Pulmonary embolism (PE) is a common clinical entity, which most clinicians will encounter. Appropriate risk stratification of patients is key to identify those who may benefit from reperfusion therapy. The first step in risk assessment should be the identification of hemodynamic instability and, if present, urgent patient consideration for systemic thrombolytics. In the absence of shock, there is a plethora of imaging studies, biochemical markers, and clinical scores that can be used to further assess the patients' short-term mortality risk. Integrated prediction models incorporate more information toward an individualized and precise mortality prediction. Additionally, bleeding risk scores should be utilized prior to initiation of anticoagulation and/or reperfusion therapy administration. Here, we review the latest algorithms for a comprehensive risk stratification of the patient with acute PE.

肺栓塞 (PE) 是一种常见的临床疾病，大多数临床医生都会遇到。对患者进行适当的风险分层是确定可能从再灌注治疗中受益的关键。风险评估的第一步应该是识别血流动力学不稳定，如果存在，患者应紧急考虑全身溶栓剂。在没有休克的情况下，有大量的影像学检查、生化标志物和临床评分可用于进一步评估患者的短期死亡风险。综合预测模型包含更多信息，以实现个性化和精确的死亡率预测。此外，应在开始抗凝和/或再灌注治疗之前使用出血风险评分。这里，
