Primary Outcome Measures:
  • Change in haemoglobin (Hb) concentrations [ Time Frame: From t=0 to t=4 weeks postoperatively ] [ Designated as safety issue: No ]
    To demonstrate that intravenous iron isomaltoside 1000 (Monofer®) is superior compared to placebo with respect to increasing the haemoglobin level in non- anaemic patients undergoing cardiac surgery


Secondary Outcome Measures:
  • Change in Hb concentrations [ Time Frame: t=0, t=5 days and t=4 weeks ] [ Designated as safety issue: No ]
    Proportion of patients that are anaemic (women < 12 g/dL and men < 13 g/dL) at day 5 and week 4

  • Number of patients in each randomisation group who need blood transfusion and number of transfusions administered [ Time Frame: From t=0 to t=day 5 and t=4 weeks ] [ Designated as safety issue: No ]
    To compare the number of patients who will need blood transfusion and number of transfusions in each randomisation group

  • Change in concentrations of serum ferritin, serum iron and Transferrin Saturation (TfS) TfS, and reticulocytes [ Time Frame: Change from baseline (preoperatively- the day before surgery or same day) in concentrations of serum ferritin, serum iron and Transferrin Saturation (TfS) TfS, and reticulocytes at 4 weeks and 3 months postoperatively ] [ Designated as safety issue: No ]
    From t=0 to t=day 5 and t=4 weeks

  • Number of postoperative days to discharge [ Time Frame: From t=0 to discharge ] [ Designated as safety issue: No ]
    To compare the number of days to discharge between the 2 randomisation groups

  • Changes in New York Heart Association (NYHA) classification [ Time Frame: From t=0 to t=4 weeks ] [ Designated as safety issue: No ]
    To compare the changes in New York Heart Association (NYHA) classification from baseline to 4 weeks postoperatively

  • Number of patients in each randomisation group who experience any study drug related adverse events (AEs/SAEs/SUSARs) [ Time Frame: From screening and until completion (t=-7 day and upto t=4 weeks) ] [ Designated as safety issue: Yes ]
    To compare the number of study drug related adverse events (AEs/SAEs/SUSARs) between subjects treated with iron isomaltoside 1000 (Monofer®) infusion and subjects treated with placebo infusion

  • Change in Hb [ Time Frame: t=0, t=day 5 and t=week 4 ] [ Designated as safety issue: No ]
    Proportion of patients able to maintain Hb between 9.5 and 12.5 g/dL (both values included) at day 5 and week 4

Detailed Description:

The role of preoperative haemoglobin as a predictor of short-term and long-term outcomes after cardiac surgery has been well established. Anaemia can impede a patient's ability to recover fully and participate in postoperative rehabilitation. It has been found that patients with a normal haemoglobin level may become anaemic during surgery. An evaluation of patients undergoing cardiac surgery, i.e. CABG, valve or combined CABG-valve procedures showed that there was a decrease in mean haemoglobin level pre-surgery two and four days after surgery. To date, no prospective randomised clinical study in cardiac surgery assessing the effect of intravenous iron supplementation in patients undergoing cardiac surgery has been reported. This prospective, randomized, placebo controlled, double blind study is planned to evaluate the effect of intravenous iron isomaltoside 1000 (Monofer®) in comparison with placebo in non-anaemic patients undergoing cardiac surgery.
