摘要

冠状动脉非阻塞性心肌梗死(myocardial infarction without obstructive coronary artery, MINOCA)是指在即冠状动脉管腔面积狭窄≤50%的情况下发生的心肌梗死(myocardial infarction, MI),占总MI的1%~14%。MINOCA的病因复杂多样,正确诊断并明确MINOCA的潜在病因,对于指导后续临床管理至关重要。基于心肌组织特征成像的独特优势,非侵入性的心脏磁共振(cardiac magnetic resonance,CMR)检查在MINOCA患者管理中的价值已被广泛认可。CMR检查可排除类似MI的疾病,如心肌炎、应激心肌病,明确导致MINOCA的潜在病因,是诊断流程中的必要检查手段,有助于减少MINOCA的过度诊断、误诊以及真性MINOCA的漏诊。目前已被美国心脏学会(American Heart Association,AHA)及欧洲心脏学会(European Society of Cardiology,ESC)推荐为MINOCA管理流程中必不可少的检查手段。此外,与冠状动脉阻塞患者相比,MINOCA患者的短期预后较好,但在长期随访中MINOCA患者出现不良预后的风险增加,有必要对MINOCA患者的预后及风险分层提高重视,纳入管理流程。传统的MI预后评价系统对MINOCA患者并不完全适用,CMR检查可为MINOCA患者的预后评估提供有价值的信息。当前,对于CMR在MINOCA患者管理中的应用,国内尚无标准化规范、指南。本文旨在对CMR技术在MINOCA临床管理中的应用规范和预后价值进行介绍,为临床提供参考,以增进对这种特殊MI病变的理解和管理。

Abstract

Myocardial infarction without obstructive coronary artery (MINOCA) refers to myocardial infarction (MI) that occurs when the lumen area of coronary artery stenosis is ≤50%, accounting for 1% to 14% of the total MI. The etio-logy of MINOCA is complex and diverse, and accurate diagnosis and identification of the potential causes of MINOCA are crucial for guiding subsequent clinical management. Based on the unique advantages of myocardial tissue imaging, non-invasive cardiac magnetic resonance (CMR) examination has been widely recognized for its value in the management of MINOCA patients. CMR can be used to exclude diseases similar to MI, such as myocarditis and stress-induced cardio-myopathy, and identify the potential causes of MINOCA. It is a necessary diagnostic tool in the diagnostic process, helping to reduce overdiagnosis, misdiagnosis, and missed diagnosis of true MINOCA. Currently, it has been recommended by the American Heart Association (AHA) and the European Society of Cardiology (ESC) as an essential examination method in the MINOCA management process. In addition, compared with patients with coronary artery occlusion, MINOCA patients have a better short-term prognosis, but the risk of poor prognosis increases in long-term follow-up. It is necessary to pay more attention to the prognosis and risk stratification of MINOCA patients and management process. The traditional MI prognosis evaluation system is not entirely applicable to MINOCA patients, and CMR can provide valuable information for the prognosis evaluation of MINOCA patients. Currently, there are no standardized norms or guidelines for the application of CMR in the management of MINOCA patients in China. This article aims to review the application norms and prognostic value of CMR technology in clinical management of MINOCA, providing reference for clinical practice and enhancing understanding and management of this special MI lesion.
