Editorial Commentary Arterial Baroreflex Modulation of Sympathetic Activity and Arterial Wall Properties New Evidence
The arterial baroreflex is among key fast-reacting mechanisms maintaining cardiovascular homeostasis, in particular, regulating blood pressure (BP). Baroreflex influences stemming from stretch receptors located mainly in the carotid arteries and in the aortic arch are triggered by changes in transmural pressure of these vessels. The effector arm is directed toward cardiac and vascular targets a...

متن کاملModulation of arterial baroreflex control of muscle sympathetic nerve activity by muscle metaboreflex in humans.
We aimed to investigate the interaction [with respect to the regulation of muscle sympathetic nerve activity (MSNA) and blood pressure] between the arterial baroreflex and muscle metaboreflex in humans. In 10 healthy subjects who performed a 1-min sustained handgrip exercise at 50% maximal voluntary contraction followed by forearm occlusion, arterial baroreflex control of MSNA (burst incidence ...
متن کاملCentral mechanisms of acute ANG II modulation of arterial baroreflex control of renal sympathetic nerve activity.
Short-term intravenous infusion of angiotensin II (ANG II) into conscious rabbits reduces the range of renal sympathetic nerve activity (RSNA) by attenuating reflex disinhibition of RSNA. This action of ANG II to attenuate the arterial baroreflex range is exaggerated when ANG II is directed into the vertebral circulation, which suggests a mechanism involving the central nervous system. Because ...
متن کاملPresentation of a Non-invasive Method of Estimating Arterial Stiffness by Modeling Blood Flow and Arterial Wall Based on the Determination of Elastic Module of Arterial Wall
Introduction: Arterial stiffness is an important predictor of cardiovascular risk. Several indices have been introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. Since the substitution of the blood pressure changes in the central arteries such as carotid with the blood pressure changes in the brachial results in error in the blood...
