Non-Q wave myocardial infarction is a distinct and changing clinical entity characterized by lower initial mortality and a higher rate of reinfarction compared to Q wave infarction. Clinical and pathologic data suggest that the syndrome results from transient or incomplete coronary occlusion resulting in an infarct which is smaller than when Q waves are present. High-risk patients can be identified during hospitalization, allowing for aggressive therapy aimed at revascularization. Relatively few clinical trials have examined initial therapy or secondary prevention in this group of patients. These studies are reviewed and management guidelines suggested.
非Q波心肌梗死是一种独特且不断变化的临床实体，与Q波梗死相比，其初始死亡率较低，但再梗死率较高。临床和病理数据表明，该综合征是由短暂或不完全的冠状动脉闭塞导致的，所形成的梗死灶比出现Q波时的梗死灶小。高危患者可在住院期间被识别出来，从而进行旨在血管重建的积极治疗。相对较少的临床试验研究了这类患者的初始治疗或二级预防。本文对这些研究进行了综述并提出了管理指南。
