摘要
目的应用多普勒组织成像(DTI)技术评价2型糖尿病患者左室功能;探讨高血压对糖尿病心脏结构和功能的影响。方法应用超声心动图诊断仪检测糖尿病患者、糖尿病合并高血压患者左心室DTI频谱,测量Sa、Ea、Aa与Ea/Aa,并与30例正常人做对照。结果两组糖尿病患者Aa与对照组比较有显著性差异,糖尿病合并高血压组与正常血压糖尿病组Sa、Ea比较有显著降低。结论组织多普勒技术可以早期无创评价糖尿病患者心脏的收缩和舒张功能,高血压加重糖尿病患者心脏结构和功能的损害。
Objective To evaluate the left ventricular function in nomaltensive and hypertensive patients with type 2 diabetes by Doppler tissue imaging （DTI） and survey the effectiveness of secondary hypertension on the left ventrlcular structure and function in patients with type 2 diabetes. Methods Forty five patients with type 2 diabetes and 30 cases of healthy control were divided into three groups： DM, DM＋ HP and healthy. Echocardiography was used to evaluate the left ventricular structure and functional. Sa, Ea, Aa and Ea/Aawere measured and compared among healthy group, DM and DM ＋ HP groups. Results Aa in group DM and DM＋HP were higher than that in healthy group, especially in group DM＋HP. Ea in group DM and DM＋HP were lower than those in healthy group. Sa in DM＋ HP was lower than in DM and healthy group. Conclusion DTI can be used to evaluate the left ventricular systolic and diastolic function in patients with type 2 diabetes early and noninvasively. Hypertension aggravates the structure and function of left ventricle in patients with type 2 diabetes.
