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

Main finding

As reported in the abstract

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
