Diagnostic Value Of Stress Echocardiography And Coronary CTA In Patients With Moderate To Low Risk Chest Pain

Objective: Using the results of Coronary angiography as the criteria for the diagnosis of Coronary Artery Disease,Stress Echocardiography was investigated.Coronary SE and coronary enhanced CT Angiography in the diagnosis of low-risk patients with chest pain,thus providing real and effective reference information for cardiologists to select non-invasive examinations.Methods: 86 patients with moderate and low risk chest pain who underwent SE and CCTA examination were collected to analyze the diagnostic value of SE and CCTA in CAD patients with moderate and low risk chest pain,and the results of CAG examination were recorded after the completion of the two examinations.Results: The sensitivity and specificity of SE in diagnosing CAD were 89.1% and86.3% respectively.The accuracy rate was 88.3%;The sensitivity,specificity and accuracy of CCTA in diagnosing CAD were 92.1%,90.9% and 91.9% respectively.The specificity of CAD diagnosis in series was 95.5%,and the sensitivity and accuracy of CAD diagnosis in parallel were 95.3% and 91.8%,respectively.The detection rate of SE multi-vessel lesions was significantly higher than that of single vessel lesions(97.1%,79.3%,P < 0.05),while the detection rate of CCTA multi-vessel lesions was not significantly different from that of single vessel lesions(91.4%,93.1%,P > 0.05).Conclusion: SE and CCTA,as non-invasive tests,have higher specificity and sensitivity in diagnosing CAD in patients with moderate and low risk chest pain,and the detection rate of SE in CAD coronary multi-vessel lesions is higher than that in single-vessel lesions.The specificity of SE and CCTA in the diagnosis of CAD by tandem study was 95.5%,which could reduce the misdiagnosis rate.The sensitivity and accuracy of CAD diagnosis in parallel study were 95.3% and 91.8%,respectively,which reduced the rate of missed diagnosis.
