HDLs comprise a family of heterogeneous particles that vary by size, density, composition, and functionality. Two distinct HDL subfractions, large buoyant HDL2 and small dense HDL3, might exert differential effects on atherosclerosis and display a promising role in CAD risk prediction.
HDL-2 is part of the larger HDL cholesterol family, which is responsible for removing excess cholesterol from the body and transporting it to the liver. HDL-2 is formed when HDL particles in the blood interact with enzymes and acquire more cholesterol.
The large HDL2 is superior to small HDL3 in the assessment of of coronary artery disease risk.

HDL2 is often thought to be the “protective” form of HDL, and has been shown to have an inverse relationship with the risk of coronary artery disease.
