Heart Attack Warning Signs

Know the Signs - Get Help Right Away

A heart attack is an urgent message from your heart that it's starved for oxygen. When a clot blocks a heart vessel, oxygen-rich blood can't reach your heart. Then heart muscle begins to die and symptoms of a heart attack begin.

The sooner you get to the hospital, the sooner treatment can start to help save your life and your heart muscle.

Classic Warning Signs

  • 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 with or without chest discomfort.
  • Fainting
  • Other signs may include:
    • cold sweat
    • nausea
    • lightheadedness
    • chills
    • weak pulse

Don't Wait to Get Help!

If you think you or someone you know is having a heart attack

  • Call 911 immediately.

  • Use aspirin, nitroglycerin and beta blockers if you have access to them.
