Coronary Artery Disease

What is Coronary Artery Disease?

Heart disease is the leading cause of death in the United States and coronary artery disease (CAD) is the most common cardiovascular disease.¹ CAD is caused by plaque buildup in the wall of the arteries that supply blood to the heart. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis, which can lead to a heart attack if left untreated.

The primary symptom of CAD is chest pain, often associated with breathing difficulties, dizziness, or nausea. It is often difficult to determine whether chest pain is related to the heart or not.²

Diagnosing Coronary Artery Disease

Approximately 20-40% of the population will experience chest pain during their lifetime.3,4 Chest pain symptoms are one the most common reasons for seeking medical attention.9,10 It is often difficult to determine whether chest pain is related to the heart or not, and many patients undergo multiple diagnostic assessments.11 However, 9 out of 10 patients do not suffer from significant CAD.5,6,7 It is important to both patients and healthcare systems to be able to reduce unnecessary patient examinations and significant cost burden.

CADScor®System offers an entirely new approach to early assessment and rule-out. Physicians now have an easy-to-use, rapid diagnostic aid for patients with stable chest pain and suspected CAD.

CADScor®System

CADScor®System is a point-of-care diagnostic aid that uses highly sensitive acoustics and advanced computational processing to analyze the patient’s coronary blood flow. The system calculates a patient-specific CAD-score, and couples it with risk factors to rapidly indicate the patient’s risk of significant coronary stenosis for immediate risk stratification, prior to potential secondary evaluation.12 CADScor®System has been used in over 40,000 patient assessments8 and has CE-marking and FDA De Novo clearance.

CADScor®System Research, Development and Clinical Studies

CADScor®System is approved in Europe with CE-marking and has received FDA De Novo clearance as a diagnostic aid for symptomatic patients with suspected CAD. Multiple clinical studies have been published to demonstrate CADScor®System’s performance.
