Background:
The difference of mortality risk between ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) has not been thoroughly evaluated yet. We sought to compare clinical outcomes of ST-segment Elevation Myocardial Infarction and Non-ST-segment Elevation Myocardial Infarction over 1-years follow-up using Korean Registry of Regional Cardiocerebrovascular center for Acute Myocardial Infarction (KRAMI).
Methods:
From the Korean Registry of Regional Cardiocerebrovascular center for Acute Myocardial Infarction (July 2016 - Sept 2018), patients over 18 years old who underwent acute myocardial infarction were selected. We included patients who had STEMI and NSTEMI and excluded in-hospital mortality. We compared in-hospital death and long-term (within 1-year) mortality, composite in NSTEMI patients with those in STEMI patients. 
Results:
From July 2016 through Sept 2018, a total of 8,733 patients were enrolled at the KRAMI: 3,839 enrolled in the STEMI patients and 4,894 enrolled in the NSTEMI patients. The STEMI patients, as compared with NSTEMI patients, was difference in in-hospital death (HR=11594[1.310-1.939], p=0.000), in 1year composite(HR=0.748[0.570-0.981], p=0.000). (Table 1).

Conclusion:
The short-term all-cause death events in patients with STEMI were significantly higher than NSTEMI, but the long-term composite events in patients with NSTEMI were significantly higher than STEMI.
