Factors Associated With Ineligibility for PCI Differ Between Inpatient and Outpatient ST-Elevation Myocardial Infarction

Objectives Without early revascularization, both inpatient and outpatient STEMIs have poor outcomes. Reasons for denying PCI for STEMI, however, remain uncertain. This single‐center retrospective cohort study compares factors and outcomes associated with ineligibility for PCI between inpatients and outpatients following ST‐elevation myocardial infarction (STEMI). Methods A total of 1,759 STEMI patients between June 2009 and January 2015 were assessed. Individual medical records were reviewed to obtain reasons for PCI ineligibility for STEMI patients who did not receive reperfusion therapy. Results Compared to outpatients with STEMI (n = 1,688), inpatients (n = 71) were less likely to receive coronary angiography (60.6% vs 95.9%; P
