| Measure | Time frame |
|---|---|
| Main Objective: The principal research question addressed by this trial is to assess the effect of intravenous repletion of iron on the ability of the heart to produce energy in iron deficient heart failure patients.; Secondary Objective: The secondary research questions are the following: 1. The differential impact of iron repletion on anaemic and non-anaemic iron deficient heart failure patients in exercise capacity 2. The differential impact of iron repletion on anaemic and non-anaemic iron deficient heart failure patients in cardiac structure and function 3. The differential impact of iron repletion on anaemic and non-anaemic iron deficient heart failure patients in myocardial iron content 4. The differential impact of iron repletion on anaemic and non-anaemic iron deficient heart failure patients in blood markers of disease and iron status (e.g., iron status, electrolytes, full blood count, metabolic bloods) 5. The differential impact of iron repletion on anaemic and non-anaemic iron deficient heart failure patients in symptoms 6. The differential impact of iron repletion on anaemic and non-anaemic iron deficient heart failure patients in Quality of Life (QoL). ;Primary end point(s): Cardiac Phosphocreatine to ATP ratio (PCr:ATP) measured by 31Phosphorus Cardiac Magnetic Resonance Spectroscopy.;Timepoint(s) of evaluation of this end point: PCr:ATP ratio will be assessed at baseline and at 4 weeks after treatment. | — |

| Measure | Time frame |

| Secondary end point(s): 1.Change from baseline to week 4 in exercise capacity as assessed by the 6 minute walk distance (6MWD) 2.Change from baseline to week 4 in cardiac structure and function as assessed using magnetic resonance imaging (MRI) and echocardiography 3.Change from baseline to week 4 in myocardial iron content as assessed by T2* value on Cardiac MRI. 4.Change from baseline to week 4 in blood tests (e.g., iron status, electrolytes, full blood count, metabolic bloods) 5.Change from baseline to week 4 in symptoms (as assessed by New York Heart Association [NYHA] class and Visual Analogue Fatigue Scale [VAFS]). 6.Change from baseline to week 4 in Quality of Life (QoL) as assessed by the Kansas City Cardiomyopathy Questionnaire [KCCQ]. 7.Number and incidence of adverse events ;Timepoint(s) of evaluation of this end point: At baseline and at 4 weeks after treatment allocation | — |
