Heart failure & cardiomyopathies

Cardiac allograft vasculopathy mediates the relationship between vitamin D deficiency and cardiovascular mortality following heart transplantation

Am Heart JPublished Prospective cohort study

Authors' conclusion

VDD is an independent predictor of all-cause mortality, cardiovascular mortality, and presence of CAV in patients with OHT.

Study context

Population
Patients after orthotopic heart transplantation (OHT)
Participants
327 patients
Exposure
Vitamin D deficiency (VDD) vs no VDD
  • VDDn = 95
Outcome
Baseline presence of CAV and all-cause and CV mortality
Follow-up
5 years

Main finding

As reported in the abstract

VDD vs No VDDEstimate (95% CI)
5-year all-cause mortality, adjusted
HR 2.08(1.20–3.60)
CV death, adjusted
SHR 2.21(1.13–4.31)
Presence of CAV, adjusted
OR 3.08(1.39–6.80)

Observational data: associations, not effects.

Further findings

Interaction VDD × cardiac allograft vasculopathy (CAV) on CV death; mediation by CAV grade

Interaction between VDD and CAV on CV death
P = 0.042
CAV grade accounts for share of association between VD and CV mortality
26.5%
  • Interaction P = .042
