Authors' conclusion

In community-dwelling older adults without anaemia, lower plasma hepcidin levels associate with a higher risk of incident HF (particularly HFpEF) and diastolic dysfunction.

Study context

Population
Older adults free of anaemia and heart failure (HF) at ARIC Visit 5 (2011–13)mean age 75 ± 5 years, 56% women
Exposure
Lower vs higher plasma hepcidin levels
Outcome
Incident HF (overall adjudicated), HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF)
