Abstract: Objective To assess the value of early evaluation of left ventricular global systolic function in patients with metabolic syndrome(MS) by three-dimensional speckle tracking echocardiography (3D-STI).Methods 33 healthy subjects and 41 MS subjects who didn't have the left ventricular remodeling were recruited in this study,and the myocardial motions were tracking by 3D-STI.The parameters of left ventricular global longitudinal peak systolic strain(LS),circular peak systolic strain(CS),radial peak systolic strain(RS) and area peak systolic strain (AS) and the values of body mass index (BMI),waist circumference,waist-to-hip ratio and biochemical indicators were compared between the two groups.Results Compared with controls,LS of MS group was significantly decreased (P ＜ 0.01),while no significantly differences were found in CS,RS,and AS(P ＞0.05).The BMI,waist circumference and waist-to-hip ratio were positive correlated with LS (r =0.559,0.617,0.681,P ＜0.01).Conclusions 3D-STI could early evaluate the changes of left ventricular global systolic function for metabolic syndrome patients,and longitudinal peak systolic strain could be the most sensitive index.
