The role of echocardiography in acute pulmonary embolism (PE) remains incompletely defined. Echocardiography cannot reliably diagnose acute PE, and it does not improve prognostication of patients with low-risk acute PE who lack other clinical features of right ventricular (RV) dysfunction. Echocardiography, however, may yield additional prognostic information in higher risk patients and can aid in distinguishing acute from chronic RV dysfunction. Specific echocardiographic markers of RV dysfunction have the potential to enhance prognostication beyond existing risk models. Until these markers are subjected to rigorous prospective studies, the therapeutic utility and economic value of echocardiography in acute PE are uncertain.
超声心动图在急性肺栓塞（PE）中的作用尚未完全明确。超声心动图不能可靠地诊断急性 PE，也不能改善无右心室（RV）功能障碍其他临床特征的低危急性 PE 患者的预后。然而，在高危患者中，超声心动图可能会提供额外的预后信息，并有助于区分急性和慢性 RV 功能障碍。RV 功能障碍的特定超声心动图标志物有可能在现有风险模型之外增强预后。在这些标志物经过严格的前瞻性研究之前，超声心动图在急性 PE 中的治疗效用和经济价值尚不确定。
