Atherosclerosis

Atherosclerosis is a form of arteriosclerosis in which the atheromatous plaques form in the internal layer (intima) of arteries.

Consequences of atherosclerosis

Atheromatous plaques form a lesion in the intima. This leads to recruitment of cells, lipids and other debris that accumulates. Atheroma can develop to the point of causing clot formation (thrombosis) and increasingly obstructing blood circulation. The clot may detach and cause a myocardial infarction or CVA.

Risk factors for atherosclerosis

The risk factors for atherosclerosis are smoking, cholesterol, and hypertension. Risks can be reduced by adopting a better lifestyle although medical and surgical treatments are also available.
