| 【】目的：探究超声斑点追踪技术评价糖尿病肾功不全左心室收缩功能的价值。方法：选取2015年3月-2016年10月间我院内分泌科住院的50例因糖尿病导致肾功能不全的患者作为观察组,同期选取健康体检的50例志愿者作为对照组,均行肾功能检测、常规超声检查及超声斑点追踪成像,统计并比较常规超声参数及左心室长轴及短轴的心内、外膜层心肌收缩期纵向、径向峰值应变值。结果：与对照组比较,观察组患者内生肌酐清除率显著降低,BUN、NPN、血清肌酐水平显著升高(P<0.05)；两组IVSTd、PWTd、LVDd、LVDs、LVEF等超声参数间差异无统计学意义(P>0.05),观察组患者E/A及Em/Am较对照组显著减小(P <0.05)；对照组基底段、中间段、心尖段三节段及整体的心内膜层纵向应变值较心外膜层显著升高(P<0.05),观察组各节段及整体的心内膜层、心外膜层纵向收缩期峰值应变值间差异无统计学意义(P>0.05),观察组患者各节段及整体的心内膜层、心外膜层纵向收缩期峰值应变值较对照组均显著降低(P<0.05)；对照组二尖瓣、乳头肌、心尖水平及整体的心内膜层径向收缩期峰值应变值较心外膜层显著升高(P<0.05),观察组各水平及整体的心内膜层、心外膜层径向收缩期峰值应变值间差异无统计学意义(P>0.05),观察组患者各水平及整体的心内膜层、心外膜层径向收缩期峰值应变值较对照组均显著升高(P<0.05)。结论：超声斑点追踪技术可有效评估糖尿病肾功能不全患者左心室收缩功能变化,可作为糖尿病肾功能不全心肌病变早期诊断的重要手段。 |

| Abstract: |
| Objective: To evaluate the value of speckle tracking technique in the evaluation of left ventricular systolic function in diabetic renal insufficiency. Methods: 50 patients with renal dysfunction caused by diabetes mellitus in our department of Endocrinology from March 2015 to October -2016 were selected as the observation group. Meanwhile, 50 volunteers in our hospital were selected as the control group. The two groups underwent renal function detection, conventional ultrasound detection and ultrasound speckle tracking, the conventional echocardiographic parameters and left ventricular long axis and short axis of the heart of the inner and outer layer of longitudinal and radial systolic peak strain value were statisticed and compared. |
