目的研究糖尿病患者左室功能的改变。方法采用彩色多普勒超声对４２例糖尿病患者和４０例正常人的左室收缩及舒张功能进行测定。结果糖尿病患者左室舒张早期充盈速度明显低于正常人，而左室舒张晚期充盈速度及ＰＶＡ／ＰＶＥ比值明显高于正常人（Ｐ＜０．０１）；糖尿病患者的每搏输出量、每分输出量、射血分数及左室短轴缩短率均明显低于正常人（Ｐ＜０．０１）。结论糖尿病患者易发生心功能障碍，彩色多普勒超声心动图测定左室舒张功能障碍可早期发现糖尿病患者心功能改变。
Objective To study the changes of left ventricular function in diabetic patients. Methods The left ventricular systolic and diastolic function in 42 patients with diabetes mellitus and 40 normal controls were measured by color Doppler ultrasonography. Results The diastolic velocity of left ventricular diastolic velocity in diabetics was significantly lower than that in normal subjects, while the late diastolic velocity of left ventricular diastolic velocity and the ratio of PVA / PVE were significantly higher than those in normal subjects (P <0.01). The stroke volume per minute Output, ejection fraction and left ventricular fractional shortening were significantly lower than normal (P <0.01). Conclusion Diabetic patients are prone to have cardiac dysfunction. Color Doppler echocardiography can be used to detect left ventricular diastolic dysfunction in patients with diabetes.
