Heart attack care in Salt Lake City

Our emergency room has experience quickly diagnosing and treating heart attacks in Salt Lake City. In the event of a heart attack, every second matters for survival. That's why our hospital’s ER physicians and cardiologists have partnered with local medical response teams to streamline heart attack diagnosis and treatment processes ensuring expedited care for people suffering a heart attack.

12-lead EKG Technology

Heart attack victims being transported via ambulance to St. Mark's Hospital are diagnosed in transit by pre-hospital 12-lead EKG technology. This machine shows a full view of the heart and records its electrical activity. This valuable information is transmitted from the ambulance to emergency room physicians at St. Mark's Hospital to determine if a heart attack has occurred and where in the heart the damage is located. This allows our ER staff and specialists to have a treatment plan ready and a medical team assembled before the patient even arrives.

Bypass the Emergency Room Triage Process

A heart attack victim diagnosed in an ambulance bypasses the emergency room triage process and goes straight to the cardiac catheterization lab, where a medical team stands prepared to insert a balloon to unblock a clogged artery. This streamlined process saves time and lives and helps to reduce long-term heart muscle damage.
