What causes atherosclerosis?
Atherosclerosis is caused by the accumulation in the bloodstream of fat, cholesterol, and other substances that build up on the walls of arteries and form hard structures called plaques. Plaque narrows and stiffens the arteries, making it difficult for blood to flow through the artery. In addition, pieces of plaque can break off and travel through the affected artery (embolize) and lodge in smaller blood vessels, blocking them and causing tissue damage, which may be life threatening. Atherosclerosis occurs most often in people who have a family history of heart disease or other risk factors for the development of atherosclerosis.
