Pulse Wave Velocity: A Valuable Predictor for Cardio-Cerebrovascular Disease and Death in PD Patients

Area of Science:

• Nephrology
• Cardiology
• Vascular Biology

Background:

• Cardiovascular and cerebrovascular disease (CVD) are leading causes of mortality in patients undergoing peritoneal dialysis (PD).
• Arterial stiffness, assessed by pulse wave velocity (PWV), is an emerging risk factor for CVD in various populations.
• The predictive value of PWV for CVD and mortality specifically in PD patients requires further investigation.

Purpose of the Study:

• To evaluate the prognostic value of carotid-femoral pulse wave velocity (CF-PWV) in predicting cardio-cerebrovascular events and death among maintenance PD patients.

Main Methods:

• A cohort of 59 maintenance PD patients was enrolled between January 2012 and December 2012.
• Patients were categorized into two groups based on CF-PWV measurements: Group A (>9 m/s) and Group B (≤9 m/s).
• Clinical data, including age and 24-hour average systolic blood pressure (SBP), were collected and analyzed.

Main Results:

• CF-PWV showed significant positive correlations with age, left atrial diameter, left ventricular mass index, and 24-hour average SBP.
• Age and 24-hour average SBP were identified as independent risk factors for elevated CF-PWV.
• Patients in Group A (higher CF-PWV) exhibited significantly lower cumulative and new CVD-free survival rates compared to Group B.

Conclusions:

• Pulse wave velocity is a valuable and independent predictor of cardiovascular and cerebrovascular disease and mortality in PD patients.
• Higher arterial stiffness, as indicated by elevated PWV, is associated with increased CVD risk in the PD population.
• Integrating PWV assessment into routine clinical practice for PD patients may aid in risk stratification and management.
