Assessment value of the quantitative parameters of CCTA combined with the QRS wave complex of ECG for grading of cardiac function in patients with CHD
摘要
Abstract
Objective:To analyze the assessment value of the quantitative parameters of coronary computed tomography angiography(CCTA)combined with QRS wave complex of electrocardiogram(ECG)for grading of cardiac function in patients with coronary heart disease(CHD).Methods:Eighty CHD patients admitted to Beijing Rehabilitation Hospital,Capital Medical University between January 2023 and December 2024 were selected.The grading of cardiac function of CHD patients were assessed according to the standard of New York Heart Association(NYHA).All patients underwent CCTA and ECG upon admission.CCTA quantitative parameters and QRS wave complex duration were recorded and compared among patients with different grades of cardiac function.The correlation between CCTA quantitative parameters[non-calcified plaque volume(NCPV),calcified plaque volume(CPV),total plaque volume(TPV),vessel volume,reconstruction index],QRS wave complex duration,and grading of cardiac function of CHD patient was analyzed.The area under curve(AUC)of receiver operating characteristic(ROC)curve was used to analyze the value of each parameter and QRS wave complex duration in assessing CHD patients whose cardiac function grade was≥III grade.Results:In the 80 CHD patients,NYHA grades were distributed as follows:11 cases were grade I,and 23 cases were grade II,and 27 cases were grade III,and 19 cases were grade IV.The NCPV,CPV,TPV,reconstruction index,and QRS wave complex duration of patients at grade III and grade IV were higher than those of patients at grade I-grade II,and the differences were significant(F=17.401,37.077,12.297,7.087,11.148,P<0.05).Furthermore,patients at grade IV showed higher values in all parameters than those of patients at grade III.The NCPV,CPV,TPV,reconstruction index(t=3.486,4.315,3.444,2.068,2.600,P<0.05),and QRS wave complex duration of CCTA parameters showed positive correlations with cardiac function grading in CHD patient(r=0.464,0.548,0.346,0.287,0.373,P<0.05).ROC curve analysis revealed that the AUC values of alone NCPV,CPV,TPV,reconstruction index,QRS wave complex duration of CCTA parameters,and the combination of these indicators were respectively 0.793,0.843,0.723,0.748,and 0.737 in assessing CHD patients whose cardiac function grade was≥III,which indicated that these indicators had a certain assessment value,and the combined detection can improve the AUC value and sensitivity.Conclusion:The combination of CCTA parameters(NCPV,CPV,TPV,reconstruction index)and QRS wave complex duration can improve the assessment value for CHD patients whose grade of cardiac function is≥grade III.关键词
