Can your smartwatch spot heart failure clues?
NCT ID NCT04998877
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how data from wearable devices (like activity trackers and heart monitors) relates to heart and muscle function in people with a type of heart failure called HFpEF. Researchers will compare 60 adults with and without HFpEF using tests like MRI, exercise testing, and blood work. No treatment is given—the goal is to learn how wearables might help monitor the condition.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this study could help doctors use wearable devices to better monitor and manage heart failure with preserved ejection fraction (HFpEF).
What could go wrong
This is an observational study, not a treatment trial. It will not directly improve health, and results may not apply to all patients with HFpEF.
