Background: There are limited data regarding racial disparities in outcomes after left ventricular assist device (LVAD) implantation. The purpose of this study was to compare clinical characteristics and the burden of readmissions by race among patients with LVAD. Methods: The study population included 461 patients implanted with LVADs at the University of Rochester Medical Center, NY from May 2008 to March 2020. Patients were stratified by race as White patients (N = 396 [86%]) and Black patients (N = 65 [14%]). The Anderson-Gill recurrent regression analysis was used to assess the independent association between race and the total number of admissions after LVAD implant during an average follow-up of 2.45 ± 2.30 years. Results: Black patients displayed significant differences in baseline clinical characteristics compared to White patients, including a younger age, a lower frequency of ischemic etiology, and a higher baseline serum creatinine. Black patients had a significantly higher burden of readmissions after LVAD implantation as compared with White patients 10 versus 7 (average number of hospitalizations per patient at 5 years of follow-up, respectively) translated into a significant 39% increased risk of recurrent readmissions after multivariate adjustment (Hazard ratio 1.39, 95% CI; 1.07–1.82, p 0.013). Conclusion: Black LVAD patients experience an increased burden of readmissions compared with White patients, after adjustment for baseline differences in demographics and clinical characteristics. Future studies should assess the underlying mechanisms for this increased risk including the effect of social determinants of health on the risk of readmissions in LVAD recipients.
