Velocity Vector Imaging In Essential Hypertensive Patients With Abdominal Aorta Mechanical Motion State

AimTo analyze the elasticity and movement of abdominal aorta wall of patients with essential hypertension with velocity vector imaging(ⅤⅥ).MethodsTwo dimensional dynamic images of 120 patients with essential hypertension (hypertension group, including 60 normal blood pressure after standard treatment and 60 not normal blood pressure after standard treatment) and 60 normal people (control group) were obtained in short-axis view with color Doppler ultrasound. The ⅤⅥ technology has been used to analyze the maximum radial velocity (Vmax), the maximum tangential strain (Smax) and the maximum tangential strain rate (SRmax) of abdominal aorta wall, including 6 segments: Anterior wall, anterointeral wall, posterointeral wall, posterior wall, posterolateral wall and anterolateral wall.ResultsThe Vmax, Smax, SRmax of the hypertension group is lower than the control group (P<0.05). The Vmax of the hypertension group has no statistical significance (P>0.05). The Smax and SRmax of the not normal blood pressure after standard treatment is lower than those of the normal blood pressure after standard treatment (P<0.05).ConclusionⅤⅥ technique not only can quantitative analyze Vmax, Smax, SRmax of abdominal aorta wall of patients with essential hypertension, but also detect the structure and function of abdominal aorta before damaged. Results obtained showed that it is a simple and accurate method for evaluating the elasticity of abdominal aorta of patients with essential hypertension.
