New tech trial aims to get heart failure patients moving
NCT ID NCT07171372
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests a personalized system that uses a mobile app and smart wristband to encourage physical activity in 82 adults with heart failure. Participants get custom activity goals, real-time feedback, and motivational support over 12 months. The goal is to see if this approach can improve exercise adherence and reduce sedentary behavior.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- IoT-based physical activity monitoring system (mobile app and smart wristband)
- What this could lead to
- If successful, this system could help heart failure patients become more active and improve their daily functioning and quality of life.
- What could go wrong
- This is a small, early-stage trial with 82 participants, so results may not apply to all heart failure patients. The intervention relies on technology and motivation, which may not work for everyone.
