Minimum recovery time required between reactive hyperaemia stimulus in the repeated measurement of brachial flow-mediated dilation (FMD)

Assessment of Flow Mediated Dilation (fmd) in Humans:

Reliability of the measurement of the flow-mediated dilation of the brachial artery by ultrasonography.

E-mail: [email protected] Senhor Editor, Lemos com muito interesse o trabalho de Meirelles e cols.1 sobre a confiabilidade da medida da dilatação fluxo-mediada da artéria braquial por meio da ultra-sonografia realizada em 13 voluntários aparentemente saudáveis e não fumantes. Neste trabalho, os autores tiveram o cuidado de utilizar a metodologia padronizada e as recomendações da Internationa...

Can the measurement of brachial artery flow-mediated dilation be applied to the acute exercise model?

The measurement of flow-mediated dilation using high-resolution ultrasound has been utilized extensively in interventional trials evaluating the salutary effect of drugs and lifestyle modifications (i.e. diet or exercise training) on endothelial function; however, until recently researchers have not used flow-mediated dilation to examine the role of a single bout of exercise on vascular functio...

Are the dynamic response characteristics of brachial artery flow-mediated dilation sensitive to the magnitude of increase in shear stimulus?

The purpose of this study was to determine the dynamic characteristics of brachial artery dilation in response to step increases in shear stress [flow-mediated dilation (FMD)]. Brachial artery diameter (BAD) and mean blood velocity (MBV) (Doppler ultrasound) were obtained in 15 healthy subjects. Step increases in MBV at two shear stimulus magnitudes were investigated: large (L; maximal MBV atta...

Local Shear Stress and Brachial Artery Flow–Mediated Dilation

Endothelium-dependent flow-mediated dilation is a homeostatic response to short-term increases in local shear stress. Flow-mediated dilation of the brachial artery in response to postischemic reactive hyperemia is impaired in patients with cardiovascular disease risk factors and may reflect local endothelial dysfunction in the brachial artery. However, previous studies have largely neglected th...
