In the modern ST-elevation myocardial infarction (STEMI) system, the use of electrocardiogram by emergency medical services (EMS) personnel and the option to bypass emergency departments on route to a PCI-capable hospital is of particular importance. Through training and a standardized referral process, EMS personnel can now accurately diagnose and refer STEMI patients directly to the catheterization laboratory of a percutaneous coronary intervention-capable hospital. Regional STEMI models have been implemented successfully across North America, resulting in palpable reductions in door-to-balloon time, morbidity, and mortality.
