What does hdl do to ldl?

Pacman: Did you ever play pacman? Hdl is the LDL eating pacman. It helps decrease the total circulating LDL molecules and deliver them to the liver for storage and or disposal. You can not form plaques without inflammation of blood vessel walls and ldl(among other things). So the lower the circulating LDL levels are, the longer it takes to develop blocked arteries.

Nothing - Opposites: Lipoproteins are complex particles which carry fat molecules in the water outside cells. Generally, LDL particles deliver fat molecules into cells; HDL particles can remove fat molecules from cells. Too many LDL particles entering artery walls create problems & wbcs attempt to remove them. Without functioning HDL to remove fat from the wbcs, the wbcs die & this is called atherosclerotic plaque.

Influences Risk: Hdl does not directly affect the production or clearance of ldl, although both lipoproteins are important in understanding risk for heart attack and stroke. Cardiovascular (cvd) risk is related to the number of LDL particles (ldl-p) and the number of HDL particles (hdl-p). Lowering high ldl-p is the primary goal of therapy. When ldl-p is at goal, cvd risk is still high with low hdl-p.
