Queen of Hearts AI model outperforms standard care in detecting severe heart attacks from ECGs.
Key Details
- 1Queen of Hearts, part of PMcardio, evaluates 12-lead ECGs for STEMI detection.
- 2Study included over 1,000 suspected STEMI patients treated from Jan 2020 to May 2024 across three PCI centers.
- 3STEMI confirmed in 58.2% of cases; 41.8% were false positives by standard care.
- 4AI model improved sensitivity (92% vs. 71%) and specificity (81% vs. 29%) compared to standard triage.
- 5False positives were greatly reduced (7.9% vs. 41.8%); area under ROC curve was 0.94.
- 6The model correctly reclassified 91% of false alerts identified by standard care.
Why It Matters
This validation highlights AI's transformative potential in acute cardiovascular diagnostics, offering more accurate triage, reducing unnecessary emergency interventions, and improving outcomes for patients with suspected heart attacks.
