摘要
目的探讨应用三维斑点追踪技术评价糖尿病足患者左室功能的临床价值。方法选择我院内分泌科糖尿病患者49例,分为单纯糖尿病组27例和糖尿病足组22例(Wagner分级为0~2级),另选与其年龄、性别相匹配的健康志愿者29例为正常对照组。均于心尖四腔观获取动态三维左室模型,应用三维斑点追踪技术测量各组左室整体纵向、径向及圆周收缩期峰值应变(GLS、GRS、GCS),并比较其差异。结果单纯糖尿病组和糖尿病足组GLS、GCS、GRS与正常对照组比较,差异均有统计学意义(均P<0.05)。糖尿病足组GLS、GCS、GRS值均较单纯糖尿病组下降,差异均有统计学意义(均P<0.05)。结论应用三维斑点追踪技术可早期发现糖尿病患者心肌亚临床损害,其中糖尿病足患者左室心肌整体应变能力下降更为显著,为早期进行临床干预提供了依据。
Objective To explore the of clinical value of three-dimensional speckle tracking imaging(3D-STI)in evaluating the left ventricular function in patients with diabetic foot.Methods A total of 49 diabetes patients admitted to endocrinology department in our hospital were selected,they were divided into 27 cases as simple diabetic group and 22 cases as diabetic foot group(Wagner grade was 0~2).In addition,29 healthy volunteers with matched age and sex were selected as normal control group.From apical four chamber view,used 3D-STI to measure overall longitudinal,radial and circular shrinkage peak strain(GLS,GRS,GCS)in left chamber of each group,and compared differences between the three parameters.Results Compared with normal control group,there were statistical differences in GLS,GCS and GRS values of diabetes group and diabetic foot group(all P<0.05).Compared with diabetes group,the GLS,GCS,GRS values of diabetes foot group decreased,and there were statistical differences(all P<0.05).Conclusion 3D-STI can be used to detect subclinical myocardial damages in patients with diabetes mellitus,and the left ventricular strain capacity in patients with diabetic foot decreased significantly.So 3D-STI technology can provide a basis for early clinical intervention.
