ABSTRACT: Background
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.
