高血压心肌肥厚与非心肌肥厚患者心肌声学密度定量检测

Comparison of the myocardial acoustic densitometry between hypertension with and without ventricular hypertrophy

目的:评价高血压心肌肥厚的心肌组织特征。方法:应用PHLIPSiE33型超声显像仪对高血压心肌肥厚患者(A组)、高血压非心肌肥厚患者(B组)及正常健康人群(C组)进行心肌声学密度检测,感兴趣区定量分析(ROI),观察AII、PPI和AII%。结果:高血压非心肌肥厚患者和正常健康人群的室间隔及左室后壁的AII、PPI和AII%差异无统计学意义(P>0.05);高血压心肌肥厚患者的AII和AII%显著高于其他两组,而PPI显著低于其他两组,差异均具有统计学意义(P<0.05)。结论:声学定量技术能反应高血压心脏病患者的心肌组织特征,对心肌异常具有诊断价值。

Objective：To evaluate the features of myocardium in patients with hypertension.Methods：PHILIPS iE33 ultrasonicsterm was used to analyze the AII,PPI,and AII% in the three groups of hypertension with ventricular hypertrophy（A group）,hypertension without ventricular hypertrophy（B group）,and healthy people（C group）.Results：The parameters of average image intensity（AII,AII%,PPI） in IVS,LVPW of B and C groups produced no significant difference（P 0.05） ;But there were great changes in B group,where a significant difference was showed compared with the other two groups（P 0.05）.Conclusion：ROI can detect the myocardial changes in patients with hypertension,and it is useful in identification of abnormal myocardium.
