GRACE评分是目前临床上用于对急性冠脉综合征(ACS)患者进行危险评估、判断预后并进而指导其治疗策略的重要工具之一。但是，GRACE评分在使用的便捷性、评估的准确性等方面仍然存在提升的空间。近年来，人们一直在探索改良GRACE评分指标设置的合理方案，在提高GRACE评分的准确性、方便该评分在急诊的应用以及增强该评分对低危ACS患者的识别与危险评估能力等方面取得了很大的进展。 The GRACE score is one of the most important tools clinically used to assess the risk of patients with acute coronary syndrome (ACS), determine the prognosis and then guide the treatment strategy. However, the GRACE score still has room for improvement in terms of ease of use and accuracy of assessment. In recent years, people have been exploring a reasonable plan to improve the setting of GRACE scoring index, which has been achieved in improving the accuracy of the GRACE score, facilitating the application of the score in the emergency department, and enhancing the ability of the score to identify and assess the risk of low-risk ACS patients Great progress.
