Part Description

LP189762-0 Cardio-ankle vascular index
The cardio-ankle vascular index (CAVI) reflects the stiffness of the aorta, femoral and tibial arteries, may be a marker of coronary arteriosclerosis, and is theoretically not affected by blood pressure. It is calculated based on measurements from EKG, phonocardiogram, brachial artery waveform, and ankle artery waveform.

Formula (Readable)

Cardio-ankle vascular index (CAVI) = a{(2ρ/ΔP) × ln (SBP/DBP)PWV2} + b, where SBP is systolic blood pressure, DBP is diastolic blood pressure, ΔP is SBP − DBP, ρ is blood density, PWV is pulse wave velocity, and a and b are constants to match aortic PWV.
