Abstract

Structural and functional dysfunction in both the macro- and microvasculature area feature of essential hypertension. In a healthy cardiovascular system, the elasticproperties of the large arteries ensure that pulsations in pressure and flow generated bycyclic left ventricular contraction are dampened, so that less pulsatile pressure and floware delivered at the microvascular level. However, in response to aging, hypertension,and other disease states, arterial stiffening limits the buffering capacity of the elasticarteries, thus exposing the microvasculature to increased pulsatile stress. This is thoughtto be particularly pertinent to high flow/low resistance organs such as the brain andkidney, which may be sensitive to excess pressure and flow pulsatility, damaging capillarynetworks, and resulting in target organ damage. In this review, we describe the clinicalrelevance of the pulsatile interaction between the macro- and microvasculature andsummarize current methods for measuring the transmission of pulsatility between thetwo sites.
