Cardiovascular disease remains the most common cause of morbidity and mortality in the United States, and each year an estimated 785 000 US residents will have a new myocardial infarction (MI), and approximately 470 000 will have a recurrent MI.1 ST-segment elevation myocardial infarction (STEMI) constitutes a subset of MI presentation, defined by characteristic symptoms of myocardial ischemia and associated with ST-segment elevation or new or presumed new left bundle-branch block. Among patients presenting with an MI, the percentage of cases with STEMI varies in different registries and databases. According to the National Registry of Myocardial Infarction 4 (NRMI-4), among all patients with MI, approximately 29% present with STEMI.2
