Atherosclerosis

Atherosclerosis is a disease in which plaque builds up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body. Plaque is made up of fat, cholesterol , calcium and other substances found in the blood. Over time, plaque hardens and narrows your arteries, limiting the flow of oxygen-rich blood to your organs and other parts of your body. This can lead to serious problems, including heart attack, stroke, or even death.

This disease can affect any artery in the body, including arteries in the heart, brain, arms, legs, and pelvis. As a result, different diseases may develop based on which arteries are affected. When blood flow to your heart muscle is reduced or blocked, it can lead to angina (chest pain) and a heart attack. CHD also is called coronary artery disease or heart disease. It's the leading cause of death for both men and women in the United States.

The cause of this disease isn't known. However, certain traits, conditions, or habits may raise your risk for the disease. These conditions are known as risk factors. You can control some risk factors, such as lack of physical activity, smoking, and an unhealthy diet. Others you can't control, such as age and a family history of heart disease.

Some people who have this disease have no signs or symptoms. They may not be diagnosed until after a heart attack or stroke. The main treatment is lifestyle changes. You also may need medicines and medical procedures. These treatments, along with ongoing medical care, can help you live a healthier life.
