Background/Aims: Possible predictive value of aortic-brachial arterial stiffness mismatch assessed by pulse wave velocity PWV ratio in peritoneal dialysis patients’ outcomes need to be further elucidated. The aim of this study is to investigate the predictor value of PWV ratio on peritoneal dialysis (PD) patients’ outcomes in China. Methods: In this longitudinal cohort study, patients who started PD during September 20, 2005, to February 05, 2008, were included. All the patients were followed until January 31, 2018. Aortic-brachial arterial stiffness mismatch was assessed using carotid-femoral pulse wave velocity divided by carotid-radial pulse wave velocity (PWV ratio). Results: A total of 181 incident PD patients were included. The median survival of patients in PWV ratio above median group (4.03 years, 95% CI 4.64-7.99 years) was shorter than that of PWV ratio below median group (10.43 years, 95% CI 9.74-11.12 years, p< 0.001). The cardiovascular mortality rate in PWV ratio above median group were significantly higher than that of PWV below median group (log rank test, p< 0.001). Univariate Cox regression analysis showed that both PWV ratio (HR 2.42, 95% CI 1.80-3.25, p< 0.001) and CF-PWV (HR 1.27, 95% CI 1.16-1.38, p< 0.001) were associated with high patients’ all-cause mortality. Multivariable Cox regression analysis showed that the PWV ratio was a strong and significantly predictor of cardiovascular mortality (HR 2.08 95% CI 1.16-3.71, p=0.014) after adjusting for coronary heart disease history (HR 2.39, 95% CI 1.20-4.76, p=0.013), diabetes mellitus history (HR 2.84, 95% CI 1.51-5.33, p=0.001). However, the CF-PWV was failed to be included as a significant predictor for both all-cause and CVD mortality in the multivariable Cox regression model. Conclusion: Aortic-brachial arterial stiffness mismatch as assessed by PWV ratio, a new arteries stiffness risk parameter, is a significant prognostic indicator of CVD mortality in PD patients. We demonstrated that the discriminative power of the PWV ratio for both all-cause and CVD mortality was better than that CF-PWV.

ObjectiveCardiovascular disease (CVD) is the most common cause of mortality in chronic peritoneal dialysis (PD) patients. Increased arterial stiffness may be related to a high peritoneal permeability resulting in fluid overload in PD patients. We studied the relations between arterial stiffness, peritoneal transport, and radiographic parameters of systemic fluid overload in a cohort of Chinese PD patients.DesignProspective cohort study.SettingUniversity referral center.PatientsWe studied 107 PD patients. Vascular pedicle width and cardiothoracic ratio were measured from a plain postero-anterior chest radiograph. Pulse wave velocity (PWV) was determined at carotid–femoral (C-F) and carotid–radial sites. Peritoneal transport was determined by the dialysate-to-plasma ratio (D/P) of creatinine at 4 hours of dwell. Patients were followed for 9.4 ± 4.6 months.Outcome MeasuresDuration of hospitalization; actuarial and technique survival.ResultsThere were no relationships between radiographic measures, arterial PWV, and D/P creatinine. However, both C-F PWV and D/P creatinine were independent predictors of the number of hospitalizations for CVD. None of the parameters correlated with mortality in this study.ConclusionsThere were no relationships between radiological parameters of fluid overload, peritoneal transport characteristics, and arterial PWV. Both C-F PWV and D/P creatinine were independent predictors of the number of hospitalizations for CVD. Our result suggests that arterial stiffness and high peritoneal transport each contribute to the development of CVD in this group of patients.

AbstractElevated pulse wave velocity (PWV) reflects increased arterial stiffness. Several studies have investigated PWV in peritoneal dialysis (PD) patients, but direct comparisons with healthy controls were not done. The potential influence of peritoneal transport characteristics on arterial stiffness in PD patients was suggested in recent studies. The aims of this study were to compare PWV in PD patients and healthy volunteers, and to investigate factors associated with increased PWV. The carotid-femoral PWV was measured in 28 PD patients and 28 healthy controls, matched for age and gender. A peritoneal equilibration test (PET) was performed in all PD patients. Based on the PET, patients were classified as: high transporters (H) (n=8), high-average (HA) (n=12), low-average (LA) (n=6), and low transporters (L) (n=2). Six of the PD patients were diabetic. PWV was significantly higher in the PD patients than in the controls (9,9±2,4 vs. 8,0±0,9; p=0,0004). In the PD group, PWV was higher in H/HA than in L/LA patients (10,4 ± 2,5 vs. 8,6 ± 1,0; p=0,008), but all the diabetic patients were in the H/HA group. PWV was significantly higher in diabetic than in non-diabetic PD patients (12,8 ± 2,0 vs. 9,1 ± 1,7; p=0,004). In the PD patients, significant positive correlations were found between PWV and: age, pulse pressure, Kt/V, and duration of PD therapy. In conclusion, the carotid-femoral PWV is elevated in peritoneal dialysis patients. Increased PWV in PD patients is associated with age, diabetic status, and longer duration of PD therapy, but not with this type of peritoneal transport.

Background and objective Elevated pulse wave velocity (PWV) has been associated with higher mortality in the general population, chronic kidney disease (CKD) patients, and hemodialysis patients. However, in peritoneal dialysis (PD) patients, this association has received little attention. The aim of this study was to evaluate the association between baseline brachial-ankle PWV (baPWV) levels and total mortality in PD patients. Methods In this single-center retrospective cohort study, 254 incident PD patients with baseline baPWV were followed up from 1 January 2013 to 31 July 2016. Collected baseline data included demographic characteristics and clinical and laboratory measurements. The association of baseline baPWV levels with total mortality was assessed using multivariable-adjusted Cox models. Results Of 254 patients, mean age was 61.4 (±15.3) years, 61.4% of patients were men, and 22.4% of patients were diabetic. The mean baseline baPWV level was 17.6 (±5.84) m/s. During a mean 31.5 (±20.8) month follow-up period, 45 patients died, of which 13 deaths were caused by cardiovascular disease. After adjusting for sex, age, blood pressure (BP), body mass index (BMI), and hemoglobin, as well as serum albumin, calcium, phosphorus, intact parathyroid hormone (iPTH), uric acid, and medication use, the highest baPWV tertile was significantly associated with a hazard ratio (HR) for total mortality of 2.97 (95% confidence interval [CI], 1.23 – 7.16; p = 0.02). Each 1 m/s higher baseline baPWV level was associated with a 7% (95% CI, 1.03 – 1.12; p = 0.001) higher risk of total mortality. In sensitivity analyses, individuals with baPWV > 21.0 m/s had the highest adjusted risk for total death (HR, 3.22; 95% CI, 1.71 – 6.08; p < 0.001). Conclusion Higher baseline baPWV levels at the commencement of PD were independently associated with total mortality, which suggests that clinicians could use baPWV as a predictor of higher risk of mortality in PD patients.
