Figure 1. Estimated yearly incidence of acute myocardial infarction (AMI), non–ST‐segment–elevation myocardial infarction (NSTEMI), and ST‐segment–elevation myocardial infarction (STEMI).

Our findings corroborate those of prior epidemiologic studies, demonstrating that the overall incidence of emergency department (ED) visits for AMI and STEMI have declined, while ED NSTEMI diagnoses have increased, albeit to a lesser degree.
