Abstract:
Prior studies have described racial/ethnic disparities in door‐to‐balloon ( DTB ) time for patients undergoing primary percutaneous coronary intervention ( PCI ). We sought to compare DTB time between different racial/ethnic groups undergoing primary PCI for ST ‐elevation myocardial infarction in Get With the Guidelines ( GWTG ). Hypothesis There may be differences in D2B time associated with race/ethnicity. Methods We identified 7445 white (n = 6365), African American (n = 568), and Hispanic (n = 512) patients undergoing primary PCI . Results There were no differences in the median DTB time between white (74 minutes; intraquartile range [ IQR ], 54–99), African American (77 minutes; IQR , 57–100), and Hispanic (75 minutes; IQR , 56–100) ( P = 0.13) patients. There were no crude differences in DTB time ≤90 minutes; however, after adjusting for confounders, African American race was associated with lower odds of DTB time ≤90 minutes (odds ratio [ OR ]: 0.84; 95% confidence interval [ CI ]: 0.70‐0.99; P = 0.04). This association was seen in African American males ( OR : 0.66; 95% CI : 0.55‐0.80) but not African American females ( OR : 1.27; 95% CI : 0.96‐1.68). Overall, Hispanic ethnicity was not associated with a difference in DTB time ≤90 minutes ( OR : 0.98; 95% CI : 0.77‐1.25; P = 0.88); although Hispanic males did have a slightly longer median DTB time compared with whites. During the study, the proportion of patients with DTB times ≤90 minutes increased for all groups, and mortality was similar between groups (white 3.8%, African American 3.0%, Hispanic 4.1%, P = 0.62). Conclusions In GWTG ‐Coronary Artery Disease, small differences in DTB times persist among different races/ethnicities. However, the proportion achieving DTB times ≤90 minutes has increased substantially for all patients over time, and there was no association between race/ethnicity and in‐hospital mortality.
