Correlation and Joint Predictive Value of Carotid Ultrasound in Evaluating the Degree of Carotid Atherosclerosis and MSCTA in Evaluating the Degree of Coronary Stenosis
Objective To study and analyze the correlation and joint predictive value of carotid ultrasound in evaluating the degree of carotid atherosclerosis and MSCTA in evaluating the degree of coronary stenosis.Methods 300 patients with confirmed or suspected coronary heart disease admitted to the Department of Cardiology of our hospital from January 2017 to December 2019 were selected.All patients underwent multi-slice spiral CT angiography(MSCTA),carotid color Doppler ultrasound and coronary angiography(CAG).Taking CAG examination as the gold standard,the diagnostic indexes such as detection rate,positive rate,sensitivity,specificity and prediction accuracy of the above two diagnostic methods were calculated,and the ultrasound was studied and analyzed.Results The consistency between ultrasound and CAG was Kappa=0.588,and that between MSCTA and CAG was kappa=0.503(P＜0.05).The accuracy,sensitivity,specificity,positive predictive value and negative predictive value of ultrasound in evaluating the degree of carotid atherosclerosis were 80.33％,80.95％,79.28％,86.93％and 70.97％respectively.The accuracy of MSCTA in evaluating the degree of coronary artery stenosis was 81.07％,and the accuracy,sensitivity,specificity,positive predictive value and negative predictive value of mild stenosis were 83.54％,83.72％,83.33％,85.04％and 81.90％respectively.Moderate stenosis was 84.36％,65.28％,92.40％,78.33％and 86.34％respectively.Severe stenosis was 86.83％,78.57％,88.56％,58.93％and 95.19％respectively.There was a positive correlation between carotid ultrasound and MSCTA in evaluating the degree of carotid atherosclerosis(r=0.852,P＜0.05).Conclusion Carotid ultrasound evaluation and MSCTA evaluation are in good agreement with CAG gold standard in diagnosing the degree of coronary sclerosis and stenosis of coronary heart disease,which is helpful to improve the diagnostic value of coronary heart disease,and it has the advantages of non-invasive,simple and convenient,and high repeatability,and is worthy of clinical application.
