Coronary Artery Disease
Heart Disease
Heart disease can take many forms. The form of heart disease I am focusing on is coronary disease. Different arteries supply different areas of the heart with oxygenated blood. If one or more of these arteries become narrowed or clogged as a result of coronary artery disease, or atherscelorosis the artery cannot fully supply the part of the heart it is responsible for. The heart is an effective pump only when good blood supply is maintained to all heart muscles.
If an artery becomes so clogged that blood cannot flow through it, the result is chest pain which could progress to a heart attack, or myocardial infarction (MI). "Myocardial" is a medical term that means "having to do with the heart" or "heart muscle". "Infarct" is a medical term for tissue death. During a myocardial infarction, the portion of the heart that is supposed to get blood from the diseased artery dies. However, cardiologists are trained to recognize symptoms like chest pain, shortness of breath, and fatigue of coronary artery disease in patients before the symptoms becomes severe. A cardiologist is often able to treat coronary disease before it causes an MI. – http://myweb.com/contents/dmk_article396168

Coronary Artery Disease
Healthy arteries are flexible, strong, and elastic. Their inner layer is smooth and blood flows freely. As you get older, your arteries become thicker, less elastic, and deposits build in them. This leads to a general hardening of the arteries, which is also called atherosclerosis.
Atherosclerosis or arteriosclerosis is the main cause of coronary artery disease. Atherosclerosis or arteriosclerosis is the gradual buildup of cholesterol inside the artery. When this happens in a coronary artery, the space inside the artery where blood flows becomes narrow, making it difficult for blood to flow freely. The result is less...
