Heart Failure Phenotypes and Trajectory by Gender Identity in a National Veteran Cohort

JACC AdvPublished

  • retrospective cohort study

Authors' conclusion

Gender identity is associated with differences in HF incidence and trajectory among veterans. HF epidemiology may be incompletely characterized without inclusion of TGD populations.

Study context

Population
Veterans in the Veterans Health Administration (October 1, 2010-September 30, 2019)veterans, transgender and gender diverse (TGD) status n = 42,157, 3.8%
Participants
1,103,923 veterans
Exposure
associations between gender identity, incident heart failure (HF), and trajectories between HF phenotypes

HF with reduced ejection fraction (EF) and HF with preserved EF (HFpEF)

HF with reduced EF rates were intermediate between cisgender men and women
associations with HFpEF were inconsistent after adjustment
