Heart Attack-Are We At Risk

In one your lifetime, you must ever heard someone said "He was died because of heart attack last night". Then there are someone else said "How can he got a heart attack" and "You must always asking are the heart attack is very dangerous..do I will have heart attack one day..but what is the sign of it and the most important what is the heart attack??"

A heart attack happened when the blood supply to part of the heart muscle itself, the myocardium, is stopped.

The reduction or stoppage happens when one or more of the coronary arteries supplying blood to the heart muscle was blocked. This is usually caused by the buildup of plaque (deposits of fat-like substances), a process called atherosclerosis. The plaque can eventually break into piece, tear or rupture, creating a "snag" where a blood clot forms and blocks the artery. This leads to a heart attack.

If the blood supply is cut off for more than a few minutes, muscle cells suffer permanent injury and die. This can kill or disable someone, depending on how much heart muscle is damaged.

Sometimes a coronary artery temporarily contracts or goes into spasm. When this happens the artery narrows and blood flow to part of the heart muscle decreases or stops. We're not sure what causes a spasm. A spasm can occur in normal-appearing blood vessels as well as in vessels partly blocked by atherosclerosis. A severe spasm can cause a heart attack.

The medical term for heart attack is myocardial infarction. A heart attack is also sometimes called a coronary thrombosis or coronary occlusion.

The sign that you should take care of it if you realize that it is happened to you :

1. Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain.

2. Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw or stomach.

3. Shortness of breath with or without chest discomfort.

4. Other signs may include breaking out in a cold sweat, nausea or lightheadedness.

Please learn the signs of it, and remember this : Even if you're not sure about it, have it checked out and tell the doctor about your symptoms. Don't ever wait a minute it you figure it symptoms. Fast action can save lives.
