What is Atherosclerosis?
Atherosclerosis (also known as arteriosclerotic vascular disease or ASVD) is a condition in which an artery wall thickens as a result of the accumulation of fatty materials such as cholesterol. It is a syndrome affecting arterial blood vessels, a chronic inflammatory response in the walls of arteries, caused largely by the accumulation of macrophage white blood cells and promoted by low-density lipoproteins (plasma proteins that carry cholesterol and triglycerides) without adequate removal of fats and cholesterol from the macrophages by functional high density lipoproteins (HDL). It is commonly referred to as a hardening or furring of the arteries. It is caused by the formation of multiple plaques within the arteries.
Is a muscle about the size of your fist
Weighs approximately one pound
Is located behind and slightly to the left of the breastbone
Pumps about 5 quarts (4.7 liters) of blood every minute
The function of the heart is to circulate blood throughout the body by:
- Pumping blood through the lungs removes carbon dioxide and refreshes the blood with oxygen
- The oxygenated blood is pumped to the body to provide oxygen and nutrients and to remove waste products.
- The coronary arteries are the blood vessels that supply blood and oxygen to the heart muscle.
Coronary Artery Disease
Coronary artery disease is one of the most common and serious effects of aging. Fatty deposits build up in blood vessel walls and narrow the passageway for the movement of blood. The resulting condition, called atherosclerosis often leads to eventual blockage of the coronary arteries and a “heart attack”.
Signs and Symptoms
None: This is referred to as silent ischemia. Blood to your heart may be restricted due to CAD, but you don’t feel any effects.
Chest pain: If your coronary arteries can’t supply enough blood to meet the oxygen demands of your heart,
the result may be chest pain called angina.
Shortness of breath: Some people may not be aware they have CAD until they develop symptoms of congestive heart failure- extreme fatigue with exertion, shortness of breath and swelling in their feet and ankles.
Heart attack: Results when an artery to your heart muscle becomes completely blocked and the party of your heart muscles fed by that artery dies.
- High blood cholesterol
- High blood pressure
- Lack of physical activity
Many people are able to manage coronary artery disease with lifestyle changes and medications.
Other people with severe coronary artery disease may need angioplasty or surgery.
