Abstract
BACKGROUND/ PURPOSE: Women are underrepresented in cardiovascular clinical studies. Black women have a higher ischemic heart disease mortality risk than their white counterparts. However, there exist limited outcome data comparing black women and white women after percutaneous coronary intervention (PCI). The aim of this retrospective analysis was to evaluate for racial disparities in 1-year major adverse cardiovascular events (MACE) in women undergoing PCI. METHODS/MATERIALS: Within our PCI database, we identified 4776 female patients who underwent PCI between 2003 and 2016. Of those, 1916 were black and 2860 were white. Endpoints included MACE, death, myocardial infarction, target vessel revascularization (TVR) and stent thrombosis (ST) at 30 days and 1 year. A proportional Cox hazard model analysis was performed to assess outcomes after adjustment for confounding factors. RESULTS: Black women presented at a younger age and had a significantly higher prevalence of risk factors. Periprocedural and in-hospital outcomes were similar in the 2 groups. At 30 days and 1 year, the rates of myocardial infarction, TVR and ST were significantly higher in black women. After adjustment for baseline differences, only ST appears to be more likely to occur in black women than in white women. CONCLUSIONS: In this large cohort of women with coronary artery disease undergoing PCI, we observed racial disparities primarily in baseline characteristics indicative of need for interventions to achieve early diagnosis and better prevention in black women. Future directions should include efforts to identify and better characterize the factors underlying and contributing to cardiovascular outcomes in women after PCI. SUMMARY: In this real-world analysis from a large cohort of women with coronary artery disease undergoing percutaneous coronary intervention at a US tertiary-care center, racial disparities were observed, especially in baseline characteristics, indicating late presentation.
