Abstract

Cardiovascular disease remains the leading cause of mortality in human immunodeficiency virus-infected (HIV-positive) patients. Ventricular assist device therapy is rarely offered to these patients and data on outcomes are sparse. We investigated outcomes following ventricular assist device implants for HIV-positive as compared to non-HIV-infected (HIV-negative) patients. We analyzed 22,065 patients from the Interagency Registry for Mechanically Assisted Circulatory Support registry for outcomes by HIV status. A propensity-matched analysis adjusting for 21 preimplant risk factors was also conducted. Compared with 21,980 HIV-negative device recipients, the 85 HIV-positive recipients were younger (median age 58 years vs 59 years, p=0.02), had lower body mass index (26kg/m2 vs 29kg/m2, p=0.001), and had higher rates of prior stroke (8% vs 4%, p=0.02). In the matched HIV-positive and HIV-negative cohorts, there was significantly higher mortality in HIV-positive patients in earlier implant years, however, this association was not seen in later implant years (2018-2020). In both unmatched and matched cohorts, no significant differences in postimplantation stroke, major bleeding, or major infection were noted. With recent advancements in mechanical circulatory support and HIV treatment, ventricular assist device therapy is a viable therapeutic option for HIV-positive patients with end-stage heart failure.
