Scope Note
thickening and loss of elasticity of arterial walls; atherosclerosis is the most common form of arteriosclerosis and involves lipid deposition and thickening of the intimal cell layers within arteries; additional forms of arteriosclerosis involve calcification of the media of muscular arteries (Monkeberg medial calcific sclerosis) and thickening of the walls of small arteries or arterioles due to cell proliferation or hyaline deposition (arteriolosclerosis).

- Arteriosclerosis is often referred to as "hardening of the arteries.
- Arteriosclerosis is a vague term that may be used to describe several types of conditions that affect the arteries.
- Hyperplastic arteriosclerosis is characterized by a pattern of thickening commonly likened to an onion skin, concentric laminations of smooth muscle cells and basement membranes being deposited one on top of the other in layers.
- Arteriosclerosis is usually preceded by atherosclerosis, a kind of fatty infiltration in the inner lining of the blood vessel walls.
- Although the relationship between blood cholesterol levels and arteriosclerosis is not fully understood, the utilization of low-density lipids appears to be a primary indicator of the risk of arteriosclerosis.
