Congestive heart failure is associated with a reduction in limb venous
volume at an effective venous pressure of 30 mm Hg (VV[30]). Further, an
attenuated arteriolar dilation in response to a metabolic stimulus has been
demonstrated. It was the purpose of this study to determine to what extent
the chronic elevation in venous pressure seen in heart failure might
explain these abnormalities of the limb circulation. Ten normal human
volunteers were subjected to venous congestion of one arm for three hours
at 70 mm Hg. A mercury-in-rubber strain gauge plethysmograph was used to
measure forearm VV [30] and forearm blood flow at rest after release of
five minutes of arterial occlusion (the reactive hyperemia response).
Congestion reduced VV [30] 22%, resting forearm blood flow 49% and peak
reactive hyperemia blood flow 25%. Thus, chronic venous congestion per se
may significantly reduce limb venous volume as well as resting and reactive
hyperemia blood flow.
