Heart Attack Warning Signs

Most people miss the signs. Could you spot a heart attack?

Here are five warning signs, and when to call 911.

A heart attack does not always feel like the movies. Many older adults miss it. Catching it early saves lives.

Sign one. Chest pressure. It may feel like squeezing, fullness, or pain in the center of your chest.

Sign two. Short of breath. You may feel you can't catch your breath, even at rest, with or without chest pain.

Sign three. Pain that spreads. You may feel it in your arm, jaw, neck, or back, often on the left side.

Sign four. Cold sweat and dizziness. You may feel dizzy, lightheaded, or faint, or break out in a cold, clammy sweat.

Sign five. Sudden fatigue. You may feel unusual, extreme tiredness, even after resting. This one is more common in women.

If you notice any of these signs, here is what to do. Stop what you're doing. Sit or lie down. Call 911 right away. Tell them you may be having a heart attack. Do not wait. And do not drive yourself.

While you wait for help, one little pill can matter, and most use it wrong. See how next.
