摘要
目的：探讨螺旋CT冠状动脉造影（SCTCA）与冠状动脉造影（CAG）诊断冠心病患者冠状动脉心肌桥的价值。方法回顾性分析877例冠心病患者SCTCA与CAG影像学资料，比较两种影像学检查方式诊断冠状动脉心肌桥的一致性，心肌桥长度及壁冠状动脉狭窄程度的测量结果。结果两种影像学检查方式诊断冠心病患者浅表型心肌桥和深在型心肌桥一致性良好（Kappa =0.872）。CAG 测量浅表型和深在型心肌桥的长度均明显短于 SCTCA 测量结果[（5.46±2.21）mm比（7.12±3.04）mm和（9.75±3.28）mm比（11.38±4.44）mm]，差异有统计学意义（P〈0.05）。CAG测量浅表型和深在型壁冠状动脉狭窄程度明显高于SCTCA[（38.08±6.37）%比（31.69±5.11）%和（60.40±11.86）%比（52.38±9.27）%]，差异有统计学意义（P〈0.05）。结论SCTCA与CAG用于冠心病患者冠状动脉心肌桥诊断临床价值接近，且SCTCA诊断心肌桥长度准确性更佳，而CAG测量壁冠状动脉狭窄程度更佳。
Objective To investigate the clinical value of spiral CT coronary angiography （SCTCA） and coronary angiography （CAG） in the diagnosis of coronary myocardial bridge in patients with coronary heart disease. Methods The imaging data of SCTCA and CAG of 877 patients with coronary heart disease were retrospectively analyzed. The diagnostic consistency of coronary myocardial bridge and the measurement result of myocardial bridge length and mural coronary artery stenosis degree between SCTCA and CAG were compared. Results Two imaging methods in the diagnosis of superficial type and deep type myocardial bridge in patients with coronary heart disease had good consistency （Kappa =0.872）. The CAG measurement results of superficial type and deep type myocardial bridge length were significantly lower than the SCTCA measurement results： （5.46 ± 2.21） mm vs. （7.12 ± 3.04） mm and （9.75 ± 3.28） mm vs. （11.38 ± 4.44） mm, and there were statistical differences （P〈0.05）. The CAG measurement results of superficial type and deep type mural coronary artery stenosis degree were significantly higher than SCTCA measurement results： （38.08 ± 6.37）% vs. （31.69 ± 5.11）% and （60.40 ± 11.86）% vs. （52.38 ± 9.27）%, and there were statistical differences （P〈0.05）. Conclusions SCTCA and CAG in the diagnosis of coronary myocardial bridge in patients with coronary heart disease have good consistency. The SCTCA in diagnosis accuracy of myocardial bridge length is better than CAG, but the CAG in the diagnosis of mural coronary artery stenosis degree is better.
