摘要
目的探讨声学密度定量分析(AD)技术在评价肝硬化患者心肌损害方面的价值。材料和方法对35例晚期肝硬化患者和30例正常人的室间隔和左室后壁的心肌的声学密度进行测定,同时测定心脏左室大小和室壁厚度。结果晚期肝硬化患者的左室大小和室壁厚度与正常对照组相比无显著性差异,但室间隔和左室后壁心肌的声学密度定量分析校正参数(IBS%)低于正常对照组(P<0.05);两组比较,室间隔和左室后壁的PPI及SDI参数无显著性差异。结论晚期肝硬化患者的心肌存在可以应用AD技术进行评价的病理性改变。
Purpose： Ultrasonographic Acoustic Densitometry （AD） technology was used to assess the changes of myocardial structure in cirrhotic patients. Materials and Methods- 35 patients with end - stage hepatic cirrhosis and 30 normal persons of corresponding ages underwent echocardio- graphy AD assessment based on the Integrated Back Scatter of the structural changes at interseptem and posterior wall. Results： There was no difference in the left ventricular diameter, the thickness of interseptum and posterior wall between cirrhotic and control group. But the AD index （IBS%） of cirrhotic patients was lower than those of the control （ P 〈 0.05）, and there was no difference on PPI and SDI index between the 2 groups. Conclusion： The AD index is a new parameter in assessing pathological change of myocardium in end - stedge cirrhotic patients.
