Generalized Anxiety Disorder scale (GAD-7). The GAD-7 score ranges 0-21. Higher scores indicate worsen symptoms. |
| Evaluation of physical activity | at baseline, 12 weeks(post-intervention), and 6 months. | The investigators will assess the change in physical activity using International Physical Activity Questionnaire(IPAQ) Taiwan version. |
| Evaluation of grip strength | at baseline, 12 weeks(post-intervention), and 6 months. | The grip strength will be measured using a grip goniometer with the participants seated and the elbow flexed at 90 degrees. |
| Evaluation of frailty | at baseline, 12 weeks(post-intervention), and 6 months. | The investigators will evaluate the change in the Clinical Frailty Scale, which ranges from 1 to 9. Higher scores represent greater illness. |
| Adherence to prescribed exercise | 12 weeks(post-intervention) | We will evaluate the percentage of completed prescribed exercises at 12 weeks. |
| Blood test: LDL | at baseline, 12 weeks(post-intervention), and 6 months. | The LDL will be tested in the laboratory. |
| Blood test: HDL | at baseline, 12 weeks(post-intervention), and 6 months. | The HDL will be tested in the laboratory. |
| Blood test: Triglyceride | at baseline, 12 weeks(post-intervention), and 6 months. | The Triglyceride will be tested in the laboratory. |
| Blood test: NT-proBNP | at baseline, 12 weeks(post-intervention), and 6 months. | The NT-proBNP will be tested in the laboratory. |
| Blood test: Total cholesterol | at baseline, 12 weeks(post-intervention), and 6 months. | The Total cholesterol will be tested in the laboratory. |
| Evaluation of Quality of life | at baseline, 12 weeks(post-intervention), and 6 months. | The investigators will assess the change in 36-Item Short Form Survey(SF-36). |
