256层多排螺旋CT冠状动脉成像在稳定型和不稳定型心绞痛中的诊断价值

摘要

目的：探讨稳定型与不稳定型心绞痛患者的冠状动脉脉粥样硬化斑块特征在256层多排螺旋CT心脏冠状动脉CTA的表现。方法选取96例以心绞痛入院的患者，分为稳定型心绞痛（ SAP）组和不稳定型心绞痛（ UAP）组，对冠状动脉斑块的钙化积分和斑块性质进行对比分析。结果 UAP组在非钙化斑块发生率、混合性斑块发生率明显高于SAP组，钙化斑块发生率明显低于SAP组。结论 CT冠状动脉成像检查能有效鉴别冠状动脉斑块的稳定性，为临床心绞痛的诊治提供依据。%Objective To investigate the performance of CTA by the 256-MSCT on coronary atherosclerotic plaque characteris-tics between the stability and unstable angina pectoris .Methods 96 patients with angina admitted to hospital were selected and divided into stable angina pectoris ( SAP) group and unstable angina pectoris ( UAP) group.We conducted a comparative analysis of the calcification score and the characteristics of plaque in the coronary artery .Results The incidence of non-calcified and mixed plaque in UAP group was significantly higher than that of the SAP group .The incidence of calcified plaque was significantly lower than that of SAP group .Conclusion CT coronary artery imaging can effectively identify the stability of coronary artery plaque , which provides the basis for clinical diagnosis and treatment of angina pectoris .
