摘要: 冠状动脉血流储备（CFR）功能与冠脉微循环有密切的关系。冠脉微循环网是心肌冠状动脉血流调节的关键血管段。最近的研究已证明，高血压的冠脉血流储备减少，冠心病的"无复流现象"以及X综合症都与冠脉微循环病变有关。本文介绍了冠脉微循环病变主要的临床表现、发病机理、诊断手段与防治方法。

Abstract: There is a significant relationship between coronary flow reserve (CFR) and coronary microvascular lesion (CML), which is a key to adjusting the supply of blood in the myocardial muscles. It has been known that the pathological basis for decrease of CFR in hypertension, no－reflow phenomenon in corrronary heart disease and X syndrome is CML. The clinical characteristics, mechanism, methods of diagnosis and treatment will be introduced in this article.
