Lp-PLA2 (PLAC)

Lp-PLA2 is a biomarker released by immune cells specifically in blood vessels to cause inflammation. As vascular inflammation is associated with cardiovascular disease, measuring Lp-PLA2 levels is an accurate indicator of the risk of heart disease¹. Elevated blood levels of this biomarker increase your risk of atherosclerosis, chronic ischaemic heart disease, and stroke²,³. Atherosclerosis is a condition characterized by plaque deposits in your arteries, which increases your risk of experiencing blood clots. Half of heart attacks occur in people with normal cholesterol levels, making this an important additional test for cardiovascular health.

Lp-PLA2 can be used along with other biomarkers to assess your risk for cardiovascular disease. To decrease your risk, healthcare professionals may recommend you eat less fatty foods, exercise more frequently, and, possibly, take statins, which lower levels of cholesterol in your body.
