What does atherosclerosis mean?

Plaque build up. It is hardening of the arteries, caused by fat, cholesterol, and other substances building up in the arteries - this is called plaque - making the arteries stiffer.

The plaque can block the arteries and/or it can break off and flow to smaller vessels and block them.
Disease, Artery Wall. Atherosclerosis results from an accumulation of white blood cells, mostly macrophages (called monocytes, one of 5 white blood cell types), which have invaded into the walls of the blood vessel to remove low density lipoprotein (fat carrying protein) particles. The macrophages may die if overwhelmed with LDL & cannot export the ingested fat into high density lipoprotein particles.
