Coronary heart disease is disproportionately prevalent in the American Indian/Alaska Native (AI/AN) population. As care for acute myocardial infarction (AMI) continues to advance, equitable distribution and access for the AI/AN population is essential. Primary AMI hospitalizations for adults ≥18 years of age were identified from the Healthcare Cost and Utilization Project National Inpatient Sample from 2000 to 2018. Related co-morbidities, procedures of interest, and in-hospital mortality were also identified. These rates were stratified by race then trended over years using Poisson regression. Overall, 9,904,714 weighted hospitalizations for primary AMI were identified. From 2000 to 2018, AI/AN adults had relatively high rates of primary AMI hospitalization, second only to non-Hispanic (NH) White adults. The AMI rate increased from 14.0/1,000 to 16.1/1,000 among AI/AN adults, remaining higher than NH Black adults (12.1/1,000 to 13.0/1,000) and Hispanic adults (10.3/1,000 and 12.7/1,000) and becoming increasingly closer to NH White adults (25.1/1,000 to 20.0/1,000) (p
