Reactivity to low‐flow as a potential determinant for brachial artery flow‐mediated vasodilatation
Previous studies have reported a vasoconstrictor response in the radial artery during a cuff-induced low-flow condition, but a similar low-flow condition in the brachial artery results in nonuniform reactivity. This variable reactivity to low-flow influences the subsequent flow-mediated dilatation (FMD) response following cuff-release. However, it is uncertain whether reactivity to low-flow is ...
متن کاملNew monitoring software for larger clinical application of brachial artery flow-mediated vasodilatation measurements.
BACKGROUND The reproducibility of brachial artery flow-mediated vasodilatation (FMD) is limited by the operator dependence of most measurement methods. METHODS A new automated computerized analysis of brachial artery ultrasound scan providing a continuous evolution of the diameter during acute hyperemia, reactive to short hyperemia of the forearm and hand, was tested in 10 normal volunteers a...
متن کاملEvaluation of brachial artery diameter and flow-mediated vasodilatation as tools to predict cardiovascular events in type 2 diabetes patients
Materials and methods In this diagnostic test study, the type 2 diabetic patients were submitted to clinical and laboratory evaluation. Endothelial function was evaluated with Doppler ultrasound of the brachial artery, measuring the basal diameter and the FMD after ischemia in the forearm. ROC curves were constructed and two scores were used as reference standards to assess the risk of having a...
متن کاملImpairment in flow-mediated vasodilatation of the brachial artery in acromegaly.
OBJECTIVE The aim of this study was to assess flow-mediated dilatation (FMD) of the brachial artery in patients with acromegaly. SUBJECTS AND METHODS We prospectively evaluated 25 patients with acromegaly (14 females, 11 males; aged 42 +/- 12 years; growth hormone (GH) levels 34 +/- 14 ng/ml) and 27 control subjects (15 females, 12 males; aged 45 +/- 8 years; GH levels 3 +/- 1.5 ng/ml). The p...
متن کاملAbnormal systolic blood pressure during treadmill test and brachial artery flow-mediated vasodilatation impairment.
The aim of the study was to assess the relationship between systolic blood pressure during maximal treadmill test (SBP9mtt)) and flow-mediated vasodilation (FMD). Abnormal rise of SBP(mtt) is the phenomenon more frequent in hypertensive persons but it could be found in normotensive subjects too. 199 subjects referred to treadmill test were enrolled in the study. Four groups were formed: hyperte...
