彩色多普勒超声对高血压患者左心室功能评价研究

摘要

Objective To evaluate tje diagnostic Significance of color Doppler ultrasound( CDU)for left ventricle cjange in patients witj jypertension. Method Tje CDU was used to monitor tje blood flow of tje jeart in 22 patients witj jypertension and 20 normal con-trols. End-diastolic volume( EDV),end- systolic volume( ESV),left ventricular ejection fraction( LVEF),E/A ratio,E peak and A peak were calculated. Results Compared witj control group, EDV and ESV increased, LVEF decreased, and E/A ratio in-creased. Conclusion Tje CDU is jelpful for evaluating tje jeart structure and function,wjicj can be jelpful for prevention and treatment of jeart failure in patients witj jypertension.%目的：评价彩色多普勒超声对高血压左心室肥厚患者心脏改变的诊断意义。方法：应用彩色多普勒超声探测22例高血压患者及20例正常者的左室舒张末期内径、左室收缩末期内径、左室射血分数、E/A 比值、舒张早期峰值流速和舒张晚期峰值流速情况。结果：与对照组相比，病例组的左室舒张末期内径、左室收缩末期内径增大，左室射血分数减少，左房室瓣舒张早期血流频谱E峰与左房室瓣环舒张早期运动速度A 峰的比值（ E/A）增大。结论：彩色多普勒超声可了解高血压患者心脏结构、功能，为心力衰竭的预防和治疗提供重要指导依据。
