Patients - Oxidized LDL Information Print
Oxidized LDL (OxLDL) is a precursor to hardening of the arteries (atherosclerosis). Its presence is an early indicator of high blood pressure (hypertension), possible heart attack, stroke, and diabetes. It comes from the wall of the early damaged artery. If elevated, the doctor can help the patient change diet and life style to possibly prevent hypertension, heart attack, stroke, and diabetes. A simple blood test could change the direction of patient's health.

Testing for atherosclerosis risk factors generally look at correlates of the disease such as elevations of LDL or lowering of HDL cholesterol. The test for OxLDL is unique as OxLDL is both a biomarker and a contributing factor in the formation of atherosclerosis (Ishigaki et al. 2009).

Low density lipoprotein (LDL) is actually a complex of lipids and proteins and is the major carrier of cholesterol to maintain normal cell functions. Under conditions with excess lipids (hypercholesterol), excess oxidative stress or genetic abnormalities, specific components of LDL can become altered or oxidized and the transport of cholesterol is disrupted. The OxLDL is then recognized by the clean up cells of the body called macrophages, which begin to engulf and remove the OxLDL. However, as the level of OxLDL increases, the macrophage cells cannot work properly and become laden with the foamy looking cholesterol from the LDL complex. These 'foam cells' lead to damage to the macrophage cells, the accumulation of cholesterol and oxidized LDL in the wall of arteries and a persistent inflammation that is known as atherosclerotic plaque (Miller et al. 2010).

Large studies have demonstrated that elevations of OxLDL levels are correlated with the progression of heart disease and that the ratio of OxLDL/HDL has the best correlation of the progression of heart disease. There are additional studies showing correlation of OxLDL with metabolic syndrome  as well as diabetes and obesity. As with any lab test, the results of the OxLDL test needs to be correlated with the clinical condition and the evaluation a physician before any diagnosis can be made.
