1、2022年ACC急性胸痛专家共识十大要点2022美国心脏病学会的这份急性胸痛专家共识体现了以高敏肌钙蛋白检测为中心的临床决策路径（CDP）,但没有涉及到如何治疗，其内容主要有以下10个要点：1、心电图仍然是评估胸痛的最佳初始检查手段，因其快速、廉价并能提供关键的诊断和预后信息。建议进急诊室后10分钟内完成心电图检查，对高度怀疑ACS的患者应短时间（没有讲具体几分钟）后进行心电图复查。STEMIorSTEMIequiva1.ent*4Manageasper2013ACCF/AHASTEMIguide1.ineT-、 IschemicST-segmentdepressionorT-waveinve
