CADScor®System: How Does it Work?
An AI-powered acoustic diagnostic aid to rule out significant coronary artery disease in 10 minutes.*
Rule-Out Significant CAD in 10 Minutes with at least 96% Confidence (Negative Predictive Value)²
CADScor®System is based on ultrasensitive phonocardiography, which refers to an audio recording of the sounds made by the heart (heart sounds). Coronary artery disease (CAD) causes alterations to heart sounds. This novel technology listens to these sounds, some of which are not audible to the human ear.
When a patient with CAD develops an obstructive stenosis(es), coronary blood flow is interrupted, which creates turbulence or a small murmur.³ In addition, how the heart relaxes in between beats in the presence of CAD can also change features of the heart's sounds.⁴ An integrated scoring algorithm developed in collaboration with Aalborg University evaluates the heart sounds, and the computer-based algorithm rules out suspected CAD in patients.¹ The integrated, easy-to-use touch screen displays the individual CAD-score, indicating patients' low or elevated CAD risk.
An AI-Powered Acoustic Assessment Drives the CAD-Score to Indicate Low or Elevated Significant CAD Risk in Patients¹
Elevated Risk
Significant CAD cannot be ruled out. Refer for further diagnostics.
