心肌梗死患者需要接受各类影像学检查，对心脏损伤的程度进行评估，以便筛查发生心血管事件的高危人群并判断患者预后，从而更加高效地开展临床诊疗工作。心脏损伤的评估主要包括 2个方面，一是对心肌梗死后心室收缩功能和心脏解剖重构的整体评估，二是针对梗死区域的面积、心肌活力以及微循环障碍的评估。目前，临床上常用的影像学检查方法包括心脏超声、心脏磁共振、 CT、核医学检查方法等。该文结合最新研究证据，综述了各类影像学方法在评估心肌梗死后心脏损伤方面的最新应用，为医务工作者临床实践提供参考。

Imaging techniques play a vital role in evaluating myocardial damage in patients with myocardial infarction. Accurate evaluations of post-infarction function and scar can help identify high-risk patients and provide prognosis information, which contributes much to clinical practice. The assessment of myocardial damage mainly includes overall evaluations of ventricular function and remodeling and targeted characterization of myocardial infarction including infarct size, myocardial viability and microvascular obstruction. Echocardiography, cardiac magnetic resonance, CT and nuclear examinations are most common imaging techniques currently. This review is to evidence on applications of these modalities in evaluation of post-infarction myocardial damage and offer some helps to health workers.
