- W2375595251 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,accuracy,positive and negative predictive value of CTCA in diagnosing stenosis ≥70% were calculated in 69 patients.Results CTCA showed different stenosis and plaques in 37 of 328 patients with a zero CACS(37/328,11.28%).Normal or mild stenosis was presented in 26(26/37,70.27%) patients,moderate stenosis in 8(8/37,21.62%) and severe stenosis in 3(3/37,8.11%).Among the 54 plaques,39(39/54,72.22%) were identified as non-calcified,8(8/54,14.81%) were of mixed morphology,and 7(7/54,12.96%) were calcified.The sensitivity,specificity,accuracy rate,positive and negative predictive value of CTCA on the patient level was 97.14%(34/35),94.12%(32/34),95.65%(66/69),94.44%(34/36) and 96.97%(32/33) respectively,while on the segment level was 94.23%(49/52),99.58%(941/945),99.30%(990/997),92.45%(49/53) and 99.68%(941/944),respectively.Conclusion CTCA can display different coronary stenosis and plaques in patients without coronary calcification with high accuracy rate." @default.
