How do you get rid of the cholesterol that already clogs your arteries?

Tough luck : Once atherosclerosis has established in a vessel wall there is very little medication can do to significantly reduce it. On the other hand, if it is not causing symptoms now, you can stop it in its tracks by reducing your risk factors like smoking, high blood pressure, high cholesterol, diabetes and obesity.

LDLHDLnotCholesterol: Several ways. Cholesterol: fat molecule manufactured by every animal cell, building block of each cell membrane (enables membrane fluidity/movement without tearing), fundamental to survival of every animal cell. Lipoproteins (proteins which transport all fats in the water outside cells) is the correct issue for artery disease (e.g. Ldl ≤400 nmol/l, HDL ≤45 µmol/l). Cholesterol ↓$, but misleading.
