摘要
目的评估基层医院多层螺旋CT(MSCT)行冠状动脉检查的准确性。方法收集在基层医院已行MSCT检查,提示冠状动脉狭窄患者90例,再经北京阜外心血管病医院行冠状动脉造影确诊,采用Kappa检验比较2种检查方法结果的一致性。结果 MSCT诊断冠心病的准确率为88.9%。诊断冠状动脉狭窄程度的准确率39.0%,诊断左前降支、左回旋支和右冠状动脉的准确率分别为45.5%、37.5%和33.3%。在诊断心肌肌桥两者无一相符,诊断钙化准确率较高为80.0%。MSCT检查冠状动脉各节段的狭窄与冠状动脉造影一致性差。左主干、左前降支、左回旋支和右冠状动脉的Kappa值均<0.75。结论基层医院MSCT诊断冠心病的准确率较高,但在诊断血管狭窄程度上准确率较低。
Objective To evaluate the accuracy of multislice computer tomography（MSCT） for diagnosing the stenosis in coronary artery by taking coronary angiography（CAG） as the reference in primary hospital. Methods The coronary artery imaging data of 90 patients undergoing MSCT in primary hospital and CAG during May to July of 2009 in Fuwai Hospital were collected. Evaluation concerning the accuracy of MSCT in primary hospital was done. Results MSCT examination in the diagnosis of coronary heart disease in primary hospital had high accuracy,but the accuracy in detecting stenosis of special coronary artery segment and myocardial bridging was low. The positive rate of coronary artery calcified plaque was high by MSCT examination in primary hospital. Conclusion The accuracy of MSCT examination in primary hospital needs to be improved.
