64层螺旋CT对冠状动脉粥样硬化斑块的诊断价值

目的：探讨64层螺旋CT对冠状动脉粥样硬化斑块的诊断价值。方法：将63例临床诊断为冠心病患者根据临床表现分为二组：急性冠脉综合征（ACS）组和稳定型心绞痛（SAP）组。均行64层螺旋CT冠状动脉成像检查,对检出的斑块进行定性分析,并对各种性质斑块所引起的管腔狭窄程度进行分析。结果：63例中ACS组44例,检出软斑块30个,中等密度斑块18个,钙化斑块11个;稳定型心绞痛组19例中检出软斑块6个,中等密度斑块6个,钙化斑块18个,非钙化斑块（软斑块和中等密度斑块）与冠心病危险性有明显的相关性（P〈0.05）;非钙化斑块导致管腔狭窄程度：轻度狭窄14处,中度狭窄14处,重度狭窄32处;钙化斑块导致管腔狭窄程度：轻度狭窄14处,中度狭窄7处,重度狭窄8处,不同性质斑块与其导致管腔狭窄程度无明显的相关性（P〉0.05）。结论：64层螺旋CT冠状动脉成像能够对冠状动脉粥样斑块进行定性分析,可作为评价冠心病危险性度的一种检查技术。

Value of 64-slice Spiral Computed Tomography in the Diagnosis of Coronary Atherosclerotic Plaque

Objective:To evaluate 64-slice spiral computed tomography in diagnosis of coronary atherosclerotic plaque.Methods:63 patients with coronary heart disease(CHD) were divided into two groups:acute coronary syndrome(ACS) and stable angina pectoris(SAP).All patients underwent 64-slice spiral computed tomography coronary angiography,the coronary plaques detected were analyzed qualitatively and the degree of lumen stenosis was analyzed as well.Results:Of the 63 patients,there were 44 patients with ACS including pl...
