摘　　要：目的:分析冠心病(CHD)患者电子计算机断层扫描血管造影(CTA)影像学特征及其对主要不良心脏事件(MACE)的预测价值。方法:CHD患者280例,随访1年发生MACE51例。分析CHD患者发生MACE的危险因素,绘制受试者工作特征(ROC)曲线分析其预测价值。结果:合并糖尿病、管腔直径狭窄率增加、斑块长度增加,FFRCT降低为CHD患者发生MACE的危险因素(P<0.05)。联合检测多项指标对CHD患者发生MACE的预测价值最高,曲线下面积(AUC)为0.930。结论:CTA影像学特征及合并糖尿病均与CHD患者发生MACE密切相关,联合检测预测价值较高。Objective:To analyze the imaging features of computed tomography angiography(CTA)in patients with coronary heart disease(CHD)and its value in predicting major adverse cardiac events(MACE).Methods:A total of 280 CHD patients were followed up for 1 year and 51 cases of MACEAE occurred.Risk factors for MACE in CHD patients were analyzed,and receiver operating characteristic(ROC)curve was plotted to analyze its predictive value.Results:Diabetes mellitus,increased lumen diameter stenosis rate,increased plaque length,and decreased FFRCT were risk factors for MACE in CHD patients(P<0.05).Combined detection of multiple indicators had the highest predictive value of MACE in CHD patients,and the area under the curve(AUC)was 0.930.Conclusion:The imaging features of CTA and diabetes mellitus are closely related to the occurrence of MACE in CHD patients,and the combined detection has high predictive value.
