Effect of the new diagnostic criteria for ST-elevation and non-ST-elevation acute myocardial infarction on 4-year hospitalization: an analysis of hospital discharge records in the Veneto Region

Abstract

Despite some limitations, our results indicate that the new diagnostic criteria for acute myocardial infarction have a major impact on epidemiological evaluation. These data may be relevant when comparing epidemiological data of different periods and planning healthcare policies. Further studies are needed in order to evaluate the accuracy of ICD-9-CM codes in the diagnosis of ACSs.
