Gene Expression Testing for Coronary Artery Disease

Does Not Apply to Commercial Genetic Testing Program effective 6/1/2018

DESCRIPTION

Obstructive coronary artery disease (CAD) in individuals with stable chest pain is typically evaluated by stress echocardiography, myocardial perfusion imaging, and computed tomography angiography. Corus CAD™, developed by CardioDX®, Inc., is a genomic test designed for use in an outpatient setting with clinically stable, non-diabetic individuals who present with chest pain or who have a high risk of coronary artery disease but do not have a previously diagnosed myocardial infarction or prior revascularization procedure. Test results are provided as a numeric score that quantifies the likelihood that the individual with stable chest pain has obstructive CAD.
