Carotid artery disease is a blockage in the carotid artery caused by plaque buildup over time. This plaque tends to narrow the arteries, making the flow of oxygen to other parts of the body difficult, which ultimately increases the risk for a stroke.
People with carotid artery disease may not experience any signs or symptoms until the carotid arteries have severely narrowed or become blocked. Sometimes, a stroke
could be the first indication of the disease.
