Deep learning electrocardiogram model for risk stratification of coronary revascularization need in the emergency department
Authors' conclusion
The model was able to detect revascularization and Type 1 MI with competitive performance, suggesting a potential role to complement current clinical assessment.
Study context
- Population
- ED visits; US cohort (training/test) and European external validation cohorttest n = 35,995
- Comparison
- Deep learning electrocardiogram (ECG) model vs clinician ECG interpretation and cardiac troponin T
- Outcome
- AUROC for coronary revascularization
Methodological detailsexternal validation, Trained on 144 691 US ED visits
- External validation
- Trained on 144 691 US ED visits

External validation (Europe, n = 18 673)
- ECG model had higher specificity but lower sensitivity vs hs-TnT
