Summary

This study is testing whether a simple, non-invasive sensor called photoplethysmography (PPG) — already found in many smartwatches — can accurately predict how well the heart pumps blood (ejection fraction) and other heart health measures. Researchers will have 500 adults wear a PPG device during an echocardiogram and use artificial intelligence to see if the sensor's signals can replace or supplement the ultrasound test. If it works, it could make heart monitoring easier and more accessible.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Photoplethysmography (PPG) sensor
What this could lead to: If successful, this could allow people to monitor key heart metrics like ejection fraction and blood pressure using a simple wearable device, without needing an echocardiogram.
What could go wrong: This is an early-stage observational study with 500 participants, so the results may not apply to everyone. The PPG predictions are based on AI models that may not be accurate enough for clinical use.
