Carotid Artery Disease
Carotid Artery Disease Carotid artery disease occurs when the arteries that carry blood from the heart to the brain become narrowed. As with other vascular diseases, narrowing of the carotid arteries is most commonly caused by atherosclerosis, sometimes referred to as hardening of the arteries. Atherosclerosis is a gradual process in which cholesterol accumulates to form a plaque that clogs the blood vessels. Carotid artery disease can cause a stroke if blood flow is cut off, leading brain cells to die and impairing body parts that those brain cells control.
