CTCA定量参数对冠心病患者短期病死预测价值
Predictive Value of Quantitative Parameters of CTCA for Short-term Mor-tality in Patients with Coronary Heart Disease
摘要
Abstract
Objective To investigate the value of quantitative parameters of CT coronary angiography(CTCA)in predicting short-term mortality in patients with coronary heart disease(CHD).Methods In total,200 patients with CHD ad-mitted from March 2021 to March 2023 were selected,and CTCA quantitative parameters(arterial resistance index,total plaque load and minimum CT density of plaques)of CHD patients with different degrees of coronary artery disease(CAD)were compared,and the correlation between CTCA quantitative parameters and the degree of CAD was analyzed.The 1-year postoperative mortality of patients with CHD was analyzed,the correlation between CTCA quantitative parameters and risk of short-term mortality in patients with CHD was explored,and the predictive value of CTCA quantitative parameters for short-term mortality in patients with CHD was evaluated.Results The arterial resistance index and total plaque load of CHD patients with different degrees of CAD increased gradually,and the minimum plaque density decreased gradually(P＜0.05).In CHD patients,the arterial resistance index and total plaque load were positively correlated with disease type,number of lesions and degree of stenosis,while the minimum CT density of plaques was negatively correlated with disease type,number of lesions and degree of stenosis(P＜0.05).Among200 CHDpatients,39(19.50%)died at one year after surgery.Arterial resistance in-dex,total plaque load and minimum CT density of plaques were associated with the risk of short-term mortality in patients with CHD(P＜0.01).The area under the receiver operating characteristic curve of combined detection of arterial resistance index,total plaque load and minimum CT density of plaques was significantly higher than that of individual indicator in prediction(P＜0.05).Conclusion CTCA quantitative parameters are closely related to the degree of CAD in patients with CHD,and the val-ue of CTCA parameters in combination is higher in predicting the risk of short-term mortality in patients with CHD.关键词
