Trends are expressed as adjusted odds ratios (95% confidence intervals) for each year relative to 2003. Regression model adjusted for demographics (except sex and race/ethnicity for sex‐ and race/ethnicity‐specific trends, respectively), hospital characteristics, all comorbidities, and presentation. IABP indicates intra‐aortic balloon pump; STEMI, ST‐elevation myocardial infarction.
