ObjectiveWe examined the relationship between Black or White race and adverse outcomes in patients who underwent surgery of the ascending aorta, aortic root, or aortic arch at our center.MethodsWe analyzed 2335 consecutive patients who identified as Black (n = 217, 9.3%) or White (n = 2118, 90.7%) and underwent proximal aortic surgery. Patient zip codes were used to determine community socioeconomic (CSE) characteristics. The composite adverse outcome comprised mortality, persistent neurologic injury, and renal failure necessitating dialysis at discharge. We performed multivariable analysis, Kaplan-Meier analysis, and propensity score matching adjusted for CSE factors.ResultsMedian follow-up time was 3.7 years. Compared with White patients, Black patients lived in areas characterized by a higher percentage living below poverty level, lower income, and lower education level (P < .0001). Black patients had higher rates of emergency presentation (P < .0001) and lower 5- and 10-year survival rates (P = .0002). Short-term outcomes were similar between groups, except for respiratory failure and length of stay (P < .0001), which were higher in the Black population. After propensity score matching adjusted for CSE factors, Black and White patients (n = 204 each) had similar short-term outcomes and 5- and 10-year survival rates (P = .30). Multivariable analysis stratified by race showed that CSE factors independently predicted adverse outcomes in Black but not White patients.ConclusionsThis is among few studies that have analyzed the relationship between race and proximal aortic surgery. Although outcomes were similar between Black and White patients in our cohort after adjusting for CSE factors, unfavorable CSE factors predicted adverse outcomes in Black but not White patients. More patient-specific studies are needed.Copyright © 2022 The Authors. Published by Elsevier Inc. All rights reserved.
