核素及X线左室造影定量左室功能对冠心病诊断相关性的初步研究

A Correlation Study of Quantitative Analysis of Left Ventricular Functions of CAD by Radionuclography Comparing with Cineangiocardiography

本文采用核素心室造影(RNV)分析了冠心病组21例的左心整体及局部功能,同时以X线左室造影(CINE)做对照,旨在探讨RNV对冠心病诊断价值。结果发现:用CINE及RNV测得的射血分效及短轴(半径)缩短率进行相关性分析,结果为高度相关(γ分别为0.86及0.84,<0.0001);其中EF的敏感性为91%,特异性为90%。说明RNV的EF指标是公认的评价收缩功能的可靠指标之一,TRS是定量诊断RWMA的可靠指标之一,它们能敏感及特异的反映CAD患者左室收缩功能的变化及局部室壁运动失常,故在一定程度上可代替CINE。

In order to assess the value of diagnosing coronary artery disease (CAD) with radionuclide ventriculography (RNV), the methods of quantitaive analysis of left ventricular global and regional functions by RNV comparing with cineangiocardiography (CINE) were studied. Results: EF and TRS of RNV were well correlated inversely with EF and %△a of CINE(r was 0.86 and 0.84 respectively, P<0.0001). The sensitivity and specificity of EF were 91% and 90% respectively. It is indicated that RNV is an acceptable method to assess both global and regional functions of LV. EF and TRS are sensitive and specifical indexes fere luating LV global and regional function. It can be used as a new method for quantitatiue analysis of left ventricular functions.
