摘要

目的：研究基于冠状动脉 CT 的血流储备分数(FFRCT)指导冠心病患者治疗的价值。方法：收集 2020 年 1 月-2021 年 2
月我院就诊的冠心病或疑似冠心病患者 82 例，按检查方式分为冠状动脉 CT 血管成像（coronary computed tomography angiography，
CCTA）+FFRCT 组 52 例和 CCTA+侵入性冠状动脉导管造影（Invasive coronary angiography, ICA）组 30 例。FFRCT 组中，当
FFRCT>0.8 采取药物保守治疗；当FFRCT≤0.8 时，患者行ICA 检查，FFRCT≤0.8 且ICA<50%时行保守治疗，FFRCT≤0.8且ICA≥50%
时行介入治疗。ICA 组中当 ICA≥70%行介入治疗；ICA<70%行保守治疗，随访两组患者 1 年内心血管不良事件发生及治疗费用等
情况。结果：对两组患者随访 12 个月后，ICA 组 30 例患者中行支架植入 26 例，再发心前区不适 14 例，心绞痛住院 2 例，心衰
1 例；FFRCT 组 52 例患者中再发心前区不适 9 例，心绞痛住院 5 例，心肌梗死 1 例。ICA 组和 FFRCT 组的不良事件发生率、有
创检查率和支架植入率分别为: 56.7%vs.28.8%（P<0.05），100%vs.86.7%(P<0.05)，84.6%vs.53.8%（P<0.05）。结论：FFRCT 指
导介入治疗相较于 ICA，降低不良事件发生率，同时减少了不必要的检查及介入治疗。
