Analysis of the Value of Coronary CT Angiography in Determining Lesions in Patients with Coronary Artery Disease
Objective To investigate the application effect of coronary artery computed tomography(CT)angiography in determining lesions in patients with coronary heart disease.Methods Retrospectively selected 97 cases of coronary artery disease patients admitted in our hospital from April 2022 to April 2023 as study samples,grouped according to the plaque progression of the enrollees,and divided the enrollees into coronary artery disease progression group(n=58)and coronary artery disease stabilization group(n=39),and all of the enrollees were subjected to coronary artery CT angiography examination.Coronary CT angiography parameters such as remodeling index(RI),plaque load,percentage of high-risk plaque(HRP),and plaque volume were compared between the two groups to analyze the correlation between the above parameters and the degree of progression of coronary artery disease plaques,and to draw the subjects'workup characteristic(ROC)curves,and to calculate the area under the curve(AUC),the sensitivity,the Jordon's index,and the optimal threshold value.Results The RI and plaque load levels,HRP percentage,and plaque volume were higher in the coronary heart disease progression group than in the coronary heart disease stabilization group(P<0.05).There was a positive correlation between all of the above parameters and the degree of coronary plaque progression(r=0.758,0.620,0.611,0.616,P<0.05),and the AUC values of RI,plaque load,HRP percentage,and plaque volume were 0.958,0.870,0.811,0.873,respectively,with an AUC value of>0.6.Conclusion Coronary CT angiographic Angiography parameters(RI,plaque load,HRP percentage,plaque volume)are positively correlated with the degree of coronary plaque progression,and the above parameters have excellent diagnostic value for the degree of coronary plaque progression.
