Heart failure & cardiomyopathies
Hepcidin, incident heart failure, and cardiac dysfunction in older adults: the Atherosclerosis Risk in Communities (ARIC) study
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)
Methodological detailscommunity-based, longitudinal
- Community-based
