Abstract 2474: Post-Procedural Outcomes in Hispanics, Asians, American Indians, and Caucasians Following Percutaneous Coronary Intervention
Background: Although there are data comparing the post-PCI outcomes in African American and Caucasians, there is little data regarding outcomes in non-African American minority racial groups undergoing PCI. We hypothesized that significant differences in post-PCI outcomes would be present among races.
Methods: We analyzed 641,186 PCIs within the American College of Cardiology National Cardiovascular Data Registry from 1/1/2001 to 12/31/2004. Baseline characteristics and in-hospital post-PCI outcomes (death, MI, unplanned CABG, major bleeding, and stroke) in Hispanics (HA; n=13,914), Asians (AA; n=6,548), and American Indians (AI; n=1,875) were compared to Caucasians (CA; n=618,849).
Results: Several differences in baseline clinical characteristics and coronary angiographic findings among the racial groups were present. Unadjusted in-hospital mortality rates were higher in AA (1.6%; p<0.01) and HA (1.5%; p<0.05) compared to CA (1.2%). After adjustment using a validated mortality risk model, no significant differences in mortality rates were observed in HA (1.35%; 95% CI 1.25–1.44%), AA (1.28%; 95%CI 1.14 –1.43), AI (1.08%; 95%CI 0.81–1.34) compared to CA (1.26%; 95%CI 1.24 –1.28). Other adjusted post-PCI outcomes are shown below.
Conclusion: No differences in adjusted in-hospital mortality after PCI were observed in HA, AA, and AI compared to CA. However, post-PCI complications such as MI, unplanned CABG, and major bleeding differences existed among racial groups. Targeted research is needed to understand why racial minorities have more post-PCI complications such that specific interventions can be implemented to potentially reduce complication rates.
