Limited information exists about characteristics of patients with acute myocardial infarction (AMI) in Asia. We examined trends in interventional treatment and clinical outcomes for AMI from the Korea Acute Myocardial Infarction Registry (KAMIR). The study population was derived from patients in the KAMIR from November 2005 to December 2016. We identified 54,402 patients with ST-elevation myocardial infarction (STEMI) (n = 29,222) and non-ST-elevation myocardial infarction (NSTEMI) (n = 25,180). The rate of percutaneous coronary intervention (PCI) increased to 96.2% of STEMI group and 84.3% of NSTEMI group in 2016, respectively (All p_trend <0.001). Furthermore, the rate of successful PCI was 97.3% in STEMI and 97.9% in NSTEMI. The rate of primary PCI increased from 67.8% in 2005 to 96.9% in 2016 (p_trend <0.001). Moreover, in patients with STEMI, the proportion of drug-eluting stent …
