Atherosclerosis is a type of thickening or hardening of the arteries caused by a buildup of plaque in the inner lining of an artery.
Plaque is made up of deposits of fatty substances, cholesterol, cellular waste products, calcium, and fibrin, and can develop in medium or large arteries causing the artery wall to become thickened and stiff.
Atherosclerosis is a slow, progressive disease that may start as early as childhood. However, the disease has the potential to progress rapidly.
It is unknown exactly how atherosclerosis begins or what causes it. However, there is a gradual buildup of plaque or thickening of the inside of the walls of the artery. This causes a decrease in the amount of blood flow, and a decrease in the oxygen supply to the vital body organs and extremities.
Certain risk factors are associated with atherosclerosis, including:
Signs and symptoms of atherosclerosis may develop gradually, and may be few, as the plaque builds up in the artery. Symptoms may also vary depending on the affected artery. However, when a major artery is blocked, signs and symptoms may be severe, such as those occurring with heart attack, stroke, aneurysm, or blood clot.
The symptoms of atherosclerosis may resemble other heart conditions. Consult your health care provider for a diagnosis.
In addition to a complete medical history and physical exam, you may have one or more of these tests:
Specific treatment will be determined by your health care provider based on:
Treatment may include:
Risk factors that may be modified include smoking, high cholesterol levels, high blood glucose levels, lack of exercise, poor dietary habits, and high blood pressure.
Medicines that may be used to treat atherosclerosis include:
With this procedure, a balloon is used to create a bigger opening in the vessel to increase blood flow. Although angioplasty is performed in other blood vessels elsewhere in the body, percutaneous coronary intervention (PCI) refers to angioplasty in the coronary arteries to permit more blood flow into the heart.PCI is also called percutaneous coronary intervention. There are several types ofPCI procedures, including:
Most commonly referred to as bypass surgery, this surgery is often done in people who have angina (chest pain) due to coronary artery disease (where plaque has built up in the arteries). During the surgery, a bypass is created by grafting a piece of a vein above and below the blocked area of a coronary artery, enabling blood to flow around the obstruction. Veins are usually taken from the leg or from the chest wall.
As a result of the plague buildup inside of the arteries, the blood flow within these arteries is reduced. A heart attack may occur if the oxygenated blood supply is reduced to the heart. A stroke may occur if the oxygenated blood supply is cut off to the brain. Severe pain and tissue death may occur if the oxygenated blood supply is reduced to the arms and legs.
Atherosclerosis may be prevented or delayed by reducing risk factors. This includes adopting a healthy lifestyle. A healthy diet, losing weight, being physically active, and not smoking can help reduce your risk of atherosclerosis. A healthy diet includes fruits, vegetables, whole grains, lean meats, skinless chicken, seafood, and fat-free or low-fat dairy products. A healthy diet also limits sodium, refined sugars and grains, and solid fats.
If you are at risk for atherosclerosis because of family history, or high cholesterol, it is important that you take medications as directed by your health care provider.
If your symptoms get worse or you have new symptoms, let your health care provider know.
