Key result
A 12-week nurse-led mHealth intervention improves daily steps, functional capacity, and LVEF versus usual care.
Why the study?
Does a 12-week nurse-led home-based mHealth cardiac rehabilitation program improve physical activity and cardiopulmonary function in patients with chronic heart failure?

Does a 12-week nurse-led home-based mHealth cardiac rehabilitation program improve physical activity and cardiopulmonary function in patients with chronic heart failure?
A 12-week nurse-led mHealth cardiac rehabilitation program integrating wearable tracking and behavioral coaching significantly improves physical activity and cardiopulmonary function in patients with chronic heart failure.
Supports nurse-led mHealth coaching in chronic HF care; extends self-care theory to wearable-integrated interventions.
This 12-week randomized controlled trial evaluated a nurse-led mHealth intervention for patients with chronic heart failure, conceptually informed by Riegel’s middle-range theory of self-care of chronic illness. The program integrated wearable activity tracking with weekly nurse-led behavioral coaching, reflecting the core self-care processes of monitoring, maintenance, and management. Compared with usual care, the intervention significantly improved daily step count, 6-minute walk distance, metabolic equivalents, and left ventricular ejection fraction. Findings highlight the effectiveness of theory-informed, nurse-delivered mHealth strategies in enhancing physical activity and cardiopulmonary function, while underscoring the critical role of advanced practice nurses in home-based chronic disease management.

Chang et al. (2026) conducted an RCT in chronic heart failure. Nurse-led mHealth intervention vs. usual care was evaluated on daily step count, 6-minute walk distance, metabolic equivalents, and left ventricular ejection fraction. A 12-week nurse-led mHealth intervention significantly improved daily step count, 6-minute walk distance, metabolic equivalents, and left ventricular ejection fraction compared with usual care.
