Clinical application of E-tracking technique in T2DM patients common femoral artery elastidties / 中国综合临床

ABSTRACT

Objective To study the elastic features of common femoral artery by echo-tracking(ET)technique in type 2 diabetic(T2DM)patients.Method 60 eases of T2DM and 60 cases in control group,were separated into groups with age,ET technique was used to evaluate the common femoral artery modulus,including pressure strain elastic modulus(Ep),stiffness parameter(β),arterial compliance (AC),augment index(AI).Results Compared with the normal group ,in the T2DM group,β and Ep of common femoral artery were significantly higher(P＜0.01,P＜0.05),and AC was significantly lower(P＜0.05),and the difference in AI was not obvious (P＞0.05).The indexes were most obviouse in 40 to 59-year-old.The correlation parameter of age with β,Ep,AC,AI was 0.74,0.76 (P＜0.001)and 0.62,0.51 (P＞0.05).Conclusion The elasticity declination of common femoral artery in T2DM patients occur in the early stages,the change in 40-59 years old is obvious.β,Ep are apparently age-related indexes,and AC,AI are not.
