Methods
Patients
Thirty-six consecutive patients underwent heart transplantation by the midatrial-cuff technique between August 1992 and June1993. Nine patients were not enrolled in the study; five patients had multiple medical limitations after prolonged hospitalization, and four patients declined to participate. Within two weeks after transplantation, informed consent was obtained from the remaining 27 patients, who were randomly assigned (by selection of sealed envelopes) either to a gropu that participated in an exercise training program in an outpatient cardiac-rehabilitation setting (exercise group, 14 patients) or to a control group (13 patients). The control group received written guidelines for exercise but participated in no formal, supervised exercise sessions after discharge from the hospital.
材料与方法
All the patitents were treated with triple-drug immunosuppression, including cyclosporine,( 环孢霉素) azathioprine((硝基)咪唑硫嘌呤), and prednisone. The dosage of prednisone was initially 1 mg per kilogram of body weight per day, given in divided doses, and was gradually decreased to 0.1mg per kilogram per day by six months after transplantation. Episodes of cardiac rejection were treated with an oral bolus(〔大〕药丸) dose of prednisone and then tapered(逐渐减少) doses and, for clinically severe rejection, with OKT3 murine monoclonal antibody (muromonab-CD3). Episodes of rejecitn and infection were recorded, and blood pressure, renal function, and weight gain evaluated in both groups of patients during the study. Cardiac function was assessed with echocardiography and right-heart catheterization at base line dn at a six-month follow-up examination.
