Remnant cholesterol, also known as remnant lipoprotein, is a very atherogenic lipoprotein composed primarily of very low-density lipoprotein (VLDL) and intermediate-density lipoprotein (IDL).[1] Stated another way, remnant cholesterol is all plasma cholesterol that is not LDL cholesterol or HDL cholesterol,[1] which are triglyceride-poor lipoproteins.[2] However, remnant cholesterol is primarily chylomicron and VLDL, and each remnant particle contains about 40 times more cholesterol than LDL.[3]

According to one study, high remnant cholesterol is more predictive of myocardial infarction than any other lipid particle.[4] Remnant cholesterol is especially predictive of coronary artery disease in patients with normal total cholesterol.[5][6]

High plasma remnant cholesterol is associated with increased plasma triglyceride levels.[7] Hypertriglyceridemia is characteristic of high plasma remnant cholesterol, but persons with high plasma triglycerides without high remnant cholesterol rarely have coronary artery disease.[8]

Remnant cholesterol has about twice the association with ischemic heart disease as LDL cholesterol.[9] Although remnant cholesterol tends to be higher in people who are overweight (high body mass index), normal-weight persons with high remnant cholesterol tend to have a higher risk of myocardial infarction.[10]

Remnant cholesterol is associated with chronic inflammation, whereas LDL cholesterol is not.[11][2]
