Your symptoms may indicate a blockage in your heart—or they may not. Now, a simple blood test can help your doctor know.

As a woman, you may experience more varied and less obvious symptoms of obstructive coronary artery disease (CAD)* compared to men.1 These atypical symptoms can occur with or without typical symptoms such as chest discomfort and shortness of breath and may include:

  • Tightness or pressure in the throat, jaw, shoulder, abdomen, back, or arm
  • Squeezing, heaviness, or burning sensation in the upper body
  • Abdominal discomfort or fullness
  • Indigestion or heartburn
  • Onset of generalized weakness
  • Nausea
  • Vomiting
  • Dizziness or light-headedness
  • Palpitations or awareness of heartbeat

If you are experiencing symptoms suggestive of obstructive CAD, there are several diagnostic tests available. However, traditional cardiac stress tests, such as an EKG treadmill test, myocardial perfusion imaging (MPI), and stress echocardiography, don’t account for the cardiovascular differences between men and women, which is one of the reasons your doctor may want to use a test that does.2-5,†

The Corus CAD Test: A Safe and Effective Option for Women

Corus CAD is the only sex-specific test designed to help your doctor rule out that your symptoms could be due to a narrowing or blockage in your heart arteries. The test is simple and convenient and, most importantly, takes into consideration cardiovascular differences between men and women.

With valuable information from the Corus CAD test, your doctor can assess the likelihood that you have a significant narrowing or blockage in your heart arteries. This can help your doctor determine whether further cardiac testing, such as imaging involving radiation, and even invasive procedures or surgery, is warranted. Not only may this help you achieve peace of mind sooner, but avoiding these tests may help you minimize exposure to potentially unnecessary and harmful radiation.

If you think you're experiencing symptoms of obstructive CAD, talk with your doctor and ask if Corus CAD is right for you.


* Obstructive CAD is defined as at least one atherosclerotic plaque causing ≥50% luminal diameter stenosis in a major coronary artery (≥1.5 mm lumen diameter) as determined by invasive quantitative coronary angiography or coronary computed tomography angiography (≥2.0 mm lumen diameter).

Sensitivity of MPI in women demonstrated to be 78% vs. 85% in men. Sensitivity of stress EKG in women demonstrated to be 61% vs. 68% in men.
