Evaluation Of Carotid Elasticity Function In Fatty Liver Patients By Echo-tracking Technique

Objective To evaluation the carotid elasticity function in fatty liver patients by Echo-tracking technique.Methods Seventy-eight patients with uniformity fatty liver were enrolled in this study as fatty liver group, they were divided into mild, mediate and severe group according to their total of scores. At the same time, forty same period healthy subjects were selected as normal group. The carotid elasticity parameters of each group were measured by ET technique, then the results was compared.Results1. No significant difference among the group with age and gender(P>0.05).2. The difference of carotid elasticity function between left and right carotid was not statistical significant in normal, mild, mediate and severe fatty liver patients group(P>0.05).3. Compared with normal group, stiffness parameters (β), pressure-strain modulus (Ep), pulse wave velocity (PWVβ) in mild, mediate and severe group were increased,artery compliance (AC) was decreased, there were significant difference (P＜0.05), systolic diameter(Ds) and diastolic diameter(Dd) of each group showed no significant difference(P>0.05).4. Compared with mild and mediate group, β, Ep, PWVβ in sever group were increased, AC was decreased, there were significant difference (P＜0.05), Ds and Dd of each group showed no significant difference(P>0.05). While there was no significant difference between mild and mediate group.Conclusions1. Stiffness parameters (β), pressure-strain modulus (Ep), pulse wave velocity (PWVβ) in fatty liver group were higher than the normal group,artery compliance (AC) was lower than the normal group. So, carotid elasticity function in fatty liver patients was lower than normal group.2. Before arterial wall morphological changes, endothelial cell function have changed, namely the artery elasticity function have changed.3. Echo-tracking can be used to early access carotid elasticity function in fatty liver patients. So, can be achieved the purposes of early prevention, early diagnosis and early treatment.
