Heart disease is America’s No.1 killer. Each year more than one million Americans have a heart attack and more than half die, usually within the first hour and before reaching the hospital.

Know the warning signs of a heart attack and if you have any of the symptoms, call 9-1-1. Do not delay because you think it might be indigestion. Getting early treatment can prevent or limit the damage to the heart and prevent death.

Here are the Warning Signs of Heart Attack according to the American Heart Association:

*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.

* 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.

* Shortness of breath. May occur with or without chest discomfort.

* Other signs: These may include breaking out in a cold sweat, nausea or lightheadedness

If you think you or someone else is having a heart attack, get emergency help, call 9-1-1. They have trained personnel with necessary drugs and equipment. The sooner you get help and treatment, the greater the chances you can avoid permanent heart damage or death.
