Atherosclerosis
- age, lifestyle, diet, and gene related degeneration of arteries due to deposition of lipoid plaques (atheromas) on inner arterial walls; main cause of coronary artery disease, a leading cause of death.

Generalized and unspecified atherosclerosis
- 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).
