摘　　要：本研究探讨256层螺旋CT血管造影(CTA)在冠状动脉疾病诊断和心肌桥检测中的意义。选取疑似冠心病患者172例,先后行CTA、冠状动脉造影(CAG)检查。CTA诊断冠心病结果与CAG结果Kappa值为0.801(P<0.05),一致性极佳;CTA判断冠脉血管狭窄程度与CAG结果Kappa值为0.817(P<0.05),一致性极佳;CTA诊断心肌桥结果与CAG结果Kappa值为0.758(P<0.05),一致性极佳;心肌桥伴冠心病患者心肌桥厚度明显高于不伴冠心病患者(P<0.05);心肌桥厚度预测心肌桥患者伴冠心病的ROC曲线下面积为0.900(P<0.05)。在冠状动脉病变及心肌桥诊断中应用256层CTA有较好的价值,值得临床使用。This study explored the significance of 256 slice spiral CT angiography(CTA)in the diagnosis of coronary artery disease and the detection of myocardial bridge.172 patients with suspected coronary heart disease were selected,the CTA and coronary angiography(CAG)were performed.The Kappa value of CTA and CAG in the diagnosis of coronary heart disease was 0.801,P<0.05,showed excellent consistency.The Kappa value of CTA and CAG in determining the degree of coronary artery stenosis was 0.817,P<0.05,which showed excellent consistency.The Kappa value of CTA and CAG in the diagnosis of myocardial bridge was 0.758,P<0.05,showed excellent consistency.The thickness of myocardial bridge in patients with myocardial bridge and coronary heart disease was significantly higher than that in patients without coronary heart disease(P<0.05).The area under the ROC curve for predicting myocardial bridge thickness in patients with myocardial bridge and coronary heart disease was 0.900,P<0.05.The 256-layer CTA has a good value in the diagnosis of coronary artery disease and myocardial bridge,and is worthy of clinical use.
