About this study
With the Emergency Medical Services (EMS), no prehospital risk stratification and triage is performed for patients suspected of having an Non-ST-segment elevation Acute Coronary Syndrome (NSTE-ACS). While the latest ESC Guidelines recommend an early invasive strategy within 24 hours for all high risk NSTE-ACS patients and same-day transfer to a PCI (Percutaneous Coronary Intervention) center. With the potential emerging logistical problem surrounding this, prehospital risk stratification and triage can have great benefits in this population as well, especially in patients with a high risk of having an NSTE-ACS. The recently validated PreHEART score makes it possible to stratify patients in a low-risk and high-risk group for having a NSTE-ACS and gives the EMS the opportunity to make triage decisions in the prehospital setting. Patients with a high risk for having an NSTE-ACS are transferred directly to an PCI-center for further diagnostic work-up. Patients with a low risk for having NSTE-ACS and transferred to the ED of the nearest hospital without PCI facilities (non-PCI center) for further diagnostic work-up, resulting in an optimization of the regional care utilization.
This is the first study to focus on patients who are at a high risk of having an NSTE-ACS and to assess if whether prehospital triage using the PreHEART score is able to significantly reduce time to final invasive diagnostics and revascularization in patients in need of coronary revascularization.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PreHEARTDiagnostic test
The PreHEART score is validated for use in the pre-hospital setting.The score can be calculated based on five different elements: history, ECG, age, gender, and a Point-of-Care (POC)-Troponin. A minimum of 0 points and a maximum of 2 points can be scored in each element, the total PreHEART can contain a maximum of 10 points. The score of the history is based on the symptoms of the patient in accordance with the symptoms of a myocardial infarction. Based on the suspicion of ischemia on the ECG. Age will be based on the date of birth. Compared to the female gender, the male gender has higher risk of developing myocardial infarction and will be scored higher. The biomarker Troponin will be collected via intravenous access and measured using a POC-analyzer "I-Stat" from Abbott industries. In total 17 µl of blood is required to fill a cardiac Troponin I (cTnI) cartridge. Analyzing the blood will take approximately 10 minutes.
| Study group | Role | What they receive |
|---|---|---|
| Cohort 1 (reference group) | 500 patients will be included as an observatory control group and as a reference group to the second cohort. The PreHEART score is calculated without further consequences for triage in the ambulance and are transferred to the ED of the nearest hospital for standard care. | |
| Cohort 2 (intervention group) | 500 patients will be included in the interventional cohort. The calculated PreHEART score has consequences for triage in the ambulance. If the PreHEART score is ≥ 5, the patient is classified as a high-risk patient for having NSTE-ACS. These patients are immediately transferred to the ED of the nearest PCI center for further diagnostic examination and to rule out other life-threatening pathologies. When the PreHEART score is ≤ 4, the patient is classified as a low-risk patient for having NSTE-ACS and is transferred to the ED of the nearest hospital without PCI facilities (non-PCI center) for further diagnostic work-up Receives: Diagnostic Test: PreHEART |

Questions about this trial
What is this clinical trial studying?
An observational study of ACS and NSTEMI - Non-ST Segment Elevation MI, run by Catharina Ziekenhuis Eindhoven at 1 site in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Time from first medical contact to final invasive diagnostics and revascularization (time frame: Time from first medical contact by EMS to final invasive diagnostics and revascularization, up to 60 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05243485, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Feb 2024.
