[评论] 更快的肌钙蛋白检测，急诊科停留时间不变：急性冠脉综合征评估的下一步是什么？
摘要
急诊科过度拥挤和入院受阻现已成为全球急性医院面临的最严重后果性患者安全问题之一。1 相关危害是可测量的、呈剂量依赖性的，并且超过约5小时后没有明确的安全阈值。2 疑似心肌梗死就诊患者在急诊科负担中占很大且可能可调节的比例。胸痛是美国成人急诊就诊的第二大常见原因，每年约800万次就诊，约占所有急诊就诊的5.5%。

Emergency department overcrowding and access block are now among the most consequential patient-safety problems facing acute hospitals globally.1 The associated harm is measurable, dose-dependent, and has no clearly safe threshold beyond approximately 5 h.2 Patients presenting with possible myocardial infarction constitute a large and possibly modifiable share of the emergency department burden. Chest pain is the second most common reason for adult emergency department attendance in the USA, accounting for approximately 8 million encounters annually and around 5·5% of all emergency department visits.
