Table 2 A summary of the advantages and disadvantages of different measurements for evaluating arterial stiffness
AdvantageDisadvantage
cfPWV[42-44]Reflects the stiffness of the descending aorta The gold standard measure for arterial stiffnessLargely affected by the change of BP Overestimated for the inaccurate measurement in the distance between the carotid and the femoral arteries
baPWV[116]Reflects the stiffness of both the descending aorta and the leg artery High association with CV risk factors Ease of use for large-scale population studiesLargely affected by the change of BP Underestimates arterial stiffness in hypertensive patients with a history of cardiovascular events
hfPWV[117]Strongly correlated with cfPWV moderately correlated with baPWVRequire a high level of proficiency in order to obtain accurate results
faPWV[117]Moderately correlated with baPWVThe predictive value to incident vascular events remains unknown
pAIx[110]Assessed non-invasively and peripherally, e.g., carotid, and radial arteries Correlated well with the central AIxLargely affected by the change of BP Not a valid surrogate of arterial compliance in the elderly and diabetic populations
The stiffness parameter β[53,54]Independent of the change of BPAssessing only a local segment of the artery Loss of the independence of BP for those with moderate to severe hypertension or hypotension
CAVI[118]Independent of the change of BP A novel atherosclerotic index that incorporates PWV and BP measurements The coefficients of variation are small (< 4%), and does not require significant trainingCAVI, as a cardiovascular risk marker has not to be investigated definitively in large prospective clinical trials
