PreHEART score for emergency medical services triage of chest pain: a randomised trial

HeartPublished

  • Pragmatic, randomised, open-label, blinded-endpoint non-inferiority trial
  • conducted in the Netherlands by Emergency Medical Services

Authors' conclusion

PreHEART-guided EMS conveyance was non-inferior to usual care for serious adverse events, reduced emergency department presentations and costs, and was associated with increased ACS detection and coronary angiography in women.
