Abstract:
Objective To investigate the clinical value of blood vessel diameter tracking and X-strain technology in evaluating the carotid elasticity in patients with diabetes.Methods Thirty-eight patients who were confirmed as diabetes without complications were enrolled in this study as the patient group and thirtyseven healthy volunteers matched with the patient group with sex,ages were typed as controls.The parameters reflecting common carotid elasticity:pulse wave velocity ( PWV),compliance coefficient (CC),stiffness index ( β),endovascular circumferential strain,strain rate,strain time ( EN _ CS,EN _ CS_ T,EN_CSR,EN_CSR_T),adventitial circumferential strain,strain rate,strain time (EP_CS,EP_CS_T,EP_CSR,EP_ CSR_ T),radial strain ( RS),radial strain rate (RSR) and radial strain time (RST) were measured using blood vessel diameter tracking technique and X-strain technique.Significant difference between the two groups and correlations among these variables were evaluated.Results In patient group,PWV and β were significantly higher than those of the control group,while variables like CC,EN_CS,EN_CSR,EP_CS,EP_CSR,RS and RSR were lower with P ＜0.05.All strain time prolonged in patient group ( P ＜0.05).No significant differences were observed in longitudinal strain index.Furthermore,CC was inversely related with PWV( r =- 0.872,P ＜0.001 ),and age,systolic pressure,β were positively related with PWV ( r =0.322,P =0.005; r =0.384,P =0.001; r =0.927,P ＜0.001) in patients group.Conclusions The stiffness and compliance indexes measured by blood vessel diameter tracking technique and the circumferential and radial strain index obtained by X-strain technique can reflect vessel elasticity change of patient with diabetes objectively.
