摘要
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.
