High Sodium Intake Differentially Impacts Brachial Artery Flow Mediated Dilation when Evaluated with Reactive Versus Active Hyperemia

Independent of changes in MAP, a HS intake impaired peripheral vascular function when assessed via RH-FMD, which was restored with AO consumption, potentially implicating elevated oxidative stress as a contributor to this dysfunction. However, SS-FMD, evaluated via HG exercise, was not altered by a HS intake or AO consumption. In conclusion, 7-days of a HS intake appears to have disparate effects between the two peripheral vascular function techniques, implicating an inability of HS intake to impact exercise-induced BA dilation.
