Atherosclerosis

Definition

Atherosclerosis is a condition in which fatty material collects along the walls of arteries. This fatty material thickens, hardens (forms calcium deposits), and may eventually block the arteries.

Atherosclerosis is a type of arteriosclerosis. The two terms are often used to mean the same thing.

Symptoms

Symptoms usually do not occur until blood flow becomes restricted or blocked.
