Oxidized phospholipids are found on all apoB-containing lipoproteins, namely, LDL, VLDL, and especially Lp(a). When taken up by the artery wall, oxidized lipoproteins accelerate atherosclerosis, thereby, increasing the risk of myocardial infarctions, strokes, and calcific aortic valve stenosis. Oxidized phospholipids are highly pro-inflammatory and contribute to many diseases of aging.
Clinicians can use OxPL-apoB levels to reclassify patients into higher or lower risk categories allowing better personalized care.
Optimal: <2.0 nM/L
Borderline: 2.0-3.0 nM/L
Increased Risk: >3.0 nM/L
