Cohort A (acute myocardial infarction): Acute Myocardial Infarction within 10 days (randomization/ first iron supplementation/ MRI must be performed within 10 days after AMI), without prior heart failure (defined as any known previous report of LVEF ≤ 45%) Cohort B (atrial fibrillation): Paroxysmal Atrial fibrillation or persistent AF Cohort C (heart failure): Left-ventricular ejection fraction ≤ 45 % (documented within the last 12 months prior to screening), all NYHA classes allowed

2. Confirmed presence of iron deficiency (ferritin < 100 ng/mL or ferritin 100 - 299 ng/mL with transferrin saturation < 20 %)

3. Haemoglobin ≤ 15.5 g/dL

4. Written informed consent

1. Evidence of iron overload or disturbances in the utilisation of iron

2. History of severe asthma, eczema or other atopic allergy

3. History of immune or inflammatory conditions (e.g. systemic lupus erythematosus, rheumatoid arthritis)
