摘要(Abstract)：

定量血流分数（QFR）是新兴的无创冠状动脉功能学评估技术，与金标准血流储备分数（FFR）相比，QFR具有无创、无药物诱发副作用、无昂贵导丝、可重复性高、流程便捷和耗时少等优点，在冠心病的研究中不断凸显其诊断和预后价值。左主干病变是冠状动脉血管病变的高危分类人群，未经优化的左主干病变血运重建治疗策略严重影响患者预后，加重患者经济负担，影响冠心病诊疗技术的发展。如何提升左主干病变血运重建治疗效果是心血管病医师的一大挑战。冠状动脉功能学评估相关技术不断得到发展和应用，QFR是其中的典型代表，利用QFR对左主干病变进行细致的功能学评估，并指导和优化治疗手段显得非常重要。本文将对QFR的基本原理和QFR在左主干病变中的应用进行综述。
