Evaluation of the CardioSond Electronic Stethoscope in the Detection of Coronary Artery Disease

Stopped early

Conditions studied: Coronary Artery Disease

In brief

The study is designed to evaluate the predictive accuracy of the CardioSond digital electronic stethoscope in the detection of coronary artery disease (CAD) in patients with and without known disease who are referred to cardiac computed tomography angiography (CT scans).

Who can join

Age: 20 and older, up to 80. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Willingness to sign an informed consent.

You may not qualify if…

• Inability to provide informed consent
• History of prior myocardial infarction, percutaneous coronary intervention (i.e. stents) or coronary artery bypass graft surgery
• Heart rate over 70 beats per minute post beta blockade
• Artery calcification resulting in non-diagnostic CT angiographic images
• Supraventricular or ventricular arrhythmias that would be expected to affect CT angiography image quality (e.g. atrial fibrillation, atrial flutter, ventricular tachycardia, bigeminy and trigeminy). Patients with isolated premature atrial contraction and premature ventricular contractions may enroll
• Any pulmonary condition that would create abnormal physical findings that would interfere with the fidelity of the cardiac sound recordings (e.g. obstructive pulmonary disease, such as asthma or COPD, with audible wheezing)
• Presence of audible aortic or pulmonic diastolic murmurs, tricuspid or mitral flow diastolic murmurs or continuous murmurs
• Any chest wall configuration preventing adequate contact between the CardioSond acoustic recording sensor and precordium
• Any medical condition that would be expected to affect CT angiography image quality
