About Corus CAD
Corus CAD is a clinically validated genomic test that integrates gene expression levels and other patient characteristics to assess the likelihood of obstructive CAD. The test is intended to be used in an outpatient setting with clinically stable, non-diabetic patients who present with chest pain or who have a high risk of coronary artery disease, but without previously diagnosed myocardial infarction (heart attack) or prior revascularization procedure. Corus CAD is convenient and safe, and only requires a standard blood draw procedure. The test yields an objective result delivered to the physician in the form of a numeric score that quantifies the likelihood that a patient with stable chest pain has obstructive CAD.
CardioDx designed a prospective, nationwide, multi-center clinical study, PREDICT (Personalized Risk Evaluation and Diagnosis in the Coronary Tree, www.clinicaltrials.gov) to develop and validate Corus CAD. The PREDICT study sought to determine whether a gene expression test could be developed to identify obstructive CAD in patients with stable chest pain. The company has collected more than 2,800 patient samples in PREDICT from more than 40 clinical sites in the United States as of April 2009. Trial results and the Corus CAD validation data will be presented at a major scientific meeting later in 2009.
About Obstructive CAD
Cardiovascular disease affects tens of millions of Americans each year and is the leading cause of death in the United States. Coronary artery disease (CAD) is a narrowing or blockage of the coronary arteries (the major blood vessels that supply the heart with blood, oxygen and nutrients) that reduces blood flow to the heart muscle. As a result of the blockage, the heart does not get enough oxygenated blood, which can often cause chest pain (angina), shortness of breath and other symptoms. A severe blockage can cause a hear
