The PLAC® Test for Lp-PLA2 is the only blood test cleared by the FDA to help assess risk for both coronary heart disease (CHD) and ischemic stroke associated with atherosclerosis.
The PLAC Test is a simple lab test that measures the level of Lp-PLA2 (Lipoprotein-associated Phospholipase A2), an enzyme in your blood that is produced inside the plaque (or fat build up) in the arteries when the arteries are inflamed and the plaque is in danger of rupture. If the amount of Lp-PLA2 is high, this may indicate that the plaque is more likely to rupture through the inside lining of your artery into your bloodstream where it may cause a clot that could result in heart attack or stroke. Increased levels of Lp-PLA2 mean you have an increased risk of having a heart attack or stroke.
The majority of all heart attacks and strokes are caused by plaque rupture resulting in clots, not from narrowing of the arteries.
Early detection and more aggressive treatment can help prevent these cardiovascular events.
