Study: Few Know Heart Attack Warning Signs ATLANTA, GA (Associated Press) -

Only about 1 in 4 Americans know the warning signs of a heart attack, U.S. health officials in Atlanta say.

Most are also unaware that the first thing to do is call 9-1-1. Doctors with the Centers for Disease Control and Prevention said the level of public awareness is alarmingly low.

The warning signs include shortness of breath; pain in the chest, arms or shoulder; a feeling of weakness; and discomfort in the jaw, neck or back. Each year more than 900,000 Americans suffer a heart attack.
