Some factors that may lead to shortening total ischemic time include the following:

  • Prehospital electrocardiography (ECG) to diagnose STEMI to activate the percutaneous coronary intervention (PCI) team while the patient is en route to the hospital
  • Emergency department physicians activate the PCI team
  • A single call to a central page operator who activates the PCI team
  • The goal is set for the PCI team to arrive in the catheterization laboratory within 20 minutes after being paged
  • Timely data feedback and analysis are provided to members of the STEMI care team
