摘要

目的：运用真实世界数据探究CT-FFR技术对冠心病患者临床应用价值。方法：采用回顾性研究方法，对2022年至2023年期间就诊并接受CCTA及CAG检查的冠心病患者为观察对象，将CCTA原始数据通过CT-FFR软件计算CT-FFR值，以CAG结果为金标准，评价CCTA及CT-FFR对心肌缺血的诊断效能及诊疗决策预判效能。结果：CT-FFR诊断准确性为91.28%，敏感度为87.02%，特异度为93.58%，阳性预测值为87.97%，阴性预测值为93.01%，AUC值0.903，CT-FFR软件诊断功能性心肌缺血优于冠状动脉C TA（P＜0.05），CAG的检查率基于患者水平降低26.71%，基于血管水平可降低25.92%。结论：CT-FFR技术对心肌缺血诊断效能优于CCTA，可避免不必要的CAG检查，节约医疗成本、减轻经济负担。
