What is the composition of arterial deposits?

Arterial deposits, often referred to as atherosclerotic plaques, primarily consist of lipids, cholesterol, and fatty substances, along with cellular components such as smooth muscle cells, macrophages, and inflammatory cells. These deposits can also contain fibrous tissue and calcium, which contribute to plaque stability and hardening of the arteries. The accumulation of these materials leads to the narrowing of arterial walls and can result in cardiovascular diseases.
