Warning Signs of a Heart Attack

Cardiac Arrest Warning Signs
Cardiac arrest strikes immediately and without warning. Here are the signs:

Sudden loss of responsiveness. No response to gentle shaking.
No normal breathing. The victim does not take a normal breath when you check for several seconds.
No signs of circulation. No movement or coughing.

Heart Attack Warning Signs
Here are signs that can mean a heart attack is happening:

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. This feeling often comes along with chest discomfort. But it can occur before the chest discomfort.
Other signs: These may include breaking out in a cold sweat, nausea or lightheadedness.

If you or someone you're with has chest discomfort, especially with one or more of the other signs, don't wait longer than a few minutes (no more than 5) before calling for help. Call 9-1-1... Get to a hospital right away.

Calling 9-1-1 is almost always the fastest way to get lifesaving treatment. Emergency medical services staff can begin treatment when they arrive -- up to an hour sooner than if someone gets to the hospital by car. The staff are also trained to revive someone whose heart has stopped. Patients with chest pain who arrive by ambulance usually receive faster treatment at the hospital, too.

If you can't access the emergency medical services (EMS), have someone drive you to the hospital right away. If you're the one having symptoms, don't drive yourself, unless you have absolutely no other option.
