Brief summary
AI ECG TIMI is an investigator-initiated, international, and multicenter registry of acute coronary syndrome patients aimed to identify electrocardiographic findings detected by an AI model predicting coronary blood flow alteration. The aim of the study is to identify electrocardiographic findings detected by an automated artificial intelligence (AI) model that can predict coronary blood flow alteration as assessed by the TIMI grade flow at the very moment of the invasive coronary angiography in patients with acute coronary syndromes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Diagnostic Accuracy of the AI-ECG TIMI AI Model | Index hospitalization (assessed up to 5 days) | The primary endpoint is the AI-ECG TIMI model's ability to identify patients with actively occluded (TIMI 0-1) at the time of invasive coronary angiography using only single-standard 12-lead ECGs assessed by accuracy, sensitivity, specificity, positive, negative predictive values and F1 scores. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Subgroup Performance | Index hospitalization (assessed up to 5 days) | AI-ECG TIMI AI Model's performance across subgroups 1. Demographic 2. Risk factors \& co-morbidities 3. Electrocardiographic 4. Culprit artery territory |

| Subgroup analysis of NSTEMI-OMI patients | Index hospitalization (assessed up to 5 days) | 9\. NSTEMI-OMI stratified according to immediate (\<2h) vs. SoC (\>2h) invasive management, median: i. Peak troponin (maximum rise before fall) ii. Median LVEF at discharge iii. Length of hospital stay iv. Length of cardiac care unit (CCU) or intensive care unit (ICU) stay v. Presence of life-threatening arrhythmias |
