The clinical value of 64-slice CT angiography in the diagnosis of coronary artery stenosis

Abstract

Objective To discuss the clinical value of 64-slice CT angiography in the diagnosis of coronary artery stenosis.Methods 60 patients with suspected coronary artery disease were examined by CAG and 64SCT,then we contrasted the results,and diagnostic value of 64SCT in coronary artery stenosis was tested by CAG as the gold standard.Results The number of coronary section could clearly show in 64SCT(458) were significantly more than in the CAG(504)(x2 =20.1318,P＜0.01) ;but there was no significant difference in the diagnosis rates of coronary heart disease between the two methods (P ＞0.05) ;the sensitivity of 64SCT in coronary artery disease was 93.4％,specificity 96.0％,positive predictive value of 88.0％,and negative predictive value of 97.9％.Conclusion Compared with CAG deficiencies in the diagnosis of coronary artery stenosis,64SCT has higher value.,and it has high sensitivity,specificity,positive and negative predictive value in the diagnosis of coronary artery stenosis,and which is worthy of early screening for the disease.
