| Objective: To evaluate abdominal obesity and non-abdominal obesity type 2 diabetes mellitus(T2DM)patients left ventricular global systolic function using three-dimensional speckle tracking imaging(3D-STI).Methods: From November 2017 to December 2018,a total of 60 T2 DM patients were enrolled,and divided into T2 DM with abdominal obesity(male WHR≥0.9,female WHR≥0.85)group(30 patients),T2 DM without abdominal Obesity(male WHR<0.9,female WHR<0.85)group(30 patients),30 healthy volunteers were selected as the control group,a Il participants left ventricular ejection fraction(LVEF)was in the normal range(≥55%).The left ventricular apical four-chamber heart full volume images were collected and analyzed in Echopac workstation in order to calculate the left ventricular global longitudinal strain,circumferential strain,area strain,radial strain(LVGLS、LVGCS、LVGAS、LVGRS),left ventricular end-diastolic volume,left ventricular end-systolic volume,left ventricular ejection fraction(LVEDV、LVESV、LVEF)of all participants,the index were compared between the 3 groups.Result: The LVGCS,LVGAS and LVGRS in T2 DM patients without abdominal obesity were lower than those in the control group(P<0.05),and LVGLS was significantly lower than the control group(P<0.001),the difference was statistically significant.The 3D-LVEF of T2 DM with abdominal obesity group was lower than that of the control group(P<0.05),LVGLS,LVGCS,LVGAS and LVGRS were significantly lower than the control group(P<0.001),and LVGCS,LVGAS,LVGRS were lower than T2 DMWith abdominal obesity group(P<0.05),LVGLS was significantly lower than T2 DM without abdominal obesity group(P<0.001),the difference was statistically significant.Conclusion: 3D-STI can be used for early and objective assessment of left ventricular systolic function in patients with normal ejection fraction.Abdominal obesity may cause futher decrease in left ventricular global systolic function in patients with T2 DM. |
