Effect of prehospital 12-Lead electrocardiography on the emergent medical system for ST-Segment–Elevation myocardial infarction during the coronavirus disease 2019 (COVID-19) pandemic: results from the K-ACTIVE registry

Key Points

• Prehospital 12-lead electrocardiography significantly improves outcomes for ST-segment-elevation myocardial infarction during the COVID-19 pandemic.
• Findings indicate faster treatment initiation leads to better clinical results, emphasized through dataset analysis.
• The study employed observational analysis across emergency medical systems involved in the K-ACTIVE registry.
• These results imply potential enhancements to emergency response protocols in future public health crises.
