Two-dimensional and Doppler echocardiography have become extremely useful in the management of patients with acute myocardial infarction (AMI). Echocardiography is noninvasive, relatively inexpensive, and has no known biohazards. It offers unequaled information about cardiac anatomy and function. In the acute setting it is useful in the diagnosis of AMI and its complications. It is an excellent tool for monitoring therapy. Echocardiography has been shown to be useful in risk stratification upon presentation to the emergency ward and prior to hospital discharge. Stress echocardiography has broadened and sharpened the diagnostic and prognostic information. Contrast echocardiography has promise for demonstrating coronary artery flow. Research in ultrasonic myocardial tissue characterization shows potential for differentiating ischemic myocardium from infarcted myocardium. Thus, echocardiography is likely to become increasingly important in the future management of patients with AMI.
二维及多普勒超声心动图在急性心肌梗死（AMI）患者的管理中已变得极为有用。超声心动图检查是非侵入性的，相对廉价，且不存在已知的生物危害。它能提供关于心脏解剖结构和功能的无与伦比的信息。在急性期，它有助于诊断AMI及其并发症。它是监测治疗的极佳工具。超声心动图已被证明在患者就诊于急诊科时以及出院前进行风险分层方面很有用。负荷超声心动图拓宽并增强了诊断和预后信息。对比超声心动图有望显示冠状动脉血流。超声心肌组织特征研究显示了区分缺血心肌和梗死心肌的潜力。因此，超声心动图在未来AMI患者的管理中可能会变得越来越重要。
