regulatory changes leading to abnormal vasomotion and the expression of a prothrombotic and pro-inflammatory phenotype of the vascular endothelium.
If it is assumed that there is no vasomotion in the area, the summed velocity data will be equal to the blood flow.
In addition, a subset of patients within the trial will be evaluated for novel endpoints such as vasomotion, a measure of how much natural motion returns to the vessel as Absorb dissolves into the arterial tissue.
In most experimental animals, variation in microvascular blood flow is caused by vasomotion (134).
Accumulating data suggest that the degree of impairment of endothelium-dependent vasomotion has profound and independent prognostic implications.
In a subset of 45 patients, state-of-the-art imaging techniques showed improvements in vasomotion (vessel movement) and a 7.
Type 2: AMI due to supply--demand imbalance and/or abnormalities in cardiac vasomotion and/or dissection.
However, permanent metallic stenting could preclude surgical revascularization, and jail-side branches prevent expansive remodeling, eliminate reactive vasomotion, and impair the noninvasive imaging of coronary arteries with multislice X-ray computed tomography (CT) and magnetic resonance imaging (MRI) (12).
The primary endpoints of the trial are change in dimension of the lumen (interior of the vessel) over time and vasomotion (vessel movement) at the treated vessel segment, which will be assessed based on changes in the vessel diameter in response to a stimulus.
Meanwhile, isolated vascular ring test indicated that TFY had an significant effect on vasomotion, and antagonize vasospasm; moreover TFY also could increase cerebral blood flow (CBF) and reduce cerebrovascular resistance index (RI) in normal rabbits, which verified the effect of TFY on vasomotion and abnormal hemorheology.
