What is the events occurring in the heart during a heart attack?
During a heart attack your heart muscle is starved for oxygen,
therefore it goes into spasm, that's why your chest hurts and your
pulse rises. Also, your heart is not pumping efficiently, because
it's going too fast, and the blood is not oxigenated properly in
the lungs (that's what causes patients to hyperventilate), so you
can faint or become unconcious because not enough blood is reaching
Heart attack risk goes up in men over 45 and women over 55 but heart attacks can happen at any age.
You get the heart attack, because of lack of exercise. Exercise keeps your heart and circulatory system, healthy. If your circulatory system is defective, you may get heart attack during sleep also. So many times you wake up in the morning to find that you are dead due to heart attack, that you got during the sleep. :)
There is a big difference between heartburn and a heart attack. There are symptoms of a heart attack which may seem to resemble the pains associated with heartburn but heartburn usually appears after eating or while lying down and heart attack symptoms usually start as a crushing pain in the center of the chest which radiates outwards. The left arm is usually affected during heart attack pains.
