目的评价64排CT冠状动脉成像(CTCA)技术诊断冠状动脉显著狭窄(≥50%管腔狭窄)的临床价值.方法采用CTCA对61例临床疑诊冠心病患者进行检查,并于CTCA检查后2周内行选择性冠状动脉造影(SCA).结果 1例患者因冠状动脉严重钙化4支血管CTCA不可评估,其余60例患者240支冠状动脉血管CTCA均可良好显影,240支血管显著狭窄诊断的灵敏度、特异度、阳性预测值及阴性预测值分别为90.0%(72/80)、91.9%(147/160)、84.7%(72/85)、94.8%(147/155).结论 CTCA显示了较高的阴性预测值,可以作为排除冠状动脉显著病变的一种无创标准性检查.

Objective To evaluate the clinical diagnostic value of 64-slice computed tomography coronary angiography (CTCA) for the detection of significant coronary artery stenosis ( ≥50% lumen reduction). Methods We enrolled 61 patients (47 male, 14 female; mean age 62.8 ± 9.7 years) with suspected coronary artery disease into the study and performed selective coronary angiography (SCA) within 2 weeks after CTCA examination. Results One patient was excluded from the analysis because of unsuccessful CTCA evaluation as a result of severe coronary artery calcification in 4 vessels. 240 vessels of remaining 60 patients were achieved good coronary artery imaging by CTCA. Sensitivity,specificity and positive and negative predictive value of CTCA for detecting significant coronary artery sternosis on a per-vessel basis were 90.0 % ,91.9% ,84. 7% and 94.8% ,respectively. Conclusions Our data indicated that 64-slice CTCA is a noninvasive method to reliably rule out significant coronary sternosis with high diagnostic value in negative prediction.
