目的：研究多层螺旋CT冠状动脉成像在无症状性心肌缺血（silent myocardial ischemia ，SMI）中的诊断价值。方法选择S M I患者43例，行64排128层螺旋C T冠状动脉成像检查。结果冠状动脉有异常的病例共32例，其中23例发现有不同程度冠状动脉狭窄，12例冠状动脉有钙化斑块，软斑块者11例，心肌桥8例，冠状动脉狭窄合并心肌桥1例，冠状动脉开口异常合并冠状动脉狭窄2例。结论 SMI冠状动脉异常改变发生率较高，CT 冠状动脉成像可检出SM I冠状动脉异常改变，具有重要的临床价值。

Objective To investigate the value of the multi‐slice CT coronary angiography in silent myocardial ischemia (SMI) .Methods 43 patients diagnosed as SMI were included and underwent 64‐row 128‐slice spiral CT coronary angiog‐raphy examination .Results There were abnormalities on CT coronary angiography examination in 32 patients ,including varying degrees of coronary artery stenosis in 23 cases ,coronary artery calcification in 12 cases ,soft plaques in 11 cases , pure myocardial bridge lesions in 8 cases ,myocardial bridge lesion and coronary artery stenosis in 1 case ,and coronary ar‐tery origin anomaly and coronary artery stenosis in 2 cases .Conclusion The incidence rate of coronary artery abnormali‐ties is relatively high in patients with SMI .CT coronary angiography can detect the coronary abnormallities ,which may be important in clinical settings .
