Abstract Body (Do not enter title and authors here): Introduction: ST elevation myocardial infarction (STEMI) is associated with a persistent high global mortality rate. Early diagnosis and treatment are essential to improve cardiac outcomes. Wearables may play a key role as promising technology in this clinical scenario.
Methods: 70 consecutive patients were referred to coronary angiography (cath) due to typical chest pain and STEMI standard 12-lead ECG tracing. At cathlab, 4-electrodes-12-leads-wearable-smartphone-based-ECG-System(AngelUS®) tracing was performed. ECG tracings interpretations were compared between the 2 groups by independent cardiologists blinded to ECGs and then correlated with cath findings. The Cohen κ statistic was used to measure agreement between the 2 groups.
Results: Both cardiologists agreed to include 70 standard ECG tracing and 70 AngelUS® ECG tracing as STEMI. Both cardiologists agreed to exclude 70 standard ECG tracing and 70 AngelUS® ECG tracing as absence of STEMI, showing a perfect agreement with Cohen’s k:1. Correlations with coronary angiography were also performed showing total agreement with both ECG diagnostics.
Conclusion: In 70 consecutive patients with typical symptoms and STEMI, standard ECG and the AngelUS®4-Electrodes-12-Leads-Wearable-Smartphone-Based-ECG showed clinical agreement. Correlations with coronary angiography were also performed, showing clinical equivalence between both ECG diagnostics. Analysis of AngelUS® ECG tracing compared to standard ECG is ongoing, extending our investigation into the utility of this technology in preoperative ECGs.
