Heart failure & cardiomyopathies
Plasma Ferritin Levels, Incident Heart Failure, and Cardiac Structure and Function: The ARIC Study
Authors' conclusion
Among older adults without prevalent HF or anemia, lower plasma ferritin level is associated with a higher risk for incident HF, HFpEF, and higher measures of left ventricular filling pressure.
Study context
- Population
- Older adults in the ARIC study free of prevalent heart failure (HF) and anemiamean age 75 ± 5 years
- Participants
- 3,472 adults
- Exposure
- Lower vs higher plasma ferritin level
- Outcome
- Incident HF overall, heart failure with preserved ejection fraction (HFpEF) and HFrEF; echocardiographic cardiac structure and function
Methodological detailslongitudinal, fully adjusted Cox proportional hazards models
- Longitudinal
- Fully adjusted Cox proportional hazards models

Per 50% lower ferritin, as printed
Observational data: associations, not effects.
Further findings
Echocardiographic cardiac structure and function (cross-sectional)
- Lower ferritin associated with higher E/e' ratio and higher pulmonary artery systolic pressure
- No association with LV structure or systolic function
- Adjusted for demographics and HF risk factors
