All About Heart Attacks

Heart attacks are the leading cause of death in the United States. Heart attacks are caused by blockage in the arteries that carry blood to parts of the heart. When an artery gets blocked, the part of the heart that the artery is going to gets none of the blood and oxygen it needs, and that part of the heart dies. If a small part of the heart dies, the heart can remain alive without it. But if a big part of the heart dies, it can cause death. The blockage in the arteries is caused by build up of fat in an artery. The build up of fat is called a plaque. Plaques look like the globs of fat on a piece of raw chicken. Heart attacks can also be due to a blood clot.
When you have a heart attack, many people describe it as "feeling like there is a heavy weight on top of your chest." It also feels like having bad heartburn, sharp pain or pressure on the chest. You may also have shortness of breath for more than a couple seconds and nausea for more than a couple of seconds. Family history plays a factoring role in the whether or not you will have a heart attack. If a close relative has ever had a heart attack, you might want to take extra precautions because you are at higher risk of having a heart attack. People who are obese also have a higher risk of having a heart attack because they have more fat than most people and fat is what causes arteries to clog up and result in a heart attack. Most people who regularly exercise will not have a heart attack, because exercising burns off fat, and they also have a slower heart rate.
Some people have to have heart surgery, called bypass surgery. Bypass surgery is the process of widening or replacing arteries going to the heart. Many people who get this surgery would have died of a heart attack without it. You should get regular checkups to prevent a heart attack. You should also keep your weight down and exercise regularly.
