Blood glutathione level in cardiac patients and in the subgroups of patients with coronary artery diseases (CAD) or aortic stenosis (AS).

<p>(A) In patients undergoing cardiac surgery, the decrease in blood glutathione level was related to NYHA class (linear trend P<0.0001). (B) Compared to healthy controls, blood glutathione level in the CAD and AS subgroups of patients was depleted, independently of the LVEF value. *P<0.05 vs healthy controls (C); †P<0.05 vs NYHA class I.
