Comparison of Cardio–Ankle Vascular Index (CAVI) and CAVI<sub>0</sub> in Large Healthy and Hypertensive Populations

Abstract

CAVI showed the expected values, but CAVI₀ showed inexplicable results in the healthy and hypertensive populations. The differences were due to the strong dependency of CAVI₀ on Pd. Differences of CAVI values with or without reference pressure were negligible. These results indicate that CAVI obtained by the VaSera system is appropriate, but CAVI₀ is not.
