Atherosclerosis is a disease of the vessel wall involving lipidaccumulation, chronic inflammation, cell death, and thrombosisthat causes heart disease and stroke. Although elevated cholesterollevels are a recognized risk factor for atherosclerosis, a growingnumber of studies suggest that oxidized phospholipids may alsoplay an important role in this condition.1,2 Phospholipids,essential components of lipoproteins and cell membranes, arecomposed of fatty acids bound to a glycerol backbone containinga polar head group. They are susceptible to free-radical orenzymatic oxidation by myeloperoxidase, lipoxygenase, and otherenzymes that are present in the vessel wall. The addition ofoxygen . . .
