摘　　要：目的:分析256层螺旋CT冠脉成像(CTA)在诊断冠状动脉病变及心肌桥中的应用价值。方法:选取2019年12月-2021年6月于厦门大学附属第一医院接受治疗的疑似冠心病(CHD)患者90例为观察对象,先后行CTA检查及冠状动脉造影检查(CAG),以CAG诊断结果为金标准,分析CTA诊断CHD、冠状动脉血管的狭窄程度及心肌桥的诊断价值。结果:CAG确诊冠心病患者65例,非冠心病患者25例。CTA诊断冠心病的特异度为92.00%(23/25)、灵敏度为92.31%(60/65)、准确度为92.22%(83/90)、阴性预测值为82.14%(23/28)、阳性预测值为96.77%(60/62),CTA诊断具有高度一致性(Kappa=0.813);CTA与CAG对冠状动脉血管的狭窄程度检查诊断结果比较,差异无统计学意义(P>0.05);CTA诊断心肌桥的特异度为86.67%(39/45)、灵敏度为50.00%(10/20)、准确度为75.38%(49/65)、阴性预测值为79.59%(39/49)、阳性预测值为62.50%(10/16),CAG与CTA诊断一致性一般(Kappa=0.388)。结论:256层螺旋CT冠脉成像诊断冠状动脉病变的效果显著,对心肌桥的诊断效果一般。Objective:To analyze the application value of 256-layer spiral CT coronary imaging(CTA)in the diagnosis of coronary artery lesions and myocardial bridges.Methods:Ninety patients with suspected coronary heart disease(CHD)treated in the First Hospital of Xiamen University from December 2019 to June 2021 were selected as observation subjects.CTA examination and coronary angiography(CAG)were performed successively,and the diagnostic value of CTA in diagnosing CHD,the degree of stenosis of coronary vessels and myocardial bridges was analyzed using CAG diagnostic results as the gold standard.Results:CAG confirmed the diagnosis of coronary artery disease in 65 patients and non-coronary artery disease in 25 patients.92.00%(23/25)specificity,92.31%(60/65)sensitivity,92.22%(83/90)accuracy,82.14%(23/28)negative predictive value and 96.77%(60/62)positive predictive value were found for CTA diagnosis of coronary artery disease,and CTA diagnosis showed a high agreement(Kappa=0.813).There was no statistically significant difference between CTA and CAG for the diagnosis of stenosis examination of coronary vessels(P>0.05).86.67%(39/45)specificity,50.00%(10/20)sensitivity,75.38%(49/65)accuracy,79.59%(39/49)negative predictive value and 62.50%(10/16)positive predictive value were found for CTA diagnosis of myocardial bridges.The diagnostic agreement between CAG and CTA was general(Kappa=0.388).Conclusion:256-layer spiral CT coronary imaging is significantly effective in clinical diagnosis of coronary artery lesions,and is generally effective in clinical diagnosis of myocardial bridges.
