Rule-out of non-ST-segment elevation acute coronary syndrome by a single, pre-hospital troponin measurement: a randomized trial

Eur Heart JPublished

  • Randomised controlled trial
  • investigator-initiated
  • 5 ambulance regions in the Netherlands

Authors' conclusion

Pre-hospital rule-out of ACS with a POC troponin measurement in low-risk patients significantly reduces healthcare costs while incidence of MACE was low in both strategies.
