摘　　要：近年来急性心肌梗死有呈增高趋势的发病率和病死率及年龄状态分布呈年轻化趋势,也是致人类死亡的主要原因之一。急性心肌梗死的梗死相关动脉的再通成为处理的首要任务,但是再通后患者预后仍有差别。罪犯血管开通后仍有部分患者存在左心室结构与功能改变等一系列问题成为临床预后的主要问题。正确有效评估心肌梗死后左房大小、左室功能、微血管阻塞,对于急性心肌梗死患者的预后评估具有重要意义。心脏磁共振成像技术具有多序列、多层面的成像特点,具有良好的软组织对比度和高空间分辨率,近十年来越来越多地应用于临床,对心肌梗死后心肌坏死区域、心肌重构、心脏功能及微血管灌注极具优势,均为急性心肌梗死后预后指标,现综述心脏磁共振技术评估急性心肌梗死预后的研究进展。The incidence and mortality rates of acute myocardial infarction(AMI)has increasing over recent years,occurring at an increased rate among younger people,and is a leading cause of death worldwide.The recanalization of the obstructed vessel resulting in the AMI is the primary treatment,however the prognosis of patients remains difficult.The progressive left ventricular(LV)dilation and decrease in LV function in part of the patient remain the main clinical and prognostic issues.The accurate quantifications of left atrial size,LV function and microvascular obstruction(MVO)are essential for the prognostic of the patients with AMI.Cardiac magnetic resonance(CMR)has multi-faceted and varied sequenced imaging characteristics,and offers good soft tissue contrast and high spatial resolution,making CMR increasing applied in clinic.CMR has advantages for depicting prognosis such as infarct size,myocardium remolding and MVO after AMI.We reviewed the research progress of CMR prognostic indicator after acute myocardial infarction.
