Key result
Noninvasive arterial compliance estimation requires central BP or flow, highlighting a need for confounder-adjusted methods.
Why the study?
Numerous noninvasive methods exist to estimate arterial compliance in vivo, creating confusion regarding the selection of the best method for specific applications and measurement settings.
This review summarizes and categorizes the most common noninvasive methods for estimating arterial compliance in vivo to aid in method selection.
May limit routine clinical use of arterial compliance estimates; leaves open development of robust noninvasive methods for research.
Arterial compliance is an important cardiovascular parameter characterizing mechanical and structural properties of arteries and significantly influencing ventricular-arterial coupling. Decreased arterial compliance is associated with several physiological states and pathological processes. Furthermore, arterial compliance is influenced by other cardiovascular parameters even at short time scales. Today, there are numerous noninvasive methods of estimation arterial compliance in vivo introducing some level of confusion about selection of the best method for particular application and measurement setting. In this review, the most common noninvasive methods of arterial compliance estimation are summarized, discussed and categorized. Finally, interpretation of estimated arterial compliance in the context of other possible confounders is discussed.

Švec et al. (2021) conducted a review in Arterial compliance. Noninvasive arterial compliance estimation methods was evaluated. Noninvasive methods of arterial compliance estimation mostly require central blood pressure or blood flow measurements, highlighting the need for new methods that account for confounding variables.
