Oxidized LDL is a modified form of LDL cholesterol that has been damaged by free radicals. Unlike standard LDL, oxidized LDL is actively taken up by immune cells in artery walls, triggering the inflammatory cascade that leads to atherosclerotic plaque. It is considered a more direct measure of cardiovascular risk than total LDL alone. Elevated oxidized LDL is associated with metabolic syndrome, diabetes, smoking, and diets high in processed foods.
Cardiovascular biomarkers identify hidden risk for heart attack and stroke years before symptoms appear, allowing for earlier intervention with diet, exercise, or medication.
Adults 35+ for routine cardio screening, anyone with family history of premature heart disease, and patients tracking response to statins, lifestyle changes, or other cardiovascular therapy.
