摘要
目的选择常规冠脉造影作为冠心病诊断"金标准",回顾性对比冠脉320CT与运动负荷心电图对冠心病的诊断性能。方法根据冠心病诊断标准,分析80例怀疑冠心病患者的冠脉320CT、运动负荷心电图对冠心病诊断的敏感性和特异性。结果冠脉320CT的敏感性(90.9%)和特异性(83.3%)比运动负荷心电图的敏感性(72.7%)和特异性(30.6%)显著增高(P<0.05);在怀疑冠心病的中低危患者中,冠脉320CT对冠心病诊断的准确率优于运动负荷心电图,差异有统计学意义(P<0.05)。结论在常规行冠脉造影检查的患者中,冠脉320CT诊断冠心病性能优于运动负荷心电图。
Objective To choose the conventional coronary angiography as the ＂gold standard＂ for diagnosing coronary artery disease （CAD）, retrospectively compare the performance of coronary 320CT and exercise stress ECG in diagnosis of CAD. Methods According to diagnostic criteria for CAD, sensitivity and specificity of 320CT and exercise stress ECG in diagnosis of 80 cases CAD were analyzed. Results The sensitivity （90.9%） and specificity （83.3%） of 320CT were signifi- cantly higher than the sensitivity （72.7%） and specificity （30.6%） of exercise stress ECG （P 〈 0.05）; The studies had shown that the diagnosis rate of 320CT of CAD had significantly statistical difference than exercise stress ECG in suspected CAD low-risk patients （P 〈 0.05）. Conclusion 320CT is superior to exercise stress ECG in diagnosis of CAD for patients under- going conventional coronary angiography.
