摘　　要：目的:评价2型糖尿病和糖耐量异常对原发性高血压患者左心室收缩功能的影响。方法:92例原发性高血压患者[(52±13)岁],其中合并2型糖尿病者25例、合并糖耐量异常者27例,行常规超声和组织多普勒成像组织追踪(TT)检查。结果:合并2型糖尿病或糖耐量异常患者的常规超声心动图(ECH O)左室收缩功能指标与单纯原发性高血压患者的差异无显著性。合并2型糖尿病患者各节段的TT值均比合并糖耐量异常和单纯原发性高血压患者为小,合并糖耐量异常患者和单纯原发性高血压患者相比差异无显著性。结论:在常规方法显示左室收缩功能正常的原发性高血压患者中,超声TT技术提示合并2型糖尿病患者的左室收缩功能已明显降低。Objective To evaluate the influnence of diabetes mellitus (DM) and impared glucose tolerance (IGT) to the left ventricular contractility in essential hypertensive patients. Methods The cardiac geometry and function was assessed by echocardiography and tissue tracking (TT) of tissue Doppler imaging (TDI) in 92 essential hypertensive patients[(52±13) years old] including 25 patients with DM and 27 patients with IGT. Results There was no signifigant difference in the left ventricular systolic function by conventional echocardiography between hypertensive patients with DM or IGT and isolated essential hypertensive patients. TT of all segments decreased more in DM patients than in IGT patients and isolated hypertensive patients. There was no difference in TT between IGT patients and isolated hypertensive patients. Conclusions Among the essential hypertensive patients with normal systolic function assessed by conventional echocardiography, TT echocardiography shows the cardiac contractility decreases in the hypersensitive patients complicated with DM.
