Using Apple Watch data to predict heart failure outcomes

Official title: Predicting Heart Failure Recovery by Wearables and Machine Learning

Run by University Medical Center Goettingen · NCT06819618 · Data updated 2026-11-12

This study is testing if data from Apple Watches can help predict heart failure problems and the chances of needing to go back to the hospital for patients with heart failure.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults over 17 years old with heart failure with reduced ejection fraction who have been hospitalized for decompensated heart failure.

Probably not a fit

Patients with a life expectancy of less than 6 months due to non-cardiac conditions or those unable to use a smartwatch may not benefit from this study.

What this trial studies

This observational study aims to determine how effectively data collected from Apple Watch can predict the heart failure status of patients experiencing decompensation. By extracting physiological data such as ECG readings, SpO2 levels, respiratory rates, and step counts, the study will utilize machine learning techniques to forecast risks of decompensation and rehospitalization. The research builds on previous findings that highlight the correlation between wearable device metrics and clinical outcomes in heart failure patients, advancing the use of multimodal data for risk assessment.

Why it matters

Potential benefit: If successful, this study could enhance early detection and management of heart failure, potentially reducing hospitalizations and improving patient outcomes.

How similar studies have gone: Previous studies have shown promise in using wearable devices for cardiovascular assessments, indicating that this approach may yield valuable insights, although the specific combination of methods in this study is relatively novel.
