Brief Summary

Overcrowding in the emergency department is an increasing problem in hospitals worldwide. Point-of-care Troponin (POC cTn) testing combined with a well investigated risk stratification tool (HEART-score) used in the ambulance may contribute to more rapidly diagnostics of ruling in or ruling out myocardial infarctions (MI) and subsequently reduce unnecessary hospital admissions, total admission time and costs. However, the applicability of the POC cTn and the HEART-score in the pre-hospital setting remains unclear. This study will evaluate this applicability.

Outcome Measures

Primary Outcomes (3)

  • Heart score agreement

    HEART-score agreement (interobserver variability between pre-hospital and in-hospital HEART-score assessment): the calculated heart score by the ambulance will be subtracted from the calculated score of the emergency department. The minimum value could be -10 and the maximum value could be +10. A positive score means that the ambulance estimates the patient to be sicker or at higher risk. A negative value means that the ED estimates the patient to be sicker/at higher risk for developing major adverse cardiac events.

Study Arms (1)

Possible NSTE-ACS

All patients with a suspicion of non-ST-elevation acute coronary syndrome (NSTE-ACS) in the pre-hospital phase are eligible for inclusion. In all included patients, the POC cTn will be performed and the HEART-score will be calculated in the pre-hospital phase. Simultaneously, a venous blood sample will be drawn from the venous access site for later hs-cTn testing. Outcomes of both the POC cTn or the pre-hospital HEART-score will be blinded for the physicians at the emergency department (ED) and will not affect current treatment strategy. All patients with suspected NSTE-ACS will undergo hs-cTn testing and the HEART-score will also be calculated at the ED (T1, standard of care). Here, an additional venous blood sample will be drawn next to routine blood testing testing (T1).

Device: Possible NSTE-ACS

Biospecimen

Retention: SAMPLES WITH DNA

two venous blood samples will be drawn in the pre-hospital phase. One will be used for high-sensitive troponin measure in the pre-hospital phase (at the resident of the patient). The second one will be used to validate the point-of-care measurement with the troponin value in the laboratory.
