Ambulance algorithm aims to speed up heart attack diagnosis
NCT ID NCT07419139
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new algorithm that helps paramedics decide if a patient with chest pain is having a heart attack. About 304 patients will get a quick blood test in the ambulance, and researchers will track their outcomes for 90 days. The goal is to fine-tune the algorithm for future use, not to change current care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a more accurate way for paramedics to decide which patients need immediate hospital care for a heart attack.
- What could go wrong
- This is an early calibration study, not a treatment trial. The algorithm may not prove accurate enough in real-world use, and results may not apply to all regions or populations.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study population includes adult patients with suspected myocardial infarction who are attended by emergency medical services (EMS). Eligible participants must have symptom onset more than 30 minutes before EMS arrival and be able to provide written informed consent. Patients will be excluded if they present with ST-elevation myocardial infarction (STEMI) on the initial ECG, unstable angina, hemodynamic instability, life-threatening arrhythmias, or cardiac arrest. Additional exclusion criteria include non-ischemic conditions requiring hospital admission, EMS deployment requested by a primary care physician, and age under 18 years.
