Registered outcomes6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Diagnostic accuracy of the AI-ECG model for angiographically confirmed occlusion myocardial infarction | From triage ECG to 7 and 30 days after index presentation | Sensitivity, specificity, positive predictive value, negative predictive value, overall accuracy and area under the receiver-operating characteristic curve of the AI model's verdict on the first 12-lead ECG recorded at triage, against the pre-specified composite reference standard for OMI. The decision threshold is fixed a priori at the manufacturer's on-label cut-off; no threshold optimisation is performed. |
| Secondary | Comparative diagnostic accuracy versus formal STEMI criteria | From triage ECG to 7 and 30 days after index presentation | Compared with the full ECG criteria for myocardial ischaemia and infarction under the Fifth UDMI (2026): the thresholds in 2a, plus new horizontal or down-sloping ST-segment depression ≥0.5 mm at the J-point in two or more contiguous leads; T-wave inversion \>1 mm in two contiguous leads; posterior infarction patterns (ST-depression ≥1 mm in V1-V3, particularly with dominant R wave, confirmed by ST-elevation in V7-V9); right ventricular infarction (ST-elevation in V3R-V6R); the Aslanger pattern; the South African flag sign; and modified Sgarbossa criteria in LBBB and ventricular pacing. Applied by a blinded reviewer. |
| Secondary | Versus conventional ST-elevation millimetre criteria | From triage ECG to 7 and 30 days after index presentation | Compared with ST-elevation at the J-point in two contiguous leads: ≥1 mm in all leads other than V2-V3; in V2-V3, ≥2 mm in men ≥40 years, ≥2.5 mm in men \<40 years, ≥1.5 mm in women. Applied by a blinded reviewer. Retained because it corresponds to the criteria used in the prior validation literature and permits direct comparison with those cohorts. |
| Other | Proportion of triage ECG recordings successfully linked to the patient record | During the index ED visit, over the 12-month recruitment period | Proportion of 12-lead ECGs recorded at triage that are successfully linked to the correct patient encounter using barcode scanning of the patient wristband label, with the denominator being all triage ECGs recorded in patients presenting with chest pain. |
| Other | Diagnostic accuracy of AI-based ECG analysis in pre-specified patient subgroups | Through 30 days after the index ED visit | Sensitivity, specificity and AUROC with 95% confidence intervals, calculated separately within pre-specified subgroups: sex; age category (\<65, 65-79, 80 years and over); estimated glomerular filtration rate (\<60 vs 60 mL/min/1.73 m² and above); Manchester triage acuity category; reported duration of symptoms; and mode of arrival (ambulance vs self-presentation). These analyses are exploratory and hypothesis-generating; no formal adjustment for multiple comparisons is planned, and differences between subgroups will be interpreted descriptively. |
| Other | Proportion of enrolled patients for whom an initial high-sensitivity troponin result is retrievable, stratified by care pathway and by triage stream. Reported with reasons for non-retrievability | Index hospitalisation, up to 5 days | Proportion of enrolled patients for whom an initial high-sensitivity troponin result is retrievable, stratified by care pathway and by triage stream. Reported with reasons for non-retrievability. This quantifies the data-linkage limitation. |
