Coronary disease & ACSCohort study

Specificity of the Occlusion Myocardial Infarction-Trained PMcardio “Queen of Hearts” AI-ECG in Inflammatory Myopericardial Syndromes

JACC AdvPublished

  • single-centre retrospective study
  • consecutive emergency department patients

Authors' conclusion

In IMPS, the OMI-trained QoH model demonstrated high specificity and fewer false-positive OMI classifications than guideline ECG-STEMI criteria, ECG-based scores, and general-purpose LLMs.

Study context

Population
Emergency department patients with adjudicated inflammatory myopericardial syndromes (IMPS), obstructive coronary artery disease excluded, University & Hospital of Fribourg (2010–2025)
Participants
242 IMPS patients
Exposure
Specificity was compared with European Society of Cardiology (ESC) STEMI ECG criteria, the 4-variable formula (when applicable), and 3 large language models
  • 4-variable formulan = 30
Outcome
ECG-level specificity
