文摘目的应用二维斑点追踪技术评价2型糖尿病患者左心室心肌纵向收缩功能早期改变。方法选取2型糖尿病患者60例(T 2DM组)及正常对照组60例,应用经胸二维超声、获取受检者心尖二腔观、三腔观、四腔观图像,记录左心室内膜及外膜心肌纵向收缩期峰值应变。结果 T 2DM组与正常对照组各常规超声心动图参数(左心室收缩末期内径、左心室舒张末期内径、左心室后壁舒张末期厚度、室间隔舒张末期厚度、左心室射血分数、左心室内径缩短率、左心室质量及左心室质量指数)差异均无统计学意义;与正常对照组比较,T 2DM组的左心室长轴内膜心肌纵向峰值应变均明显减低(P<0.05),而外膜心肌只有后壁、下壁及后间隔纵向峰值应变明显减低(P<0.05)。结论二维超声斑点追踪技术能发现常规超声心动图难以发现的糖尿病患者左心室早期心肌纵向收缩功能异常。
