Abstract:
Objective To assess the two-dimensional carotid strain as an index of arterial stiffness in patients without carotid atherosclerotic plaques,and its clinic value in cardiovascular risk stratification.Methods All patients were divided into three groups (low risk,intermediate risk,high risk group) by Framingham cardiovascular risk scores,two-dimensional carotid circumferential strain (CS),carotid intimamedia thickness (IMT) were evaluated.CS was adjusted for pulse pressure (CS/PP).Results CS,CS/PP,IMT were significant difference between low risk and intermediate risk groups,low risk and high risk groups (P ＜0.05).IMT and CS were not significant difference between intermediate risk and high risk group (P =0.23,P =0.57).CS/PP was significant difference between three groups (P ＜0.05).Both CS and CS/PP were correlated with IMT (r =-0.30,r =-0.33,P ＜0.05).Conclusions Two dimensional strain could assess the carotid arterial mechanics.IMT and CS could evaluate the structural and functional alternations of carotid stiffness.Combining these two indices allowed more accurate evaluation of the subclinical phase of the atherosclerotic disease.
