Prognostic difference between walk-in and ambulance-transported patients with ST elevation myocardial infarction from Mie ACS Registry

Abstract Background The prognostic impact of walk-in patients with ST elevated myocardial infarction (STEMI) is unknown. aim this study was to compare the prognosis STEMI and ambulance-transported patients. Methods We evaluated 260 1,641 enrolled from Mie ACS registry, which a prospective multicenter registry between 2013 2019. Propensity score matched analysis performed validate results. Coronary risk factor, sex, Killip class, door-to-balloon time used for compute propensity score. Results matching yielded 226 cases per group. All-cause mortality tended be higher in group than without reaching significant difference, although had slightly before (See Figure 1). Symptom-onset-to-reperfusion significantly longer (241 vs 184 minutes, p<0.01). Conclusion short mid-term similar However, prehospital delay should shortened by using ambulance better Funding Acknowledgement Type funding sources: None.
