  • Retrospective cohort study
  • registry (OPTN database)

Authors' conclusion

Use of HM3 among patients listed for HT has increased over time and by gender and race. Black patients with HM3 were less likely to be transplanted compared with White patients, but there were no differences in post-transplant outcomes between these groups or between men and women.

Study context

Population
Patients listed for heart transplantation (HT) who received left ventricular assist device (LVADs) as bridge to transplantation (BTT), OPTN database, January 2018–June 2020955 (8.3%) with HM3 as BTT
Participants
11,524 patients
Exposure
Outcomes with HM3 LVAD as BTT by gender and race
Outcome
Use of HM3, waitlist outcomes (transplantation; death/delisting) and post-transplant outcomes by gender and race

Main finding

As reported in the abstract

Waitlist outcomes (competing risk)
Adjusted hazard ratio (95% CI)
Men vs WomenHT
0.92(0.70–1.21)

Use of HM3 increased for all patients; no difference in use by gender
P = 0.4
No difference in HM3 use by race
P = 0.2

Observational data: associations, not effects.

Further findings

1-year post-transplant survival

Comparable by gender
0.52 [95% CI: 0.21-1.70] (aHR [95% CI])
Comparable by race
0.76 [95% CI: 0.34-1.70] (aHR [95% CI])

Post-transplant stroke, acute rejection, graft failure

No differences in rates of stroke, acute rejection or graft failure
