Updated definitions of myocardial infarction (MI) reflect research on measuring cardiac troponin to diagnose MI. Elevations of this biomarker indicate cardiac injury but not always an acute coronary syndrome. Clinical judgment is needed to interpret increasingly sensitive biomarker assays appropriately. Here, we review the new MI definitions and the various causes of elevated troponin to enable physicians to differentiate acute coronary syndromes from other conditions.
更新的心肌梗死 (MI) 定义反映了使用心肌肌钙蛋白测量来诊断 MI 的研究。该生物标志物的升高表明心脏损伤，但并不总是急性冠状动脉综合征。需要临床判断才能适当解释日益敏感的生物标志物检测。在这里，我们回顾了新的 MI 定义和导致肌钙蛋白升高的各种原因，以使医生能够区分急性冠状动脉综合征与其他情况。
