Understanding Coronary Artery Disease
Coronary artery disease (CAD) is a very common heart condition in the United States. One in five deaths among Americans is caused by CAD.1
CAD can cause a narrowing or blockage of the coronary arteries (vessels to the heart that supply the heart with blood, oxygen, and nutrients), reducing blood flow to the heart muscle. This narrowing or blockage in the coronary arteries is often referred to as obstructive CAD.
As a result of the blockage, you can experience symptoms of chest tightness, pressure, or pain. Severe narrowing or complete blockage of the coronary vessels can lead to a heart attack or even death.
If you have chest discomfort or symptoms suggestive of CAD, it is important to see your healthcare provider so that he or she can determine whether you have a serious blockage in your coronary arteries.
Corus® CAD is a convenient blood test that allows your healthcare provider to safely assess whether or not you have a blockage in your heart. Only your healthcare provider can order the Corus CAD test. Ask your healthcare provider if Corus CAD may be right for you.
