In vitro validation of measurement of volume elastic modulus using photoplethysmography

Cardiovascular diseases (CVD) are the foremost cause of death globally, with numerous risk factors such as diabetes, hypertension, hypercholesteremia, smoking and obesity associated with their development and progression [1 –3]. Many studies have reported that the presence of these factors is related to a change in the mechanical properties of the arterial wall and an increase in Arterial Stiffness (AS) [4–8]. AS describes the reduced capability of an artery to expand and contract in response to pressure changes.
