Trends in Incidence of Hospitalized Acute Myocardial Infarction in the Cardiovascular Research Network (CVRN)

Among a large, diverse, multicenter community-based insured population, there were significant decreases in incidence of hospitalized acute myocardial infarction and the more serious ST-segment elevation myocardial infarctions between 2000 and 2008. Decreases in ST-segment elevation myocardial infarctions were most pronounced among women. While ecologic in nature, these secular decreases likely reflect, at least in part, results of improvement in primary prevention efforts.
