摘要
目的 探讨超声三维斑点追踪技术早期评价代谢综合征患者左室整体收缩功能的价值.方法 使用超声三维斑点追踪技术对33例正常人和41例尚未发生左室重构的代谢综合征患者（MS组）进行心肌运动分析,测量左室整体的收缩期峰值纵向应变（LS）、圆周应变（CS）、径向应变（RS）及面积应变（AS）,并采集两组体质量指数（BMI）、腰围、腰臀比以及生化指标,比较两组上述参数.结果 与对照组比较,MS组的LS绝对值减低（P＜0.01）；两组间的CS、RS及AS差异均无统计学意义（P＞0.05）；LS与所有研究对象的BMI、腰围、腰臀比呈正相关,相关系数分别为0.559、0.617、0.681（P＜0.01）.结论 超声三维斑点追踪技术可早期评价代谢综合征患者左室整体收缩功能的改变,纵向应变是较敏感的评价指标.
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.
