• W4382364218 abstract "Durable left ventricular assist devices (VADs) improve survival in eligible patients, but allocation has been associated with patient race in addition to presumed heart failure (HF) severity. This study sought to determine racial and ethnic differences in VAD implantation rates and post-VAD survival among patients with ambulatory HF. Using the INTERMACS (Interagency Registry of Mechanically Assisted Circulatory Support) database (2012-2017), this study examined census-adjusted VAD implantation rates by race, ethnicity, and sex in patients with ambulatory HF (INTERMACS profile 4-7) using negative binomial models with quadratic effect of time. Survival was evaluated using Kaplan-Meier estimates and Cox models adjusted for clinically relevant variables and an interaction of time with race/ethnicity. VADs were implanted in 2,256 adult patients with ambulatory HF (78.3% White, 16.4% Black, and 5.3% Hispanic). The median age at implantation was lowest in Black patients. Implantation rates peaked between 2013 and 2015 before declining in all demographic groups. From 2012 to 2017, implantation rates overlapped for Black and White patients but were lower for Hispanic patients. Post-VAD survival was significantly different among the 3 groups (log rank P = 0.0067), with higher estimated survival among Black vs White patients (12-month survival: Black patients: 90% [95% CI: 86%-93%]; White patients: 82% [95% CI: 80%-84%]). Low sample size for Hispanic patients resulted in imprecise survival estimates (12-month survival: 85% [95% CI: 76%-90%]). Black and White patients with ambulatory HF had similar VAD implantation rates but rates were lower for Hispanic patients. Survival differed among the 3 groups, with the highest estimated survival at 12 months in Black patients. Given higher HF burden in minoritized populations, further investigation is needed to understand differences in VAD implantation rates in Black and Hispanic patients." @default.
