Impact of race and ethnicity on inhospital outcomes after percutaneous coronary intervention (report from the 2000-2001 New York State Angioplasty Registry)

Background

Studies regarding the impact of race and ethnicity on outcomes after percutaneous coronary intervention (PCI) in the modern era are limited.

Methods

Using the 2000 and 2001 New York State PCI Databases, we compared baseline clinical, demographic, and angiographic characteristics and subsequent inhospital events among 76928 patients of black, Hispanic, and white racial/ethnic backgrounds. We sought to determine the influence of race and ethnicity, if any, on post-PCI outcomes.

Results

Blacks and Hispanics were younger and more likely to be hypertensive, diabetic, obese, in congestive heart failure, and have chronic renal insufficiency. Whites were more likely to be men, have multivessel disease, and receive a stent. There was no significant difference in unadjusted post-PCI inhospital mortality (0.7% for all groups) or major adverse cardiac event (defined as death, emergent coronary bypass, or stroke) among all 3 racial groups. After correcting for clinical and demographic variables, race/ethnicity was not a significant predictor of death or major adverse cardiac event.

Conclusion

Minority patients of black and Hispanic decent have a significantly higher incidence of traditional cardiovascular risk factors and present for angioplasty at a younger age compared with whites. However, there is no significant difference in outcomes after angioplasty among these racial/ethnic groups.
