Higher incidence of DM and HTN at old age accounts for left ventricular hypertrophy, loss of control of endothelial dilation and changes in the caliber of stenosed coronary artery due to physiologic vasomotion

Impact of vitamin D supplementation on arterial vasomotion
, stiffness and endothelial biomarkers in chronic kidney disease patients.
Poised to respond to physical and molecular factors in the vasculature, the endothelium modulates the vascular smooth muscle contractile state and, as a result is a critical determinant of vasomotion
and consequently blood flow.
An association between vasomotion
and oxygen extraction.
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.
Under in vivo conditions, vasomotion
of DVR is subject to tubulovascular crosstalk .
In most experimental animals, variation in microvascular blood flow is caused by vasomotion
Type 2: AMI due to supply--demand imbalance and/or abnormalities in cardiac vasomotion
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.
