Arterial Stiffness, Pulse Wave Analyses: What Can’t Blood Pressure Tell you in Chronic Kidney Disease
Biagio Di Iorio.
Increased arterial stiffness is emerging as a useful marker of cardiovascular damage. A growing body of
evidence suggests that the stiffening of the conduit arteries is linearly associated with poor survival in the general
population and high-risk population such as Chronic Kidney Disease (CKD) patients. Indeed, the loss of the elastic
properties of conduit arteries induces an increase in the central pulse pressure and cardiac workload leading to left
ventricular hypertrophy and reduced coronary and capillary perfusion. Notably, all these changes are independent of mean
blood pressure and other established cardiovascular risk factors.
Though, evidence is still inconclusive, some preliminary data suggest that arterial stiffness and central blood pressure
evaluation can be of use for risk stratification and treatment individualization. We herein summarize the current evidence
supporting the usefulness of arterial stiffness assessment for CKD patients’ management.
