BACKGROUND: Racial differences in reperfusion therapy use among patients hospitalized with myocardial infarction (MI) have been previously reported as national phenomenon. However, it is unclear whether racial differences in treatment vary by region. METHODS: Using data from the National Registry of Myocardial Infarction-2 and -3, a cohort of patients hospitalized with MI in the United States between 1994 and 2000, we sought to determine whether racial differences in reperfusion therapy use varied by geographic region in patients eligible for reperfusion therapy with no clinical contraindications to treatment (n = 204 230). RESULTS: Black patients had lower crude rates of reperfusion therapy than white patients (66.5% vs 69.9%, -3.3% racial difference, 99% CI -4.4% to -2.2%) overall. However, racial differences in reperfusion therapy use varied by geographic region. Reperfusion therapy rates were similar for black patients and white patients in the Northeast (67.9% black vs 65.3% white, +2.7% racial difference, 99% CI -0.5% to 5.8%) and statistically comparable for patients in the Midwest (68.3% black vs 69.0% white, -0.7% racial difference, 99% CI -2.9% to 1.5%) and West (70.7% black vs 72.6% white, -1.9% racial difference, 99% CI -5.1% to 1.2%). Racial differences in reperfusion therapy use were greatest for patients hospitalized in the South (64.5% black vs 71.7% white, -7.1% racial difference, 99% CI -8.7% to -5.6%). Racial differences were reduced, but geographic variations in racial differences persisted after multivariable adjustment. CONCLUSIONS: Lower rates of reperfusion therapy use among black patients with MI do not reflect a national pattern of racial differences in treatment, but a practice pattern predominantly attributable to the South.
