目的应用64层螺旋CT冠状动脉成像检查方法,探讨冠心病患者冠状动脉斑块成分与狭窄程度之间的相关性,为预测冠心病风险、早期识别易损患者提供诊断依据。方法回顾性分析广东省中医院101例临床拟诊冠心病或冠心病患者的64层螺旋CT冠状动脉成像检查的结果,冠状动脉影像表现由2位心血管CT诊断医师独立判断冠状动脉斑块成分及测量冠状动脉狭窄程度,结果一致时诊断为冠心病。采用SPSS13.0统计分析软件,应用卡方检验和对应分析,探讨冠状动脉斑块成分与狭窄程度之间的相关性。结果在101例患者中,冠状动脉无狭窄30例(30/101,29.7%),轻度狭窄29例(29/101,28.7%),中度狭窄18例(18/101,17.8%),重度狭窄24例(24/101,23.8%)。本组71例冠状动脉不同程度狭窄的患者中,斑块成分中以软斑块(53/71,74.6%)最多见。冠状动脉斑块成分与狭窄程度之间比较具有统计学意义(P〈0.05),提示冠状动脉斑块成分与狭窄程度关系密切。两者之间做对应分析,提示软斑块与重度狭窄、混合性斑块与中度狭窄之间具有密切相关性。结论64层螺旋CT冠状动脉成像能够有效检测冠心病患者冠状动脉斑块的成分及准确判断冠状动脉狭窄程度。利用64层螺旋CT冠状动脉成像对斑块成分评价,可以预测冠心病风险,早期识别易损患者。
Objective To explore the correlation between the coronary plaque composition and the degree of stenosis by 64-slice CT coronary angiography,which can provide the diagnosis evidence for predicting the risk of coronary heart disease and the early identification of vulnerable patients.Methods The data of coronary angiography of 101 patients with suspected or documented coronary artery disease on 64-slice spiral CT in Guangdong Province Hospital of Traditional Chinese Medicine were analyzed retrospectively.The ...
