Temporal changes in patient characteristics and outcomes in ST‐segment elevation myocardial infarction 2003–2018

Background We sought to describe changes in demographic variables, process of care measures, and outcomes of patients treated in a regional ST‐segment elevation myocardial infarction (STEMI) program over the last 15 years. Methods We describe demographic variables, process of care measures, and outcomes of patients treated in the program in various 5‐year time periods: 2003–2007 (n = 1,821), 2008–2012 (n = 1,968), and 2013–2018 (n = 2,223). The primary outcome measures were in‐hospital and 30‐day mortality. Results Among 6,012 STEMI patients treated from 2003 to 2018 we observed a significant increase in mean age at presentation (62 ± 14 to 64 ± 13 years) and diabetes (14–22%, p
