PLAC Test – a clever way to check your cardiovascular risk

Cholesterol testing alone is not enough - 50% of heart attacks occur in patients with normal cholesterol.

Arteries are blood vessels that supply oxygen-rich blood to your heart and other parts of your body. Atherosclerosis is a disease in the arteries in which the build-up of plaque can decrease blood flow to the heart or brain.Plaque is made up of fat, cholesterol and other substances found in the blood. Over time, the amount of plaque can increase, causing narrowing of the arteries. When this happens, it is more difficult for the blood to flow.

The majority of heart attacks and ischaemic strokes are caused by ruptured plaques.

When the plaque ruptures, the flow of blood to the heart or brain can become blocked, which results in a heart attack or stroke. 

The PLAC Test goes beyond what routine cholesterol testing can do by identifying active cardiovascular inflammatory disease. The PLAC Test measures an enzyme that, when elevated, indicates arterial inflammation, making heart attack or stroke more likely.The PLAC Test provides additional information that, when combined with standard cholesterol tests and an exam, can help determine whether or not you are at an increased risk for a heart attack or stroke.

A PLAC test can be useful if you have two or more of the following risk factors:

  • Male 45 years or older or female 55 years or older
  • Family history of early heart disease or stroke
  • Diabetes
  • Obesity
  • Smoker
  • Borderline high or elevated cholesterol levels

The PLAC test is part of our Comprehensive Heart Risk Assessment.
