Clinical Evaluation Value of CCTA Plaque Quantitative Analysis in Characteristics of Coronary Artery Plaques in Patients with Coronary Heart Disease
Objective To explore the clinical evaluation value of coronary CT angiography(CCTA)plaque quantitative analysis in characteristics of coronary artery plaques in patients with coronary heart disease(CHD).Methods A total of 90 patients with CHD in the hospital were enrolled between June 2019 and June 2022.All underwent CCTA and coronary angiography(CAG).Taking CAG as the golden standard,evaluation results of coronary plaque characteristics(plaque sites,plaque length,volume of calcified plaque,volume of non-calcified plaque,plaque load),coronary remodeling index and stenosis degree by the two methods were compared.The occurrence of major adverse cardiac events(MACE)within 1 year was followed up.The evaluation value of CCTA plaque quantitative analysis indexes for prognosis was analyzed by ROC curves.Results There was no significant difference in plaques or coronary characteristics between CCTA and CAG(P>0.05).After 1 year of follow-up,there were 15 cases(16.67%)with MACE.The characteristics of coronary artery plaques(volume of non-calcified plaque,plaque load),coronary remodeling index and stenosis degree in MACE group were higher than those in non-MACE group(P<0.05).The results of ROC curves analysis showed that remodeling index(AUC=0.731),stenosis degree(AUC=0.676),volume of non-calcified plaque(AUC=0.635)and plaque load(AUC=0.699)were of predictive value for prognosis of CHD patients(P<0.05).Conclusion CCTA plaque quantitative analysis can effectively evaluate the characteristics of coronary artery plaques and predict prognosis of CHD patients.
