Summary

This study looks at whether a simple blood test done in the ambulance can safely rule out a heart attack in people with chest pain. Many patients are taken to the hospital even though they are not having a heart attack. The test uses a portable device to measure a heart protein called troponin. The results will not change care during the study but will help researchers see if this approach could reduce hospital visits in the future.

Who can take part

Who is studied

Patients are recruited from the prehospital emergency medical services (EMS) system in the Central Denmark Region, Denmark. Participants are identified during routine ambulance missions by EMS personnel in units equipped with point-of-care testing (POCT) devices and trained in study procedures. The study population reflects real-world prehospital patients encountered in a publicly funded, tax-supported healthcare system with universal access to emergency care. Patients are included consecutively during the study period based on operational availability of participating EMS units.
