双源CT对男性冠状动脉粥样硬化性心脏病的诊断价值

摘要

Objective To discuss the value of Dual Resource CT ( DSCT) in diagnosis of coronary atherosclerotic heart disea-ses(CAHD). Methods Both DSCT and selective coronary angiography (CAG) were performed in 105 patients (61 males,44 females) . Results were compared with CAG findings which were regarded as gold standard for detecting CAHD . Results 1184 coronary artery segments could be evaluated by DSCT in all the 105 patients. The sensitivity, specificity, positive predictive value , negative predictive value and diagnose accordance rate of DSCT in detecting significant coronary stenosis were 93. 6% ,95. 1% ,73. 9% ,99. 0% , and 94. 9% in males,while in females were 84.1% ,94.4% ,77. 9% ,96. 2% ,and 92.4% . The analysis demonstrated lower sensitivity and negative predictive value in females compared with those in males (P < 0.05). Conclusions DSCT is a high accurate method in detecting CAHD,which may be preferable for males.%目的 探讨双源 CT(DSCT)对男性和女性冠状动脉粥样硬化性心脏病(coronary atherosclerotic heart disease,CAHD)的诊断价值.方法 入选疑诊为 CAHD 的受检者共 105 例(男 61 例,女 44 例),分别行 DSCT 和选择性冠状动脉造影 (coronary angiography,CAG)检查,以 CAG 为诊断 CAHD 的金标准,评估检查结果.结果 105 例受检者中,DSCT 共显示 1184 个冠状动脉节段可进行评价.DSCT 诊断男性受检者冠状动脉显著狭窄的敏感性为 93.6%,特异性为 95.1%,阳性预测值为 73.9%,阴性预测值为 99.0%,诊断符合率为 94.9% ;诊断女性受检者冠状动脉显著狭窄的敏感性为 84.1%,特异性为 94.4%,阳性预测值为 77.9%,阴性预测值为 96.2%,诊断符合率为 92.4%.女性受检者接受 DSCT 检查诊断冠状动脉显著狭窄 的敏感性和阴性预测值低于男性(P ＜0.05).结论 DSCT 在显示冠状动脉病变时具有较高的诊断准确率,尤其适用于男 性.
