摘　　要： 目的探讨对冠心病患者采用64排螺旋CT冠状动脉成像技术(64 SCTCA)检查的诊断效果。方法选取2015年7月—2016年7月该院心内科收治的88例高度怀疑为冠心病对的患者进行观察,以选择性冠脉造影(CAG)检查结果作为疾病诊断的金标准,对患者进行CAG、64 SCTCA检查,观察两种检查方法对冠心病准确诊断率、冠脉狭窄部位及程度检出情况。结果 CAG检出阳性病例共75例,阴性病例13例;64 SCTCA检出阳性73例,阴性15例。与CAG检查结果对比差异无统计学意义(P>0.05)。2种检查方法对冠脉狭窄程度检出方面无统计学意义(P>0.05)。CAG检出共有108支血管出现血管狭窄,64 SCTCA对左主干、左前降支的血管狭窄检出高,但是对右回旋支、右冠的血管狭窄检出率明显低于CAG,差异有统计学意义(P<0.05)。结论 64 SCTCA对冠心病的诊断准确率高,图像分辨率高,对冠心病的诊断及疾病监测具有重要作用。 Objective To discuss the effect of 64-slice computed tomography coronary artery angiography in diagnosis of patients with coronary heart disease. Methods 88 cases of patients highly suspected with contrary heart disease in our department from July 2015 to July 2016 were selected and the CAG examination results were used as the golden standards of disease diagnosis, and the patients were examined by the CAG and 64 SCTCA, and the accurate rate in diagnosis of coronary heart disease and test of coronary artery stenosis and degree of the two examination methods were observed. Results The CAG showed that there were 75 positive cases and 13 negative cases, and 64 SCTCA showed that there were 73 positive cases and 15 negative cases, and the differences had statistical significance （P〉0.05）, and the difference in the test rate of coronary stenosis degree between the two examination methods had no statistical signiflcance （P〉0.05）, CAG showed that there were 108 blood vessels with stenosis, and the test rate of 64 SCTCA for left main and angiostenosis; hemadostenosis in the left anterior descending branch was high, but the test rate for the right circumflex and right angiostenosis was obviously lower than the CAG, and the differences had statistical significance （P〈0.05）. Conclusion The accurate rate and image resolution ratio of 64 SCTCA in diagnosis of coronary heart disease are high, which is of important significance to the diagnosis of coronary heart disease and disease monitoring.
