摘要
目的以常规冠脉造影作为冠心病诊断的参考标准,回顾性对比冠脉320CT成像对胸痛患者冠心病诊断的准确性。方法根据冠脉320CT及常规冠脉造影结果,分析320CT对不同狭窄程度的冠脉显示的敏感性、特异性、阳性预测值、阴性预测值、准确率及不同冠脉分支病变的相关性。结果冠脉320CT诊断冠心病的总体敏感性、特异性、阳性预测值、阴性预测值及准确率分别为91%、83%、87%、88%和88%;对不同冠脉分支病变诊断的一致性较高(r>0.70)。结论冠脉320CT诊断冠心病的准确率较高,可胜任胸痛的鉴别诊断和冠心病的筛查,为冠心病的进一步治疗提供准确资料,使冠心病的治疗更具有针对性。
Objective CAG as the reference standard for diagnosis of CHD, retrospectively compared 320CT imaging to the patients with chest pain of diagnostic accuracy of CHD. Methods According to 320CT and CAG results, analysis of 320CT coronary stenosis on different shows sensitivity, specificity, positive predictive value, negative predictive value, accuracy, and the different branches of coronary artery disease associated. Results 320CT diagnosis of CHD overall sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 91%, 83%, 87%, 88% and 88% respectively, for different branches of coronary artery narrow higher consistency. Conclusion 320CT higher accuracy of diagnosis of CHD, chest pain may be capable of differential diagnosis and screening of CHD, further treatment of CHD to provide accurate information to enable more targeted treatment of CHD.
