Main objective
Scope: Prophylaxis, Therapy
To establish the efficacy of intravenous glutamate infusion to prevent acute kidney injury (AKI) after coronary artery bypass surgery (CABG) among high-risk patients without diabetes.
Secondary objectives 3
- To establish the efficacy of intravenous glutamate infusion to mitigate postoperative increase of NT-proBN after coronary artery bypass surgery among high-risk patients without diabetes
- To assess the impact of glutamate infusion on biomarkers of tubular kidney injury after CABG among high-risk patients without diabetes
- To assess the impact of perioperative glutamate infusion on kidney function 6 months following CABG

Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 1
- Adult patients without diabetes operated on heart-lung machine with CABG of at least two vessel disease or left main stenosis with or without a concomitant procedure and who either have EuroSCORE II ≥ 3.0 to which at least one cardiac or procedure related risk factor contribute or Left Ventricular Ejection Fraction ≤ 0.30 regardless of EuroSCORE II
Exclusion criteria 1
- Diabetes; ambiguous food allergy known to have elicited flushing, headache, rash or asthma; age > 85 years; previous cardiac surgery; informed consent not possible because of critical condition or other reason; preoperative use of inotropic support or mechanical circulatory assist; preoperative dialysis or calculated Creatinine clearance < 30 mL/min; surgery without heart-lung machine (off-pump); concomitant Maze-procedure; surgery of ascending aorta necessitating circulatory arrest; surgery of both aortic and mitral valve.
Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- Incidence of postoperative acute kidney injury (AKI) measured as >= 50% postoperative increase of p-creatinine compared to preoperative value
Secondary endpoints 3
- Postoperative increase of p-NT-proBNP from the day before surgery to the third postoperative day
- Plasma - neutrophil gelatinase–associated lipocalin (NGAL) on postoperative day 3
- Estimated creatinine clearance (Cockcroft–Gault) at 6 months following surgery related to preoperative level
