Abstract: 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.
