摘要
目的对照分析冠状动脉CT血管造影(CTA)与冠状动脉造影(CAG)在冠状动脉狭窄和斑块性质上的诊断价值。方法回顾性分析我院2020年4月至2021年4月收治的136例经CTA和CAG检查的冠状动脉粥样硬化性心脏病(CAD)患者的病例资料,比较分析两种检查方式诊断冠状动脉狭窄和斑块性质的效果。结果CAD患者冠状动脉狭窄程度CAG检查与CTA检查的病变个数差异不显著(P>0.05);CAD患者冠状动脉斑块性质CAG检查与CTA检查的病变个数差异不显著(P>0.05);CTA检查轻度狭窄的敏感度为88.98%,特异度为98.97%,检查中度狭窄的敏感度为96.74%,特异度为99.13%,检查重度狭窄的敏感度为92.96%,特异度为100.00%,检查完全闭塞的敏感度为96.77%,特异度为98.62%;CTA检查软斑块的敏感度为92.98%,特异度为98.55%,检查纤维斑块的敏感度为94.20%,特异度为98.91%,检查硬化斑块的敏感度为94.20%,特异度为100.00%。结论CTA技术检查CAD的冠状动脉狭窄程度及斑块性质的特异度和敏感度与CAG检查效果相当。
Objective To comparatively analyze the diagnostic value of coronary CT angiography(CTA)and coronary angiography(CAG)for coronary stenosis and plaque property.Methods The pathological data of 136 patients with coronary artery disease(CAD)examined by CTA and CAG in the hospital were retrospectively analyzed between April 2020 and April 2021 Value of the two examination methods in the diagnosis of coronary stenosis and plaque property was compared.Results There was no significant difference in the degree of coronary stenosis detected by CAG and CTA(P>0.05).The plaque properties detected by CAG and CTA showed no statistically significant difference(P>0.05).The diagnostic sensitivity and specificity of CTA for mild stenosis were 88.98%and 98.97%,for moderate stenosis were 96.74%and 99.13%,for severe stenosis were 92.96%and 100.00%,and for complete occlusion were 96.77%and 98.62%.The diagnostic sensitivity and specificity of CTA for soft plaque were 92.98%and 98.55%,for fibrous plaque were 94.20%and 98.91%,for atherosclerotic plaque were 94.20%and 100.00%.Conclusion The specificity and sensitivity of CTA in detecting coronary stenosis and plaque properties in patients with CAD are equivalent to those of CAG.
