目的 讨论研究应用64排螺旋CT冠脉成像技术在诊断冠心病方面的临床价值与意义。方法方便选择该院心内科2015年1—10月疑似冠心病患者100例，冠脉主干及主要分支400节段进行重建与分析，进行64排螺旋CT冠状动脉成像及选择性冠状动脉造影。将选择性冠状动脉造影作为判断冠心病的金标准与64排螺旋CT冠脉成像结果进行比较。结果64排螺旋CT冠脉成像检查诊断冠心病灵敏度为95.8%，特异度为95.2%，阳性预测值为94.8%，阴性预测值为96.1%。对不同节段病变诊断灵敏度与特异度较高。结论 64排螺旋CT冠脉成像对患者损伤较小，安全系数较高，对疾病分层治疗及临床医生选择治疗方案均具有重要意义。

［Abstract］Objective To study the clinical significance of 64-slice spiral CT coronary angiography in the diagnosis of coronary heart disease.Methods 100 suspected patients with coronary heart disease from January 2015 to October 2015 in our cardiology department were selected.Reconstruction and analysis of the main coronary artery and the main branches of the coronary artery，64-slice spiral CT coronary angiography and selective coronary angiography were performed.The subjects received the 64-slice spiral CT coronary angiography and selective coronary angiography.Results The sensitivity of 64 slice spiral CT coronary angiography in diagnosing coronary artery disease was 95.8%，the specificity was 95.2%，positive predictive value was 94.8%，negative predictive value was 96.1%.The diagnostic sensitivity and specificity of different segments were higher.Conclusion The 64-slice spiral CT coronary angiography with fewer injury and higher safety，it is of great importance in the gradation treatment and selection of therapies in clinical practices.

冠心病作为心血管疾病中的常见病与多发病近年来发病率较往年显著上升且患者年龄呈年轻化趋势发展。一般来说，患者多以心悸、心慌为主要症状，主要是由于动脉管壁出现粥样斑块造成血管阻塞或狭窄进而导致心肌供血不足所致。目前临床将选择性冠状动脉造影作为诊断冠心病的金标准［1］。本实验为研究64排螺旋CT冠脉成像技术用于诊断冠心病的临床意义与价值，方便选取该院心内科2015年1—10月100例疑似冠心病患者临床资料进行分析，现报道如下。……
