Abstract P93: Differences in Practice Patterns and Outcomes Between Hispanics and Non-Hispanic Whites Treated for ST-Segment Elevation Myocardial Infarction: Results From ACTION Registry - Get With the Guidelines

Background: Ethnic differences have been reported in the treatment and outcomes of patients with non-ST-segment elevation myocardial infarction (non-STEMI). Potential ethnic disparities in contemporary STEMI management have not been well characterized. Methods: We compared practice patterns and outcomes between 1,654 Hispanics (H) (4.1%) and 38,844 non-Hispanic Whites (NHW) treated for STEMI in ACTION Registry-GWTG between 01-2007 and 03-2009. Logistic generalized estimating equation modeling was used to examine associated risk-adjusted mortality. Results: Hispanic patients more frequently had diabetes (32% vs 21%, p Conclusions: Despite similar in-hospital mortality, Hispanic STEMI patients had significant differences in process of care with longer triage and treatment delays than non-Hispanic Whites. As the fastest growing minority in the United States, this population needs further efforts to optimize their care processes Hispanics Non-Hispanic Whites p value Ambulance use 41.5% 47.0% Pre-Hospital EKG 32.8% 37.5% Onset of pain to arrival (median) 2.0 hrs 1.6 hrs Arrival to EKG (median) 8 min 6 min Arrival to EKG 61.2% 69.3% Reperfusion therapy 91.6% 93.1% 0.04 Arrival to PCI (median) 74 min 69 min DTB 69.4% 77.5%
