Non-HDL cholesterol as a measure of atherosclerotic risk.
Elevated triglyceride (TG) and low high-density lipoprotein cholesterol (HDL-C) levels, hallmarks of the atherogenic lipid profile found in the metabolic syndrome and type 2 diabetes, are commonly seen in Japanese patients with coronary heart disease (CHD). In the setting of mildly to moderately elevated plasma TG (150-500 mg/dl), very-low-density lipoprotein (VLDL) accumulates and so do high levels of atherogenic TG-rich, cholesterol-enriched remnant particles. Indeed, in hypertriglyceridemia, abnormalities are seen in the quantity and quality of all lipoprotein B-containing lipoproteins. Non-HDL-C (total cholesterol minus HDL-C) provides a convenient measure of the cholesterol content of all atherogenic lipoproteins, and thus incorporates the potential risk conferred by elevated levels of atherogenic TG-rich remnants that is additional to the risk associated with low-density lipoprotein cholesterol (LDL-C). Non-HDL-C level has been found to be a strong predictor of future cardiovascular risk among patients whether or not they exhibit symptoms of vascular disease, and was recently recommended as a secondary treatment target (after LDL-C) in patients with elevated TG by the National Cholesterol Education Program Adult Treatment Panel III. Adoption of this readily available measure to assess risk and response to treatment in patients with elevated TG would improve treatment of dyslipidemia in a substantial number at risk for CHD.
