Heart Attack (MI - Myocardial infarction)

Every year in excess of a million people in the U.S. have a heart attack. As regards half of them die. Several people have permanent heart damage or die for the reason that they don't get help out immediately. It's significant to know the symptoms of a heart attack

* Shortness of breath

* Discomfort in the upper body - arms, shoulder, neck, back
