An AI stethoscope detected heart valve disease with 92% accuracy in adults over 50, outperforming traditional stethoscopes.
An AI-powered digital stethoscope detected moderate to severe valvular heart disease at 92.3% sensitivity—more than double traditional stethoscopes’ 46.2%—in a U.S. study of 357 adults aged 50 and older, according to research published in the European Heart Journal - Digital Health on February 5, 2026.
The tool, using machine learning to analyze heart sounds, showed promise in identifying a condition often missed due to subtle or absent symptoms, potentially enabling earlier treatment and reducing hospitalizations.
While slightly lowering specificity, researchers believe the benefits of earlier detection outweigh the risks, and emphasize that doctors remain essential in interpreting results.
