冠脉无复流是指血管造影无血管机械性阻塞的证据,而冠脉循环所支配的节段心肌灌注不足的一种现象。本文对无复流的概念、分类及可能的机制以及对介入患者的预后进行探讨。认为冠脉无复流的发生是包括血管内皮损伤、微血管阻塞、氧自由基等多因素作用所致,并且与介入患者的预后密切相关。
Coronary no-reflow refers to the evidence that angiography has no mechanical vascular occlusion, whereas coronary circulation is a phenomenon characterized by inadequate myocardial perfusion. This article explores the concept, classification and possible mechanisms of no-reflow, and the prognosis of patients involved. Coronary no-reflow is thought to be caused by many factors including vascular endothelial injury, microvascular occlusion and oxygen free radicals, which are closely related to the prognosis of patients.
