Effects of Glutamine in Ischemic Heart Disease Patients Following Cardiopulmonary Bypass

Prospective Randomized Study of Glutamin Protective Properties in Cardiac Surgery.

The purpose of this study is to determine whether perioperative glutamine administration possess protective properties on internal organs (heart and gut) in patients with coronary atherosclerosis, operated under cardiopulmonary bypass.
