An expedited pre-hospital pathway significantly reduced door-to-balloon times for ST-segment elevation myocardial infarction (MI) patients. This approach improved timely reperfusion, crucial for better patient outcomes in urban settings.

Area of Science:

  • Cardiology
  • Emergency Medicine
  • Healthcare Systems

Background:

  • Rapid reperfusion is critical for ST-segment elevation myocardial infarction (MI) patient outcomes.
  • Primary percutaneous coronary intervention (PCI) is the preferred reperfusion strategy when timely and effective.
  • Evaluating pre-hospital interventions to reduce delays in MI treatment is essential.

Purpose of the Study:

  • To assess the impact of a new pre-hospital diagnosis and transfer pathway on door-to-balloon times.
  • To determine the feasibility of implementing such a pathway in a large urban community.
  • To improve the delivery of primary PCI for ST-segment elevation MI.

Main Methods:

  • A prospective study of ST-segment elevation MI patients presenting within 12 hours of symptom onset.

  • Inclusion of patients utilizing Emergency Medical Services in Calgary over 16 months post-pathway implementation.
  • Primary endpoint: proportion of patients receiving PCI within 90 minutes of hospital arrival.

    • Main Results:

    • The implemented pathway achieved a median door-to-balloon time of 62 minutes.
    • 48.9% of patients achieved PCI within 60 minutes; 78.8% within 90 minutes.
    • In-hospital and 30-day mortality rates were both 3.1%.

    Conclusions:

    • A multidisciplinary pre-hospital pathway is feasible in an urban setting with multiple hospitals.
    • The pathway effectively reduced door-to-balloon times, meeting recommended targets for most patients.
    • This strategy facilitates timely primary PCI, potentially improving ST-segment elevation MI care.
