Atherosclerosis is a condition that occurs when the inside of the arteries, the blood vessels that carry blood from the heart to the rest of the body, becomes thickened. This can lead to abnormal stiffening and narrowing of the arteries. The condition can start as early as childhood and can lead to many health conditions, including heart disease and stroke.
Atherosclerosis is a disease that develops slowly over time. Excess cholesterol and other substances in the blood form plaques, which line the inner surface of the arteries. Plaques vary in their composition; some are hard and contain relatively large amounts of calcium, and others are soft, made mostly of semi-liquid cholesterol and inflammatory cells that are contained by a fibrous "cap." Atherosclerosis can lead to narrowing of the arteries, which makes it more difficult for blood to carry oxygen and nutrients to the brain, heart, kidneys, and other organs. If the fibrous cap of soft plaque ruptures, these contents enter the bloodstream, causing the body to form a blood clot to block them off. This can lead to a heart attack, stroke, or other serious or even life-threatening problem with the circulation. Diseases caused by atherosclerosis are the leading cause of death in the United States.
Certain risk factors increase the chance of developing atherosclerosis. These include high blood pressure, high cholesterol, diabetes, and obesity, which are also components of the metabolic syndrome. So managing the components of the metabolic syndrome can also help reduce your risk for atherosclerosis. This, in turn, can help prevent the heart conditions that can result. Getting regular exercise; eating a diet low in fat, salt and cholesterol; quitting smoking (if you smoke); managing high blood pressure; and reducing stress are a few of the lifestyle changes that can help reduce your chance of developing these health risks. Working with your health care provider to keep your risk factors low is important. Age and a family history of early heart disease are also risk factors for atherosclerosis.
Treatment for atherosclerosis starts with a healthy diet, physical activity, and a smoke-free lifestyle. Certain medications can help lower cholesterol and blood pressure. These medications can slow or even reverse the condition. If you have or are at high risk for atherosclerosis, your health care provider can recommend which treatment is best for you.
