What is a STEMI heart attack?

STEMI (ST segment elevation myocardial infarction) is a heart attack where the coronary artery is completely blocked by a blood clot, and the heart muscle starts to die.

You may begin to have symptoms to the extent that you're concerned about having a heart attack in your home. If this is the case, you should call 911. Emergency medical services (EMS) will do an electrocardiogram (EKG) that is electronically transmitted to the hospital where the emergency room doctor, along with the EMS personnel, can make a decision as to whether to activate the Code STEMI program. This activates the appropriate healthcare team for your treatment when you arrive at the emergency room.

STEMI stands for ST elevation myocardial infarction. This heart attack causes a specific change in a patient's EKG that suggests one or more blockages in the coronary arteries.
