Effect of Race and Ethnicity on Outcomes With Drug-Eluting and Bare Metal Stents
Why the study?
Does the use of drug-eluting stents improve long-term outcomes compared to bare metal stents across different racial and ethnic groups in older patients undergoing percutaneous coronary intervention?
Population
423,965 patients > 65 years of age undergoing stent implantation from 2004 through 2008
Comparison
Drug-eluting stents (DES) vs Bare metal stents (BMS)
Design
Cohort
Follow-up
30 months

Implication
Disparities in post-PCI death and MI persist among black and Hispanic patients; cohort data leave open uniform DES benefit.

Population
423,965 patients > 65 years of age undergoing stent implantation from 2004 through 2008 (390,351 white, 20,191 black, 9,342 Hispanic, and 4,171 Asian patients)

Comparator
Bare metal stents (BMS)
O
Outcome
30-month death and myocardial infarctionhard clinical
Black and Hispanic patients undergoing PCI have worse long-term outcomes compared to white and Asian patients, and while DES generally provides superior outcomes to BMS, this benefit was not statistically significant in Hispanic patients.
