We have previously reported the advantages of a prehospital 12-lead electrocardiography system (P-ECG) for ST-segment elevation myocardial infarction (STEMI) patients (Circ Rep 2019; Circ J 2022, 2023). Since 2020 with Coronavirus disease 2019 (COVID-19), patient transport situation has changed dramatically. investigated how was by COVID-19. The effect (ECG) also evaluated. Recent urban STEMI who received primary percutaneous coronary intervention (PCI) using P-ECG were assigned to group (n=87; age 69±14 years), and comparable not Conventional 71±13 years). pre-COVID-19 period is defined as before pandemic began, COVID-19 time thereafter. In group, first medical contact (FMC)-to-reperfusion (110±45 vs. 90±31 min; P=0.025) door-to-reperfusion (89±41 70±29 P=0.015) in significantly longer than period. However, there no difference FMC-to-reperfusion between 2 periods. Killip class (2.0±1.3 1.1±0.5; P=0.001) left ventricular ejection fraction (49±12 57±9.0%; P=0.002) poorer significant During pandemic, might provided outcomes patients.
