最近一系列的研究表明 ,在无心外膜冠状动脉粥样硬化性阻塞病人 ,冠状动脉微栓塞可能是心肌节段性收缩功能异常的原因 ,本文试图提供冠脉微栓塞的证据 ,并分析它的来源和后果。1　组织学证据39年前 ,报告在动物实验中 ,血小板和凝血栓子栓塞冠状微循环 ,随之发生微梗死和致命的 A recent series of studies have shown that coronary micro-embolism may be responsible for abnormal segmental myocardial systolic function in patients with unintended epicardial coronary atherosclerotic occlusion. This article attempts to provide evidence of coronary micro-embolism and to analyze its Sources and consequences. 1 histological evidence 39 years ago, reported in animal experiments, platelet and thromboembolism coronary microcirculation, followed by micro-infarction and fatal
