Inpatient-Onset Versus Outpatient-Onset ST-Segment-Elevation Myocardial Infarction in Patients With Percutaneous Coronary Intervention: A National Registry Study.

ABSTRACT:

Background

Compared with patients who develop ST-segment-elevation myocardial infarction (STEMI) outside the hospital and present at the emergency department (outpatient-onset), patients with inpatient-onset STEMI may paradoxically experience a poorer prognosis due to underlying disease, despite the apparent immediate access to acute health care services.

Methods

Patients with first-onset STEMI who underwent percutaneous coronary intervention (PCI) in the Singapore Myocardial Infarction Registry (2007-2020) were included. For patients with inpatient-onset STEMI, the recognition-to-balloon time was measured from symptom onset to PCI. For outpatient-onset STEMI, the recognition-to-balloon time was defined as the sum of the symptom-to-door and door-to-balloon time. Logistic reg
