Lp‑PLA2 Activity
Also known as: PAF-AH
Use
Lipoprotein‑associated phospholipase A₂ (Lp‑PLA₂), also known as platelet activating factor acetylhydrolase, is an inflammatory enzyme circulating bound mainly to low‑density lipoproteins and localized in atherosclerotic plaques. Elevated Lp‑PLA₂ activity has been shown to independently predict coronary heart disease and stroke risk in the general population, and measuring Lp‑PLA₂ may support identification of individuals at higher cardiovascular risk, potentially guiding initiation or intensification of risk‑reduction strategies.
