Go to the Emergency Department　― Early Cardiologist Engagement in Acute Myocardial Infarction Complicated by Cardiogenic Shock ―

Association guidelines 3 recommend an FMC2D <90 min.The 2023 European Society of Cardiology guideline 4 further recommends a target of min when ST-elevation is identified by an emergency medical service (EMS) or at a non-PCI-capable hospital and min identified at a PCI-capable hospital.Furthermore, EMS-obtained prehospital ECGs are effective for the early recognition and triage of STEMI. 5These ECGs enable direct transport to PCI-capable hospitals, facilitate early activation of the catheterization team, and may allow T o achieve early reperfusion in patients with STelevation myocardial infarction (STEMI), several time-based metrics have been introduced to reduce the total myocardial ischemic time from symptom onset to reperfusion.Among these, the door-to-device interval has served as an indicator of time efficiency of percutaneous coronary intervention (PCI)-capable hospitals in STEMI treatment, with prior studies reporting progressive improvements. 1Additionally, the first medical contact-to-device interval (FMC2D) has been recognized as a more comprehensive metric reflecting regional coordination across prehospital and in-hospital systems.
