Abstract
The superiority of drug-eluting stents (DES) compared with bare-metal stents (BMS) is well-established, but data regarding DES use in ST-elevation myocardial infarction (STEMI) as a function of race is limited. Our goal was to examine stent utilization patterns and disparities based on race, sex, and insurance status in patients with STEMI undergoing percutaneous coronary intervention. The National Inpatient Sample database was used to retrospectively compare DES vs BMS use in patients admitted with STEMI from 2009 to 2018. Multivariable logistic regression was performed to assess the independent predictors of DES use. DES utilization increased significantly from 62.8% in 2009 to 94.0% in 2018. However, African Americans were less likely to receive a DES (odds ratio [OR] .82, 95% confidence interval [CI] .77–.87) compared with Caucasians. Women were more likely to undergo DES implantation (OR 1.07, 95% CI 1.05–1.10). Patients insured by Medicaid (OR .84, 95% CI .80–.89) and those classified as Self-pay (OR .63, 95% CI .61–.66) were less likely to undergo DES implantation compared to those with private insurance (OR 1.33, 95% CI 1.29–1.38). Disparities based on race and insurance status continue to persist despite a significant increase in DES utilization in STEMI patients across the identified subgroups.
