Abstract: Pulmonary embolism is a common pulmonary vascular disease with high rates of misdiagnosis and missed diagnosis. Early identification，diagnosis and treatment are essential to improve the prognosis of patients. Although pulmonary angiography is deemed as the gold standard for the diagnosis of pulmonary embolism，it has been gradually replaced by CT pulmonary angiography due to high cost，invasion and risk of radiation exposure. However，if patients with suspected pulmonary embolism are not effectively evaluated，it may lead to overuse of examinations，and waste of medical resources，as well as an increase in patients' risk of exposure to radiation. There are a variety of scoring models that can be used as assistant tools for effectively ruling out suspected pulmonary embolism. But those using the traditional scoring method are not easily to be promoted due to complexity. In contrast，the YEARS algorithm，a recently emerged model，is simple and mnemonic，which can be used to safely，effectively and rapidly exclude suspected pulmonary embolism，and is easily to be promoted. But its diagnostic value still needs to be verified since studies on its clinical application are limited. This article reviews clinical studies of YEARS algorithm，offering new ideas for pulmonary embolism diagnosis.

摘要： 肺栓塞是一种误诊率、漏诊率极高的常见肺血管病，早期识别、早期诊治对改善患者预后至关重要。肺动脉造影是确诊肺栓塞的“金标准”，因其昂贵、有创、有辐射暴露风险，在临床已经逐渐被CT肺血管造影取代。但可疑肺栓塞的患者如果未经有效评估，可能导致过度检查及不必要的医疗资源浪费，也增加了患者辐射暴露的风险。为了有效筛查可疑肺栓塞，目前有多种评分模型对可疑肺栓塞进行评估，但传统评分法相对较复杂，不易在临床工作广泛推广使用。YEARS评分是近年来针对可疑肺栓塞进行评估的新型评分模型，其是一种简单、快速的评估肺栓塞可能性的工具，可以安全有效排除可疑肺栓塞患者，该评分标准更为简便，易于记忆和临床推广。但因目前其临床应用研究有限，有待进一步在临床验证该评分的诊断价值。本文就YEARS评分的临床研究做一综述，以期为肺栓塞的诊断提供新思路、新方法。
