64位螺旋CT在冠状动脉供血不足临床诊断价值

The Clinical Diagnostic Value of 64 Spiral CT for Coronary Insufficiency

目的:探讨分析应用64位螺旋CT冠状动脉成像(64SCTCA)在冠状动脉供血不足中的临床诊断价值。方法:对在2009年8月-2011年8月间我院治疗的65例疑似冠心病患者进行64位螺旋CT冠状动脉成像并将此结果与作为诊断冠心病的金标准冠状动脉造影(CAG)进行比较分析。结果:由于冠状动脉供血不足主要由患者冠状动脉狭窄引起,因此对可评估的262支冠状动脉,64SCTCA显示的冠状动脉狭窄为181支,其中有176支得到CAG证实。64SCTCA诊断狭窄的敏感性可以达到97.2%,特异性可以达到91.2%,阳性预测值可以达到94.9%,阴性预测值可以达到95.1%。结论:64SCTCA具有很高的敏感性和特异性以及阴阳性预测值,在应用64SCTCA诊断患者冠状动脉狭窄程度等病变时具有较高临床价值。

Objective： To investigate the diagnostic value of 64 spiral CT coronary imaging （64SCTCA）for coronary insufficiency. Methods： Patients with suspected coronary artery disease in 65 cases treated in our hospital between August 2009 and August 2011 the results of 64 spiral CT coronary angiography and coronary angiography （CAG） as the gold standard of diagnosis of coronary heart disease compare analysis.Results： Due to coronary insufficiency in patients caused by coronary artery stenosis , 262 on the assessment of coronary artery , coronary artery stenosis 64SCTCA display 181 , including 176 confirmed by the CAG . Diagnosis 64SCTCA narrow sensitivity 97.2% , specificity can be achieved 9 1.2% and can reach 9 4.9% , positive predictive value , negative predictive value of 95.1%.Conclusion： 64SCTCA has high sensitivity and specificity and yin and yang predictive value , patients with coronary artery stenosis and other lesions application 64SCTCA diagnosis with high clinical value.
