Pulse wave velocity.
Pulse wave velocity (PWV) is an additional tool to diagnose PAOD and to measure arterial stiffness.
This measurement function is an optional extra with the boso ABI-system. It allows pulse wave velocity (ba) to be measured on both sides. Pulse wave velocity (cf) then is calculated from that result.

Arterial stiffness increases with age and in response to other risk factors, especially classic cardiovascular risk factors. Increased arterial stiffness causes typical haemodynamic changes. The onset of hypertension in middle-aged and elderly individuals is closely linked to increased arterial stiffness.
Arterial stiffness readings provide useful information about the existence of functional arterial changes. Pulse wave velocity is a good predictor of the onset of cardiovascular disease. It is more accurate than classical risk parameters such as blood pressure and age.
For a better management of patients with hypertension, tests for arterial stiffness provide additional information about the cardiovascular risk. The recent guidelines published by the European Society of Hypertension (ESH) and the European Society of Cardiology (ESC) recommend the investigation of arterial function in the management of hypertensive patients.
A pulse wave velocity (cf) of 10 m/s is the threshold value for the manifestation of endorgan damage. Current hypertension guidelines state that low to normal systolic blood pressure is the therapeutic goal for these patients. In addition, a thorough cardiovascular assessment and consistent management of all cardiovascular risk factors is recommended.
