When categorized based on CD4 cell count at the time of incident HF diagnosis in PLWH, the unadjusted rate (per 100 person-years) of HF hospitalizations was not materially different across baseline CD4 count, while the rate of HF-related ED visits was highest among those with <200 CD4 cells/μL (Table 2). The gene discussed is CD4; the disease is hydrops fetalis.
