An Open Study on the Efficacy of Iron Therapy Using iv Iron Relative to Oral Iron for Increasing LV Systolic Function

For this study an open-label prospective randomized approach is used. During the study 360 patients with or without ID, who hospitalized for myocardial infarction were signed up. Patients were randomised (1:1) to either intravenous. FCM or oral ferrous sulphate and received the treatment during hospitalisation. Patients are closely followed for 1 year. The primary outcome is a decrease in the Wall Motion Score Index value in FCM group compered to ferrous sulphate group. The main secondary outcome includes the composite of cardio-vascular mortality, non-fatal stroke, non-fatal MI, recurrent heart failure hospitalizations.

Inclusion criteria

• Adult (≥18 years of age) able to provide informed consent. Hospitalized myocardial infarction patients (that diagnosed according to Fourth Universal Definition of myocardial infarction and myocardial injury, ESC 2018) with hypokinesia or akinesia in at least two connected left ventricular segments according to echocardiography results obtained within the first 24 hours after myocardial infarction occurs.
• Hemoglobin >9.0 g/dL and <15,0 g/dl and serum iron <12 µmol/l on screening visit.
• Serum ferritin <100 μg/L, or 100-299 μg/L when transferrin saturation <20%.

Exclusion criteria

• Known hypersensitivity reaction to any component of ferric carboxymaltose.
• History of acquired iron overload, or the recent receipt (within 3 months) of erythropoietin stimulating agent, i.v. iron therapy, or blood transfusion.
• Heart failure Killip class II-IV on screening visit.
• Current or planned mechanical circulatory support or heart transplantation.
• Hemodialysis or peritoneal dialysis (current or planned within the next 6 months).
