The comparative analysis of 320CT and exercise stress ECG in diagnosis of coronary artery disease

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 significantly 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 undergoing conventional coronary angiography.
