Objective:To explore the application value of coronary CT angiography(CCTA)and DSA in the diagnosis of coronary artery plaques.Methods:A total of 64 patients with coronary heart disease in the hospital were enrolled between January 2020 and May 2023.All the patients underwent CCTA and DSA.The detection rates of coronary artery plaques by CCTA and DSA were calculated.Taking DSA as the golden standard,the diagnostic values of CCTA in plaque property and stenosis degree were analyzed.Results:Among the 64 patients,there were 58 cases(90.63％)with coronary artery plaques in DSA,including 21 cases with mild stenosis,23 cases with moderate stenosis,and 14 cases with severe stenosis.There were 55 cases(85.94％)with coronary artery plaques in CCTA,including 19 cases with mild stenosis,22 cases with moderate steno-sis,14 cases with severe stenosis,12 cases with non-calcification plaques,13 cases with mixed plaques,and 30 cases with calcification plaques.Taking DSA as the golden standard,sensitivity,specificity,accuracy,positive predictive value,negative predictive value and Kappa coefficient of CCTA in the diagnosis of coronary artery plaques were 94.83％,83.33％,93.75％,98.21％,62.50％and 0.680.There was no significant difference in the detection of coronary stenosis between CCTA and DSA(P＞0.05).Calcification plaques in patients with mild stenosis was higher than that with moderate and severe stenosis,while non-calcification and mixed plaques was lower than that with moderate and severe stenosis(P＜0.05).Conclusion:CCTA has high consistency with DSA in the diagnosis of coronary artery plaques and stenosis degree.Moreover,CCTA has a higher di-agnostic value for plaque properties compared to DSA.
