Brachial Artery Reactivity
Tidsramme: 12 weeks
|
To demonstrate the impact of omega-three fatty acid intake on BART (Brachial Artery Reactivity Test) at 12 weeks. Brachial artery ultrasound measurements Brachial artery reactivity will be assessed by ultrasound and FMD will be calculated as the change in brachial artery diameter after release of suprasystolic blood pressure cuff inflation. A blood pressure cuff will be inflated on the upper arm to induce increase in blood flow, termed reactive hyperemia, which increases arterial diameter. The change in vessel diameter is determined by high-resolution ultrasound imaging. The endothelium-dependent FMD of the brachial artery is quantified as the maximum percent change in arterial diameter, expressed in units of "% of brachial artery". |
