摘要:: 目的比较16层螺旋CT冠状动脉成像对冠状动脉造影确诊的两个类型冠心病患者冠状动脉斑块类型分布，并探讨其临床意义。方法将60例住院冠心病患者（均经冠状动脉造影证实为冠心病），据临床诊断分为稳定型心绞痛组（SAP）24 例、急性冠脉综合征组（ACS）36 例，行16层螺旋CT冠状动脉成像，根据螺旋CT值分为软斑块、混合斑块、硬斑块，分析各种不同性质的斑块在两个类型冠心病组的分布。结果两个类型冠心病组斑块类型的分布存在显著性差异(P<0.05)，急性冠脉综合征组以软斑块为主(占50%)，混合斑块次之(31%)；而稳定型心绞痛组则以硬斑块为主(占62%)。结论 16层螺旋CT冠脉成像可较准确地显示斑块性质，结合冠心病临床分型对冠状动脉斑块稳定性的判别有一定临床价值。

Abstract:: AIM To evaluate coronary plaque using 16slice spiral computed tomography (CT) angiography in patients with coronary heart disease（CHD）confirmed by coronary angiography. METHODS Sixty patients with CHD were confirmed by coronary angiography and divided into stable angina pectoris (SAP, n=24) and acute coronary syndrome (ACS, n=36) groups based on the clinic diagnosis. All the patients underwent 16slice spiral CT coronary angiography to quantify the coronary plaque and then were divided into soft plaque (n=24), mixed plaque (n=14) and hard plaque (n=22) groups based on the CT scale. RESULTS Soft plaque and mixed plaque in the ACS group were more than those in the SAP group (soft plaque: 18 vs 6 cases, ACS vs SAP, P<0.05; mixed plaque: 11 vs 3 cases, ACS vs SAP, P<0.05) and hard plaque in the SAP group was more than that in the ACS group (15 vs 7 cases, SAP vs ACS, P<0.05). CONCLUSION 16-slice spiral CT can be used to assess coronary plaque with high accuracy and together with clinical type of CHD it can also be used to evaluate the stability of coronary plaques.
