Approximately 1.5 million cases of myocardial infarction (MI) occur annually in the United States; the yearly incidence rate is approximately 600 cases per 100,000 people. The proportion of patients diagnosed with non–ST-elevation MI (NSTEMI) compared with ST-elevation MI (STEMI) has progressively increased. Despite an impressive decline in age-adjusted death rates attributable to acute MI since the mid-1970s, the total number of MI-related deaths in the United States has not declined. [26]
