Abstract:
Objective To study the influence of walking exercise training on heart function, left heart ventricle structure and plasma brain natriuretie peptide (BNP) concentration in patients with chronic heart failure ( CHF), to explore the sense of exercise training.Methods A total of 223 CHF patients were randomly assigned to a guided rehabilitation group, a non-guided rehabilitation group and a control group.All patients were given basic medicine treatment, and the guided rehabilitation group was administered guided walking exercise training program, while the non-guided rehabilitation group was encouraged to do exercise freely but with no guidance.Blood pressure, 6 min walking distance test, plasma concentration of BNP and echocardiography were measured in all patients before and after exercise training.Results At entry to the study, there was no significant difference among the 3 groups with regard to blood pressure, 6 rain walking distance and BNP level as well as echocardiographic parameters including left ventrieular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDd).A follow-up at the 6th month after intervention, the amount of readmission patients in guided rehabilitation group were significantly less than those in non-guided rehabilitation and control groups ( P < 0.05 ).It was also revealed that the plasma concentration of BNP decreased significantly ( P < 0.01 ) ; LVEF and 6 min walking distance improved significantly ( P < 0.01 ) in the guided rehabilitation group when compared with baseline and 6-month follow-up of the non-guided rehabilitation and control groups.However, there observed no significant change with regard to LVEDd.Conclusion Walking exercise training can improve exercise endurance in CHF patients and is safety; but has no influence on left heart ventricular structure in short time.
