The Basics
What is a heart attack?
A heart attack happens when blood flow to the heart is blocked. Parts of the heart muscle may die.
Signs of a heart attack include:
- Chest pain, like uncomfortable pressure or squeezing
- Trouble breathing
- Pain or discomfort in the upper body, like the arms, back, neck, or jaw
Not everyone who has a heart attack will have the same signs. Know the other common signs of a heart attack. Call 911 right away if you think you or someone else is having a heart attack.
