Abstract: ObjectiveTo assess the value of echo-tracking technology in evaluating endothelial function of the femoral artery in
patients with Grave’s disease.MethodsThirty-four patients with Grave’s disease patients and30normal adults as controls
wererecruitedinthis study. Theintima-mediathickness (IMT), arterial stiffness (β), pressurestrainelasticmodulus (Ep),
arterial compliance(AC), pulsewaveconductingvelocity(PWVβ) andaugmentationindex(AI) parameterswereexamined
using echo-tracking technology for evaluating the right femoral arterial elasticity.ResultsCompared with the control subjects,
thepatientswithGrave’sdiseaseshowedsignificantlyincreasedβ, Ep, andPWVβandsignificantlydecreasedAC(P<0.05), but
the argumentation index were similar between the two groups (P>0.05). Inpatients withGrave’s disease, βandEpwere
positively correlated with FT3, FT4, TT3, TT4, and PWVβ was positively correlated with FT3 and FT4. Conclusion
Echo-tracking technology can provide more accurate quantitative evidences for early diagnosis of femoral artery endothelial
dysfunction in patients with Grave’s disease, but the influence of procedural factors on the measurement accuracy should be
considered in the evaluation.
