Baseline characteristics of patients undergoing cardiac surgery.

CAD: patients with coronary artery diseases; AS: patients with aortic valve stenosis; LVEF: left ventricular ejection fraction; LVEDD: left ventricular end diastolic diameter; iLVEDD: indexed LVEDD; ST: end-diastolic septal wall thickness; PWT: end-diastolic posterior wall thickness; LAD: left atrial diameter; PAP: pulmonary artery pressure; CRP: C-reactive protein. In CAD and AS, blood glutathione was not correlated with the age (p = 0.46). Data are given as mean or percentage ±sem. P-values refer to the comparisons between CAD and AS patients.
