摘　　要：目的 MSCT对冠状动脉粥样硬化性心脏病患者的狭窄血管内斑块成分的研究。方法选取我院门诊或住院患者因冠状动脉粥样硬化症而就诊的60个病例,按照其临床症状表现分为两组：急性冠脉综合征（ACS）组和稳定型心绞痛（SAP）组。行冠脉CTA检查,获取相关数据,依据测量值〈50Hu、50~130Hu、〉130Hu分为三组,软斑块、混合斑块和钙化斑块,应用AW工作站后处理技术行定量分析,得出的数据使用统计学方法对粥样斑块行定性评估。结果 60例当中,测得软斑块25个、混合斑块31个、钙化斑块36个。不同性质类型斑块与冠心病ACS、SAP组危险因素有着明显相关性（P〈0.05）。结论通过MSCT评价斑块成分,并分析软斑块发生的相关性因素,尽可能为临床提供更多信息,能预测冠心病的危险性,从而有效降低病死率。Objective To discuss the usage of 64- layered spiral CT in analyzing the component of atherosclerosis plaques. Methods 60 patients with main disease of coronary heart disease were enrolled in our study. And they were divided into the acute coronary syndrome（ ACS） group and stable angina pectoris（ SAP）group. Then the data was obtained,and accessed with the post processing software. And the atherosclerosis plaque were divided in line with the CT value,we assumed that the soft plaque with a CT value 50 Hu,the mixed plaque with a CT value from 50 HU to 130 Hu,the calcified plaque with a CT value of 130 Hu. Results There were 25 soft plaques,31 mixed plaques and 36 calcified plaques among the 60 patients. And different properties of plaques did have a significant correlation with the risks of coronary heart disease（ P〈0. 05）. Conclusions With the help of 64- layered spiral CT analyzing the composition of atherosclerosis plaques and the correlation with the risks of coronary heart disease,we can provide more clinical information and predict the risk of coronary heart disease to decrease the incidence of acute coronary syndrome（ ACS）.
