摘　　要：近年来,随着人们对心肌桥(MB)的认知不断加深,研究发现,MB可能与劳力性心绞痛、急性冠状动脉综合征甚至心源性猝死等不良事件有关,但是单从形态学不足以评估MB所致心肌缺血的严重程度。随着血流储备分数(FFR)及定量血流分数(QFR)等功能学评估技术的问世与普及,对冠状动脉狭窄所致的心肌缺血的评估愈发精准化。既往研究尝试使用功能学评估技术对MB与心肌缺血程度之间的关系进行探索。本文就不同功能学技术评估MB所致心肌缺血的研究进展进行综述。In recent years,with the increasing understanding of myocardial bridging(MB),studies have found that MB may be associated with exertional angina pectoris,acute coronary syndromes,even sudden cardiac death,but morphology alone is not enough to evaluate the severity of MB-induced myocardial ischemia.With the advent and popularity of functional assessment techniques such as fractional flow reserve(FFR)and quantitative flow ratio(QFR),the assessment of myocardial ischemia caused by coronary stenosis has become more accurate.Several previous studies attempted to explore the relationship between MB and the degree of myocardial ischemia using functional assessment techniques.This article reviews the research progress of different functional techniques in evaluating MB-induced myocardial ischemia.
