Heart Attack

If you think you or someone you are with is having a heart attack, call 9-1-1. 

What Is a Heart Attack?

A heart attack occurs when the flow of blood to a section of the heart becomes blocked. Some heart attacks happen suddenly and are intense, sometimes accompanied by chest pain. Most heart attacks, however, start slowly with mild pain and discomfort. Symptoms can be different between men and women. 

Other names for heart attack include:

  • Myocardial Infarction (MI)
  • Acute Coronary Syndrome
  • Coronary Thrombosis
  • Coronary Occlusion

The longer an artery stays blocked the more damage can occur. Speed is the key to diagnosis and, if you need it, treatment and can lead to your full recovery. You can count on the heart specialists at Banner Health to quickly assess your symptoms and deliver the treatment you need — right when you need it.
