Effects of Exercise Therapy on Ventricular and Endothelial Function in Patients After Coronary Artery Bypass Surgery

November 15, 2013 updated by: National Taiwan University Hospital
The purpose of this study was (1) to compare the peak exercise capacity and left ventricular diastolic function between patients with and without diabetes and (2) to investigate the interrelation among peak oxygen consumption, left ventricular diastolic function, blood sugar, and lipid profile.
