64层双源螺旋CT冠状动脉成像对冠状动脉狭窄病变的诊断价值

目的探讨多层螺旋CT对冠状动脉狭窄病变的诊断价值。方法选取80例临床诊断为冠心病或可疑冠心病的住院患者,行64层双源螺旋CT冠状动脉成像检查及经皮选择性冠状动脉造影。分别评价冠状动脉狭窄程度,以经皮选择性冠状动脉造影结果作为诊断金标准进行统计学对比分析。结果 64层双源螺旋CT冠状动脉成像诊断冠状动脉狭窄病变的灵敏性73.5%,特异性92.3%,阳性预测值71.7%,阴性预测值93.0%,准确性88.4%。结论 64层双源螺旋CT冠状动脉成像诊断冠状动脉狭窄病变具有无创、经济、灵敏、特异、安全等优点,可以作为无症状心肌缺血冠心病的首选筛查方法。

Clinical values of Coronary Angiography with 64 slice Spiral CT in Patients with Latent

Objective To evaluate the clinical values of 64 slice spiral CT inpatients with coronary heart disease.Methods A total of 80 patients with coronary artery disease underwent 64 slice spiral CT coronary angiography and conventional percutaneous coronary angiography.Then coronary artery stenosis was quantitatively assessed.Results Compared with percutaneous coronary angiography,sensitivity,specificity,positive predictive value,negative predictive value and degree of accuracy of 64 slice spiral CT in diagnosing moderate and severe coronary stenosis were 73.5%,92.3%,71.7%,93.0% and 88.4% respectively.Conclusion As a less invasive,simple,economical,safe and reliable method,64 spiral CT coronary angiography has favourable clinical values in diagnosing latent coronary heart disease and provides information about coronary morphology for advanced interventional therapy.
