| 目的 探讨声学密度定量(AD) 技术在定量评价缺血、梗塞后心肌损害方面的临床价值。方法 对70 例
冠心病患者(AD1 分为缺血组与梗塞组) 及30 例正常人(正常组) 相应部位心肌及左室腔血液密度值进行测定。结果
与正常心肌比较,缺血区与梗塞区心肌AII 值明显增大;与正常组比较,缺血组室间隔( IVS) AII 值略增大;梗塞组
室间隔AII 值明显增大( P < 0105) ;三组二尖瓣环部(MVA) AII 值无显著差异,三组相同切面左室腔血液AII 值无
显著差异,无统计意义。结论 缺血及梗塞心肌的组织密度增高;心肌梗塞后不仅只存在梗塞部位心肌组织密度的
改变,还存在室间隔心肌组织密度的改变。AD 技术能客观反映缺血、梗塞后心肌组织特性的变化,对鉴别心肌病变
具有一定的诊断意义。 |

| Objective To evaluate the value of Acoustic Densitomitry (AD) techeniuque in detecting myocardial damage
secondary to ischemia and infarct . Methods 70 cases with coronary artery disease (CAD and 30 normals were involved in
this study. Results The values of AII of ischemic and infarcted myocardium were higher than normal. The infarcted patients densitometry values of IVS increased obviously ,but little difference of MVA in the three groups. and no significant
difference of the blood in left ventricle in same view in the three groups. Conclusion Acoutstic Densitometry can detect the
changes of tissue characterization in ischemic and infarcted myocardium. It is useful in identification of myocardial disease. |
