摘要
目的:探讨电子束CT(EBCT)检测确定的冠状动脉钙化(CAC)诊断冠心病的价值.方法:同期行EBCT和ECG检查的临床怀疑或确诊的冠心病患者420例,其中:同期行超声心动图(UCG)检查195例,作选择性冠状动脉造影56例,作3种检查的有38例.结果:CAC率和积分(SC)在ECG、UCG各组中差异均有显著性(P＜0.01～＜0.001).CAC、CS在冠脉造影显示的不同狭窄程度与病变支数各组中有显著差异(P＜0.05～＜0.01).CAC诊断的敏感性、特异性和准确分别达到79.3%、74.1%、76.8%,均显著高于ECG、UCG组(P＜0.05).结论:EBCT检测的CAC诊断冠心病的准确性等指标高于ECG、UCG法.
Objective: To investigate the diagnostic value of coronary artery calcification (CAC) determined by electron bean computed (EBCT) in diagnosis of coronary artery disease. Methods: Four hundred and twenty patients underwent EBCT and ECG examines in same time, in which 195 cases also underwent echocardiography (UCG), 56 patients underwent coronary angiography (CAG). EBCT、 ECG and UCG were performed in 38 cases in same time. Results: The CAC incidence and scores significantly increased (P<0. 01 - <0. 001) in abnormal groups of ECG and UCG. CAC incidence and scores increased (P<0. 05- <0. 01) according coronary artery narrow degree and the number of pathological vessel. The sensitivity、 specificity and accuracy of CAC were 79.3%、 74.1%、 76.8% respectively, it were higher than those of ECG and UCG (P<0. 05). Conclusion: Diagnostic accuracy etc of CAC for coronary artery disease is higher than those of ECG and UCG.
