| 摘 要： | 目的 分析零冠状动脉钙化积分(CACS)患者64层冠状动脉CTA(CTCA)表现,并评估诊断准确率。 方法 对328例零CACS的疑似冠心病患者,分析CTCA表现,包括有无狭窄、斑块形态、位置和狭窄程度。其中69例有传统冠状动脉造影结果,计算零CACS患者CTCA诊断狭窄≥70%的敏感度、特异度、准确度、阳性预测值和阴性预测值。 结果 328例零CACS患者,CTCA示37例(37/328,11.28%)存在不同程度的狭窄和斑块,无或轻度狭窄26例(26/37,70.27%),中度狭窄8例(8/37,21.62%),重度狭窄3例(3/37,8.11%)。54个狭窄斑块包括软斑块39个(39/54,72.22%)、混合斑块8个(8/54,14.81%)及7个钙化斑块(7/54,12.96%)。基于病例(69例)和基于冠状动脉节段(997个节段)CTCA诊断狭窄≥70%的敏感度、特异度、准确率、阳性预测值和阴性预测值分别为97.14%(34/35)、94.12%(32/34)、95.65%(66/69)、94.44%(34/36)、96.97%(32/33)和94.23%(49/52)、99.58%(941/945)、99.30%(990/997)、92.45%(49/53)、99.68%(941/944)。 结论 CTCA可显示零CACS患者冠状动脉的不同程度狭窄和斑块,且诊断准确度较高。

| Abstract: | Objective To evaluate the findings and the diagnostic accuracy of 64-slice CT coronary angiography(CTCA) for the detection of significant coronary artery stenosis in patients with zero coronary calcium score(CACS).Methods Totally 328 patients with suspected coronary artery disease with a zero CACS were retrospectively identified.CTCA studies were assessed for the presence,morphology,location and severity of all coronary plaques.Compared to conventional coronary angiography,the sensitivity,specificity,accura... |
