P854 Acute Coronary Syndrome

What is a heart attack? A heart attack occurs when the supply of blood and oxygen to an area of heart muscle is blocked. A heart attack is also known as a myocardial infarction, or MI. Heart attacks are almost always the result of progressive coronary artery disease, or CAD. In CAD, the arteries that supply blood to the heart become clogged with fatty deposits called plaque, which narrows and blocks arteries. This condition is known as atherosclerosis. When pieces of the plaque break free, blood clots can form, blocking the flow of blood to the heart. As a result, the heart muscle does not get the oxygen and nutrients it needs. Parts of the heart may become damaged or die, and symptoms of a heart attack begin. Is it angina or a heart attack? Angina usually goes away after a few minutes of rest. If you have never had angina before or if the following symptoms last for more than a few minutes, or if they go away and come back, you could be having a heart attack.
