摘要
Pprimary percutaneous coronary intervention （PPCI） is the cornerstone of treatment to reduce infarct size andimprove outcomes in patients with ST-elevation myocardial infarction （STEMI）.1 The optimal site for initiation of reperfusion strategies is the patient＇s home or place where the infarction occurs. In PPCI, direct catheterization lab notification from the ambulance leads to shorter first medical contact to balloon time by bypassing emergency departments.2 The current guidelines recommend that STEMI patients undergo PPCI with a balloon inflation time within 90 minutes of first medical contact.3 However, most STEMI patients require transfer to percutaneous coronary intervention （PCI） -capable hospitals, but timely transfer has been shown to occur in a minority of patients. For example,
