Valid values for age are 32-85 years for Healthy* population and 32-90 years for General population.

Diastolic diameter is measured in mm

Its range must be between 4 and 12 mm.

Following there is a picture of how it is measured:

Diastolic diameter is measured in mm

Its range must be between 4 and 12 mm.

Following there is a picture of how it is measured:

Delta is computed as systolic minus diastolic diameter and is measured in mm.

Systolic blood pressure is measured in mmHg.

It supposed to be measured in the arms.

Its range must be between 90 and 220 mmHg.

Diastolic blood pressure is measured in mmHg

It supposed to be measured in the arm

Its range must be between 40 and 120 mmHg

Pulse pressure is computed as Sistolic minus Diastolic blood pressure and is expressed in mmHg

PWV (Pulse Wave Velocity) is expressed in m/s.

Its range must be between 4 and 14 m/s.

\(DC\)

Distensibility Coefficient is expressed in \(kPa^{-1}\) and is computed as

\[DC = \frac{2\cdot\Delta D \cdot DD + \Delta D^2}{\frac{PP}{7.6}\cdot DD^2}\]

• \(\Delta D\) = Systolic Diameter - Diastolic diameter (mm)
• \(DD\) = Diastolic diameter (mm)
• \(PP\) = Pulse Pressure (mmHg)

\(PWV\)

Pulse Wave Velocity is expressed in m/s and is computed as

\[PWV = \frac{1}{\sqrt{DC \cdot \rho }}\]

where \(\rho = 1.055\),

• Healthy: individuals with no cardiovascular risk factor exposure.

• General: individuals with cardiovascular risk factor exposure, without history of coronary heart disease.
