    Cardiac Emergency Care

    If you are experiencing chest pain, shortness of breath or fatigue that does not go away with rest, call 911 immediately.

    St. Anthony Summit Medical Center utilizes the latest evidence-based medicine for emergency response care for heart attack victims. A team of highly trained emergency physicians and nurses respond immediately to all patients presenting to the Emergency Department for potential heart attacks.
