摘要:
目的:评价电子束CT冠状动脉血管成像技术(EBT)在老年男性冠心病患者的诊断价值.方法:对48例临床有冠心病症状、可疑冠心病症状或无症状的老年男性，进行EBT及冠脉造影(CAG)检查，以CAG结果作为“金标准”评价EBT与冠脉狭窄之间的相关性.结果:①冠状动脉狭窄组的EBT阳性率明显高于非狭窄组(P<0.01)，两种方法的检测结果并无统计学差异(P>0.05).② EBT诊断冠脉狭窄的灵敏度、特异度、误诊率、漏诊率、准确度、阳性预告值、阴性预告值、阳性似然比及阴性似然比分别为86%,67%,33%,14%,83%,95%,40%,2.6及0.21。③EBT阳性与冠脉存在狭窄血管支数之间呈正相关。④EBT对于冠脉近段血管狭窄诊断的敏感性、特异性、准确性均较高，而对远段血管的诊断则与CAG相差较大。结论:① EBT是预测老年冠心病的有价值的检查手段。②EBT对于冠脉近段病变具体位I的确定有价值。
Abstract:
AIM:To evaluate the value of eletron-beam computed tomographic angiography(EBT) in the diagnosis of coronary artery disease (CAD) in the elderly man, METHODS:Fourty-eight elderly men underwent EBT and CAG. Results were analyzed with CAG to get the correlaton between EBT(+) and stenosis of coronary artery, RESULTS:T The rates of EBT(+) in patients with significant coronary stenosis were much higher than those without stenosis (P<0.01).There was no statistics difference between EBT and CAG(P>O.05)。② The sensitivity,specificity,mistaken diagnosticrate,omission diagnosticrate,accuracy,positive predictive value,negative predictive value，positive likelihood ratio and negative likelihood ratio for EBT to predict CAD were86%,67%,33%,14%,83%,95%,40%,2.6 and 0.21.③ There was apositive relation between the number of vessels with coronary stenosis and EBT(+).The sensitivity,specificity and accuracy for coronary stenosis of wide artery diagnosised by EBT were more accurate than those of tiny artery. CONCLUSION:① EBT is helpful in the prediction of coronary artery disease in the elderly man with an accepted accuracy;② EBT is helpful in the prediction of position of proximal coronary stenosis in the elderly man.
