What is Atherosclerosis?
Atherosclerosis is a condition in which fatty deposits, known as plaque, build up in the walls of the arteries. This buildup narrows the arteries, reducing the flow of blood and oxygen to organs and other parts of the body. Atherosclerosis can lead to a number of serious health problems, including heart attack and stroke.
Which Organs Are Affected by Atherosclerosis?
Atherosclerosis can affect any artery in the body, but it is most commonly found in the arteries of the heart, brain, legs, and arms.
Heart: Atherosclerosis in the arteries of the heart, known as coronary artery disease (CAD), is the leading cause of death in the United States. Plaque buildup in the coronary arteries can lead to chest pain (angina), heart attack, and death.
Brain: Atherosclerosis in the arteries of the brain can lead to stroke. A stroke occurs when a blood vessel in the brain is blocked or ruptures, depriving brain tissue of oxygen and nutrients. Symptoms of stroke include sudden weakness or numbness, confusion, and difficulty speaking.
Legs and Arms: Atherosclerosis in the arteries of the legs and arms can lead to peripheral arterial disease (PAD). PAD is a condition in which the blood flow to the legs and arms is reduced, causing pain and cramping in the affected areas.
