Brief Summary:
The aim of the investigators' research program is to investigate the effects of perioperative high dose selenium supplementation in high-risk cardiac surgical patients undergoing complicated open heart surgery. The investigators hypothesize that the therapeutic strategy tested in this randomized trial may contribute to a fewer complications, less organ injury and fewer deaths. Before the investigators conducted the large definitive trial, they conducted a pilot study to assess the feasibility of the protocol, and are rolling the pilot patients into the definitive trial.

Condition or disease Intervention/treatment Phase
Heart Disease Drug: sodium selenite Drug: Placebo Phase 3

Detailed Description:

Over a million patients undergo open heart surgery annually and this number is likely to accelerate as the population ages and the prevalence of diabetes and cardiovascular disease continue to increase. Unfortunately, death, organ failure, and other serious complications are all too frequent following open heart surgery, especially in some high-risk patient populations.

Selenium is a trace element that is important for many of the body's regulatory and metabolic functions especially during times of stress. International members of the study team have shown in a non-randomized study that high dose selenium supplementation was associated with improved clinical outcomes compared to a historical control group. The next step in this program of research is to conduct a randomized trial.

The aim of this research program is to investigate the effects of perioperative high dose selenium supplementation in high-risk cardiac surgical patients undergoing complicated open heart surgery. The investigators hypothesize that the therapeutic strategy tested in this randomized trial may contribute to fewer complications, less organ injury and fewer deaths.

The investigators propose to conduct a randomized, placebo-controlled, double-blind, multicentre definitive trial of 1400 patients across 20 sites in Germany and Canada, which will include the pilot study patients. An industry partner (Biosyn) will provide the product and some additional support for the European sites. Patients will be randomized to receive either a daily perioperative high-dose selenium or placebo until postoperative day 10 (maximum) or upon earlier discharge from ICU. If the hypothesis is proven true, and this simple, inexpensive nutrient reduces complications and improves recovery of patients undergoing cardiac surgery, there is the potential to dramatically change clinical practice and improve health outcomes.

Arm Intervention/treatment
Placebo Comparator: Placebo
Normal saline will be administered to subjects intravenously pre-operatively, upon admission to the ICU, then daily up to post-operative day 10 or ICU discharge, whichever occurs first.
Drug: Placebo
All patients will receive an IV bolus of normal saline (equals to 40ml prepared solution) within 30min after induction of anesthesia via the central venous catheter. After termination of surgery, immediately after admission to the ICU, all patients will receive a second bolus of normal saline accordingly. Then on every further morning during ICU-stay, patients will receive an IV bolus of normal saline via central or peripheral venous access until death, discharge from ICU to the ward (treatment may continue in a step down or intermediate care unit), or for a maximum of 10 days.
Other Name: NaCl 0.9%

Active Comparator: sodium selenite

High-dose sodium-selenite will be administered to subjects intravenously:

1) pre-operatively (2000 ug); 2) upon admission to the ICU (2000 ug), 3) then daily (1000 ug) up to post-operative day 10 or ICU discharge, whichever occurs first.

Drug: sodium selenite
All subjects will receive an IV bolus of 2000µg selenium within 30min after induction of anesthesia via the central venous catheter. After termination of surgery, immediately after admission to the ICU, all patients will receive a second bolus of 2000µg selenium. Then on every further morning during ICU-stay, patients will receive an IV bolus of 1000µg selenium via central or peripheral venous access until death, discharge from ICU to the ward, or for a maximum of 10 days.
Other Name: selenium




Primary Outcome Measures :
  1. PODS free days + alive [ Time Frame: 30 Day ]
    Evaluate the PODS free days + alive as the primary outcome for the large-scale Phase III trial. We define PODS as the need for life-sustaining therapies (mechanical ventilation, vasopressor therapy, mechanical circulatory support, continuous renal replacement therapy, or intermittent hemodialysis).


Secondary Outcome Measures :
  1. 30-Day Mortality [ Time Frame: 30 Day ]
    Mortality 30 days post-randomization.

  2. Hospital Acquired Infections [ Time Frame: 30 day ]
    To be evaluated up to 6 months post-randomization.

  3. Perioperative hemodynamic profile [ Time Frame: 6 months ]
    This includes: mean arterial blood pressure, cardiac power index, systemic vascular resistance, etc... To be assessed up to 6-months post-randomization.

  4. Cardiovascular Complications [ Time Frame: 6-months ]
    This includes: arrhythmias, cardiac arrest, infarction. To be assessed up to 6-months.

  5. Duration of Mechanical Ventilation [ Time Frame: 6-months ]
    To be assessed up to 6-months.

  6. Incidence of post-operative delirium [ Time Frame: 6-months ]
    Assessed by CAM-ICU score. To be assessed up to 6-months.

  7. ICU Length of stay [ Time Frame: 6-months ]
    To be assessed up to 6 months post-randomization.

  8. Hospital Re-admission Rates [ Time Frame: 6-months ]

    To be assessed up to 6 months post-randomization.

    To be assessed at 6 months post-randomization.

    Health related quality of life to be assessed up to 6-months post-randomization.

  12. Return to work [ Time Frame: 6-months ]

Other Outcome Measures:
  1. Laboratory outcomes [ Time Frame: POD 10 ]

    To be assessed up to post-operative day (POD) 10 in patients who consent to this optional blood work.

    To assess the potential effects of supplementation on selenium levels, safety parameters and other mechanistic markers. Whole blood levels of selenium, selenoprotein P (Sel-P), antibodies against oxidized LDL, markers of inflammation (interleukin[IL]-6, IL-10, TNF alpha) and activity of glutathione-peroxidase (GPx) will be assessed to determine the efficacy of selenium supplementation in these patients.
