Your phone could soon hear a silent heart condition
NCT ID NCT06404437
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tests whether a smartphone app, using its built-in microphone and machine learning, can detect severe aortic stenosis – a common but serious heart valve issue. Researchers will record heart sounds from 100 adults (with and without the condition) and compare the app's accuracy to standard digital stethoscopes. If it works, this could make screening faster 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
smartphone app with machine learning
What this could lead to
If successful, this could lead to a quick, accessible screening tool for aortic stenosis using just a smartphone.
What could go wrong
This is a small pilot study (100 participants) testing algorithm accuracy, not a treatment. The app may not be reliable enough for real-world use yet.
