What Is Artery Plaque?
Artery plaque is made up of several substances found in the blood, including fat, cholesterol, cellular waste, fibrin and calcium. These materials build up along the artery walls to form the plaque. Plaque narrows the arteries and can eventually block them. Artery Plaque Causes According to the Heart, Lung and Blood Institute, plaque buildup in the arteries begins with damage to the arteries. Factors such as high blood pressure, smoking, high amounts of certain fats, cholesterol and sugar in the blood can damage the walls of the arteries. To repair the damage, fatty tissues are released to help begin the repair process. In response to the buildup along the walls, the arteries can secrete more substances to add to the plaque buildup, further clogging the artery. Effects There are several dangers associated with plaque buildup in the arteries. Plaque in the arteries carrying blood to the heart can lead to narrow and eventually block the arteries, leading to heart attacks and stroke. If p
