Definition


Arteriosclerosis is a term historically used to describe the thickening of the arterial lining in general, whatever its cause. Today, arteriosclerosis indicates more specifically a "normal" aging of the lining of the arteries affecting mainly the muscular arteries and the renal arteries (hypertensive nephropathy). It is differentiated from atherosclerosis which is a chronic arterial disease characterized by the build-up of lipids in the arteries related to elevated levels of cholesterol in the blood.
