ABSTRACT
Objective To study the arterial stiffness in maintenance hemodialysis (MHD)patients and to explore the associated factors. Methods Ninety MHD patients and 36 healthy controls were enrolled in the study.Automatic pulse wave velocity (PWV) measuring system was applied to examine carotid-femoral pulse wave velocity(CFPWV)and carotid-radial PWV(CRPWV)as the parameters reflecting central elastic large arterial and peripheral muscular medium-sized arterial elasticity respectively.Blood pressure and biochemical parameters were detected.Backward muhiple linear regression analysis was used to assess the influencing factors of arterial stiffness.Results CFPWV and CRPWV in MHD patients were greater than those of healthy controls [(13.22±3.23)m/s vs(10.67±2.11)m/s and(9.58±1.87)m/s vs(8.81±1.09)m/s,all P<0.05].Backward multiple regression analysis demonstrated that age and pulse pressure were positively correlated with CFPWV,while dialysis duration,calcium phosphorus product,parathyroid hormone,low density lipoprotein and mean arterial blood pressure were signiticantly correlated with CRPWV.Volume reduction after single dialysis session could not improve arterial stiffness ofMIlD patients.Conclusions Arterial stiffness of large artery and peripheral muscular medium-sized artery increases in MHD patients.Age and pulse pressure are major determinants of large artery stiffness.Peripheral muscular medium-sized arterial stillness is more easily influenced by dialysis-associated factors.
