摘 要: | 目的:探讨声学密度定量(AD)技术评价风湿性心脏病患者心肌病变的临床意义。方法:应用AD技术对30例风湿性心脏病患者和30例正常对照组左心室长轴切面、心尖四腔心切面和心尖左室两腔心切面中间段、乳头肌水平左室短轴切面心肌的背向散射值进行测量,按不同节段分别比较病例组和对照组的平均图像强度百分比(AII%)、标准偏移(SDI)及心动周期变化幅度(PPI)值。结果:病例组的AII%值较对照组明显增高(P<0.05),PPI值明显减低(P<0.05),SDI与对照组比较差异无统计学意义(P>0.05)。结论:AD技术可以用于评价风湿性心脏病患者的心肌病变,协助判断心肌病变程度。

Abstract: | Objective To investigate tbe clinical significance of acoustic densitometry (AD) technology evaluating myocardium changes in patients with rheumatic heart disease. Method Using AD technique to measure integral backscatter of parastemal left heart long axis view, parastemal papillary muscle level short axis view, apical 4 - chamber view and apical 2 - chamber view in 30 patients with rheumatic heart disease and 30 normal persons, AII% , SDI and PPI were compared. Results SDI of the two groups did not have significant difference. AII% in the rheumatic heart disease group was higher than the control group, PPI was decreased than the control group, and difference was significant( P 〈 0.05 ). Conclusion The acoustic densitometry technology can evaluate the myocardium changes in patients with rheumatic heart disease. |
