Abstract

Myocardial injury after noncardiac surgery (MINS) and perioperative myocardial injury are associated with increased morbidity and mortality. Both are diagnosed by a perioperative increase in troponin, yet there is controversy if MINS is a genuine myocardial insult. We applied postoperative cardiovascular magnetic resonance T2 mapping techniques to visualise acute myocardial injury (i.e. oedema) in six patients with multiple cardiovascular risk factors who underwent aortic surgery. The burden of myocardial oedema was substantially higher in four patients with elevated troponin qualifying for MINS, compared with patients without MINS. The data and images suggest that MINS represents genuine myocardial injury.

非心脏手术后心肌损伤的可视化：使用术后心血管磁共振成像的病例系列。

非心脏手术后心肌损伤（MINS）和围手术期心肌损伤与发病率和死亡率的增加有关。两者都是通过围手术期肌钙蛋白的升高来诊断的，但 MINS 是否是真正的心肌损伤还存在争议。我们应用术后心血管磁共振 T2 映射技术观察了六名接受主动脉手术的具有多种心血管风险因素的患者的急性心肌损伤（即水肿）。与未接受 MINS 的患者相比，四名肌钙蛋白升高且符合 MINS 条件的患者的心肌水肿程度要高得多。这些数据和图像表明，MINS 代表了真正的心肌损伤。

期刊介绍： The British Journal of Anaesthesia (BJA) is a prestigious publication that covers a wide range of topics in anaesthesia, critical care medicine, pain medicine, and perioperative medicine. It aims to disseminate high-impact original research, spanning fundamental, translational, and clinical sciences, as well as clinical practice, technology, education, and training. Additionally, the journal features review articles, notable case reports, correspondence, and special articles that appeal to a broader audience. The BJA is proudly associated with The Royal College of Anaesthetists, The College of Anaesthesiologists of Ireland, and The Hong Kong College of Anaesthesiologists. This partnership provides members of these esteemed institutions with access to not only the BJA but also its sister publication, BJA Education. It is essential to note that both journals maintain their editorial independence. Overall, the BJA offers a diverse and comprehensive platform for anaesthetists, critical care physicians, pain specialists, and perioperative medicine practitioners to contribute and stay updated with the latest advancements in their respective fields.
