About

In China, the chronic kidney disease (CKD) incidence rate is as high as 10.8%. Renal replacement therapy plays an critical role in the later stage of CKD and becomes mandatory, as end-stage renal disease (ESRD) is unavoidable in progressive CKD. Peritoneal dialysis (PD) has becoming an essential alternative treatment for patient with end-stage renal disease (ESRD). Hypertension is common among ESRD patients receiving PD treatment, with a prevalence rate of 80% -90%, It is major cause for cardiovascular related complications and deaths among ESRD patients. Therefore hypertension increases the cardiovascular disease risk among the patients of ESRD and at the same time plays an independent risk for the progression of ESRD. Most studies uses average blood pressure as a risk indicator, but in recent years, more evidence has shown that blood pressure variability (BPV), the degree of fluctuation of blood pressure for a long period, is an additional risk factors for cardiovascular events.

Full description

Cardiovascular events can be well predicted by Blood pressure variability (BPV) and is positively correlated with cardiovascular mortality, making it more informative than average blood pressure. BPV is also an excellent predictor of renal dysfunction and is significantly linked with the advancing renal insufficiency in CKD patients. Therefore, reducing BPV has important clinical significance for PD patients. At present, the research studies on impact of BPV in PD patients is very much limited, especially on the exercise impact on BPV in PD patients. Generally speaking the average physical activity in PD patients are well decreased. Low amount of exercise is correlated to high incidence rate and mortality of cardiovascular complication, depression, muscle atrophy, and eventually decreased quality of life. Relevant guidelines recommend that PD patients should engage in appropriate physical exercise to improve the outcome. Therefore, the purpose of this study is to investigate the effect of 12 week combined aerobic and resistance exercise on BPV in PD patients, in order to provide reference point for clinical practice.

55 participants in 2 patient groups

control group
No Intervention group
Description:
Routine peritoneal dialysis care, health education, daily activity guidance, and dietary counseling were provided in accordance with the dietary guidelines for chronic kidney disease
Exercise group
Experimental group
Description:
Routine peritoneal dialysis care, health education, daily activity guidance, and dietary counseling were provided in a manner consistent with the care given to the control group-to avoid performance bias. In addition to routine basic care and treatment, the exercise group performed a combination of aerobic and resistance exercise
Treatment:
Behavioral: combination of aerobic and resistance exercise
