Summary

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.

Detailed 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.

Conditions

• CKD (Chronic Kidney Disease) Stage 5D
• Peritoneal Dialysis (PD)

Interventions

Type	Name	Description
BEHAVIORAL	combination of aerobic and resistance exercise	Aerobic exercise: The main form is walking(gait), which includes three parts: warm-up, walking, and relaxation. Exercise time and frequency: 30-60 minutes of exercise per day, 3-5 times per week. Resistance exercise: Mainly uses elastic bands to enhance resistance exercise, since the risks of increased intra-abdominal pressure and fluid leakage in peritoneal dialysis patients is high, Investigator considered selective resistance exercise especially for limb and shoulder joint exercises. Patients can choose 3-5 muscle groups based on individual conditions, with each action 10-15 times and maintained for 10 seconds. Start with 2 sets of resistance exercise and then gradually increase to 3-5 sets, with 2-3 minutes of rest between each sets. Exercise frequency and duration: 2 times a week (non-consecutive days), 20 minutes each time.
