摘　　要：目的探讨冠状动脉CT血管成像(CCTA)联合负荷动态心肌CT心肌灌注成像(CT-MPI)在冠心病(CHD)心肌缺血(MI)诊断及治疗指导中的应用价值。方法回顾性分析本院2018年1月至2019年12月期间收治的468例疑似CHD患者的临床病历资料以及影像学资料。结果468例疑似CHD患者经有创性冠状动脉造影(ICA)确诊MI285例,无MI183例;以ICA结果作为“金标准.”,CCTA联合CT-MPI诊断CHD患.者MI的敏.感度9860%高于.上述检查单一检查的8070%、8.316%,准.确度903.8%高于上述检查单一检查的8034%、8120%(P<005)。结论CCTA联合CT-MPI能提高CHD患者MI的诊断价值,可为临床治疗提供科学参考依据。Objective To explore the application value of coronary CT angiography(CCTA) combined with dynamic CT myocardial perfusion imaging(CT-MPI) in the diagnosis and treatment guidance of myocardial ischemiawith coronary heart disease(CHD). Methods The clinical medical records and imaging data of 468 patients with suspected CHD who were admitted to the hospital from January 2018 to December 2019 were retrospectively analyzed. Results Among the 468 patients with suspected CHD, there were 285 cases with myocardial ischemia and 183 cases without myocardial ischemia confirmed by invasive coronary angiography(ICA). Taking ICA results as the golden standard, the sensitivity and accuracy of CCTA combined with CT-MPI for diagnosis of CHD myocardial ischemia were higher than those of CCTA and CT-MPI alone(98.60% vs 80.70%, 83.16%),(90.38% vs 80.34%, 81.20%),(P<0.05). Conclusion CCTA combined with CT-MPI can improve the diagnostic value of myocardial ischemia in CHDpatients, which can provide scientific reference for clinical treatment.
