Heart Attack Warning Signs (and What to Do Right Away)

Heart attacks don't always look like the movies. Knowing the signs, and calling for help fast, makes a real difference. Here's what the CDC says to watch for.

1. The Main Sign

A major warning sign is chest pain, or discomfort in the chest.

2. It Can Spread

There can also be pain or discomfort in the jaw, neck, or back, or in one or both arms or shoulders.

3. Other Signs

Watch for shortness of breath, and feeling weak, light-headed, or faint. Some people, more often women, have unusual tiredness, nausea, or vomiting.

4. Call 911 Right Away

If you notice these signs in yourself or someone else, call nine one one right away. The sooner treatment starts, the better the chance of surviving. Don't wait to see if it passes.
