Cost-effectiveness and Safety of the CADScorSystem in Patients With Symptoms Suggestive of Stable Coronary Artery Disease.

The CADScor®System is a low cost, low resource-demanding, non-invasive, radiation-free device using highly advanced analysis of sounds originating from blood flow turbulence in the coronary circulation and myocardial motion. Heart sound recordings are obtained transcutaneously during a 3 minutes recording period with a microphone mounted at the IC4. A CAD-score on a scale from 0 to 99 is estimated immediately after the recording with a fully automated algorithm. The algorithm measures eight acoustic properties and the resulting acoustic score is combined with the clinical risk factors gender, age, and hypertension. The entire procedure lasts approximately 10 minutes.
