目的：利用 CT 冠状动脉成像,观察并比较无症状心肌缺血(SMI)患者与有症状心肌缺血患者冠状动脉病变的差异。方法本研究共包括 SMI 患者43例,有症状心肌缺血患者45例,分别行64排128层螺旋 CT 冠状动脉成像检查。结果23例 SMI患者发现有冠状动脉狭窄(23/43,53.49%),21例有症状心肌缺血患者发现有冠状动脉狭窄(21/45,46.67%),两者冠状动脉狭窄总的发生率无明显差别(P >0.05),但是两者狭窄程度及病变血管数量有明显差异(P <0.05),有症状心肌缺血冠状动脉斑块及软斑块发生率也明显高于 SMI 患者(P <0.05)。结论SMI 冠状动脉狭窄与有症状心肌缺血冠状动脉狭窄总的发生率无明显差别,但是有症状心肌缺血患者冠状动脉狭窄程度以及斑块发生数量明显高于 SMI 患者。

Objective To compare coronary artery abnormality between patients with silent myocardial ischemia (SMI)and pa-tients with symptomatic myocardial ischemia using coronary artery CT angiography.Methods Forty-three patients with SMI and 45 patients with symptomatic myocardial ischemia were collected and underwent coronary CT angiography using 128-slices spiral CT scanner,respectively.Results Stenosis of coronary artery detected in 23 patients with SMI was (23/43,53.49%),and stenosis in 21 patients with symptomatic myocardial ischemia was (21/45,46.67%).The difference of incidence had no statistical significance, but the degree of stenosis and the number of stenosis vessel had statistical significance(P <0.05).The number of atherosclerotic plaque of coronary artery detected in patients with symptomatic myocardial ischemia was significantly more than that in patients with SMI(P <0.05).Conclusion There are no significant difference in the incidence of coronary stenosis between the patients with SMI and patients with symptomatic myocardial ischemia.However,the degree of stenosis and incidence of atherosclerotic plaque are sig-nificant different.
