Heart Attack Warning Signs

What is a Heart Attack?

A heart attack occurs when an artery that carries blood to your heart becomes blocked, usually by a blood clot. If this clot cuts off the blood flow completely, the part of your heart muscle supplied by the blocked artery begins to die. Damage to the heart muscle increases the longer you delay treatment.

Warning signs of a heart attack:

  • Pain or discomfort in the jaw, neck, or back
  • Feeling weak, light-headed, or faint
  • Chest pain or discomfort
  • Pain or discomfort in arms or shoulder
  • Shortness of breath

Act Fast. Call 9-1-1!

  • If you think you're having a heart attack, call 9-1-1 right away– not a friend.
  • Calling 9-1-1 is the best way to get to the hospital.
  • Emergency medical services (EMS) staff can begin life-saving treatment immediately.
  • You’re likely to receive faster treatment at the hospital if you arrive by ambulance.
  • Never drive yourself or have someone drive you to the hospital unless you have no other option.
