Townsend et al Vascular Research on Arterial Stiffness 699 pressure, blood flow, and arterial diameter change with each heartbeat. In addition to the passive mechanical properties of the load-bearing structures, arterial stiffness can be modulated by functional components related to cellular processes in which wall stiffness can be affected by endothelial function through modulation of smooth muscle tone or by alterations in the integrity of the extracellular matrix. As developed in this summary statement, stiffness is measured in different kinds of arteries (muscular, elastic) and in cross section, longitudinally along the vessel, or in both directions. Often, arterial stiffness is assessed as the velocity of pulse-wave travel in a defined segment such as the aorta. However, the research questions addressed by investigations of arterial stiffness are not restricted to this use, and stiffness has been measured in most named large arteries in humans. 2 Arterial stiffness is also estimated by measuring pressure or diameter in a vessel and applying 1 or several of the now extensive formulas to the data to derive a value that reflects this inherent property of all arteries. 3
