目的评价组织速度成像技术在检测糖尿病患者早期心脏功能改变的应用价值。方法选取无高血压、冠心病及其他心脏病变的糖尿病患者36例,健康人32例(正常对照组),比较两组间的常规超声指标EF值、E/A;组织速度指标VS、VE、VA以及VE/VA,分析EF与VS的相关性以及E/A与VE/VA的一致性。结果糖尿病组与健康组比较,EF值、VS、VA差别无显著性(P<0.05),而糖尿病组VE绝对值、VE/VA较正常对照组显著降低(P<0.05)。结论二尖瓣口血流E/A以及室间隔组织速度成像VE/VA可反映糖尿病患者早期心脏舒张功能的改变。
Objective To evaluate the value of tissue velocity imaging in the detection of early cardiac function in diabetic patients. Methods 36 cases of diabetic patients without hypertension, coronary heart disease and other heart diseases and 32 healthy people (control group) were enrolled in this study. The EF, E / A, VA and VE / VA, the correlation between EF and VS and the consistency between E / A and VE / VA were analyzed. Results There was no significant difference in EF, VS and VA between diabetic group and healthy group (P <0.05), while the absolute value of VE and VE / VA in diabetic group were significantly lower than those in normal control group (P <0.05). Conclusion Mitral mitral flow E / A and ventricular septal tissue velocity imaging VE / VA can reflect the changes of early diastolic function in diabetic patients.
