Application value ofultrasound tracking of mitral annular displacement in evaluating the left ventricular function in patient with type 2 diabetes mellitus

Objective:To evaluate the application value ofultrasound tracking of mitral annular displacement(TMAD) in evaluating the left ventricular function in patient with type 2 diabetes mellitus(T2DM).Methods:Twenty-seven T2DM patients and 27 healthy volunteers were investigated.The high quantity two dimensional gray scale imaging of three consecutive cardiac cycles was obtained using the echocardiography.The systolic peak displacement(Ds),maximum displacement of the midpoint of the annulus(Mid) and maximum longitudinal diameter ratio of left ventricular end diastolic diameter(Mid%) at 4 sites of mitral annulus were measured using TMAD software,and the means value of which was calculated.The LVEF was measured using real time three dimensional echocardiography,and the correlation of the parameters of TMDA(Ds,Mid and Mid%) with two/three-dimensional? image LVEF were analyzed.Results:The differences of the E peak/A peak,ratio of E/A,left ventricular end-diastolic volume,end-systolic volume and LVEF between two groups were not statistically significant(P>0.05).The Ds,Mid and Mid% value in T2DM group were lower than those in control group(P<0.05 to P<0.01).The means value of Ds,Mid and Mid% in two groups were positive correlation with two/three-dimensional LVEF(P<0.05).Conclusions:TMAD)technique can be used to evaluate the left ventricular function in patients with T2DM.
