Outline of ongoing trials & major publications assessing effects of treatment of iron deficiency in chronic heart failure.

Intravenous Iron in Patients With Systolic Heart Failure and Iron Deficiency to Improve Morbidity & Mortality. FAIR-HF2, (n=1200) (NCT03036462)

HF, confirmed iron deficiency, Hb 9.5-14.0 g/dL

FCM (1,000 mg, then 500- 1,000 mg within 4 weeks [max 2,000 mg total], then 500 mg every 4 months

HF hospitalizations and CV death (composite endpoint)

A Randomized, Double-Blind, Placebo-Controlled Study to Investigate the Efficacy and Safety of Injectafer® (Ferric Carboxymaltose) as Treatment for Heart Failure With Iron Deficiency. HEART-FID, NCT03037931 (n=3014)

NYHA II-IV, LVEF ≤35% or LVEF ≤25% in prior 2 years, Hb >9.0 g/dL and <13.5 g/dL (F) or <15.0 g/dL (M), ferritin <100 µg/L or 100 - 299 µg/L with TSAT <20%, either HFH within 12 months or elevated NP

FCM (2 doses of 15 mg/kg to a max. individual dose of 750 mg 7 days apart and a maxi combined dose of 1,500 mg, repeated every 6 months) vs placebo

Death and HFH at 1 year, and change in 6MWD at 6 months

Effectiveness of Intravenous Iron Treatment vs Standard Care in Patients With Heart Failure and Iron Deficiency: a Randomized, Open-label Multicenter Trial. IRONMAN, NCT02642562 (n=1299)

NYHA II-IV, LVEF <45%, Hb ≥9.0 g/dL and ≤13.0 g/dL (F) or ≤14.0 g/dL (M), ferritin <100 µg/L and/or TSAT <20% (with ferritin ≤ 400 µg/L), either HFH in 6 months or elevated NP

Iron isomaltoside (doses based on weight and Hb) vs "usual care"

CV mortality or HFH

HF with preserved LVEF (HFpEF) and diastolic dysfunction, LVEF ≥45%, NYHA II-III, either HFH within 1 year or elevated NP, Hb >9.0 g/dL and ≤14.0 g/dL, ferritin <100 µg/L or ferritin 100-299 with TSAT <20%, 6MWD <450 m

FCM vs placebo

Exercise capacity: change in 6MWD from baseline to 12 months
