The main outcome was patient-related delay defined as the time from symptom onset to first medical contact (FMC). In patients who presented through EMS, FMC was considered the time of receiving the call to exclude EMS-related delay. Other in-hospital outcomes included door-to-balloon time, cardiac troponin (cTn-I) level on admission, recurrent angina, acute decompensated heart failure (NYHA class III or IV), cardiogenic shock, significant arrhythmias, or mechanical complications (eg, ventricular septal rupture, ischemic mitral regurgitation, etc). The study was approved by our local institutional audit and quality improvement committees. Informed consents were waived because of the nature of the study.
