Over the past decade, rates of acute myocardial infarction (AMI) hospitalizations for older Medicare patients have decreased. This article examines the trends in recent decreases across age, gender, and ethnicity categories.
Using discharges from hospitals in the National Inpatient Sample (NIS) from the Healthcare Cost and Utilization Project (HCUP) between 2001 and 2007, the study included 2,179,509 AMI hospitalizations. The 2000 Census data with annual intercensal survey adjustments were used to calculate population-based overall and AMI rates.
Overall, despite a decreased rate of AMI hospitalizations overall, across all age groups studied, the observed decrease was less for Black patients compared to White patients.
