Pressure-bound (pb) coronary flow reserve (CFR) is a novel estimation of CFR, calculated from easily obtained baseline and hyperemic pressure assessment Validation of pb-CFR in previously reported lesions showed accuracy of 84% to CFR with sensitivity of 96% and specificity of 60% FFR >0.75 and low pb-CFR in DEFER was associated with increased angina and complications compared to high pb-CFR and this risk was not modified by elective revascularization.
压力限制（pb）冠状动脉血流储备（CFR）是一种新的CFR评估方法，通过易于获得的基线和充血压力评估计算得出。先前报道的病变中pb-CFR的验证显示，其对CFR的准确性为84%，敏感性为96%，特异性为60%。与高pb-CFR相比，DEFER研究中FFR>0.75且pb-CFR低的患者心绞痛和并发症增加，而这种风险并未因选择性血运重建而改变。
