We aimed to study the efficacy of cardiac magnetic resonance imaging (CMR) and intracoronary optical coherence tomography (OCT) in detecting the etiology of myocardial infarction with non-obstructive coronary arteries (MINOCA). A systematic search was conducted in PubMed, Medline, and Cochrane databases. Search terms used: Myocardial infarction, Coronary angiography, Normal coronary arteries, CMR, and OCT. Inclusion criteria was fulfilled by 18 studies. Meta-analysis was performed with 15 studies. A total of 2697 patients were included. The mean age of all the patients was 51.5 and 56.4% were men. CMR established diagnosis in 74% of the patients; 29% had acute myocarditis, 18% had true myocardial infarction and 12% had takotsubo cardiomyopathy. Combining OCT with CMR was better at finding the etiology than either modality individually. The findings of this study conclude that CMR is integral in identifying the etiology of MINOCA. Coupling OCT and CMR is better than either technique individually at finding the cause.
我们旨在研究心脏磁共振成像（CMR）和冠状动脉内光学相干断层扫描（OCT）在检测非阻塞性冠状动脉心肌梗死（MINOCA）病因方面的有效性。我们在PubMed、Medline和Cochrane数据库中进行了系统检索。使用的检索词为：心肌梗死、冠状动脉造影、正常冠状动脉、CMR和OCT。18项研究符合纳入标准。对15项研究进行了荟萃分析。共纳入2697例患者。所有患者的平均年龄为51.5岁，男性占56.4%。CMR在74%的患者中确立了诊断；29%患有急性心肌炎，18%患有真性心肌梗死，12%患有应激性心肌病。与单独使用任何一种方法相比，将OCT与CMR结合起来在寻找病因方面效果更好。本研究结果表明，CMR在确定MINOCA病因方面不可或缺。在寻找病因方面，将OCT和CMR结合使用比单独使用任何一种技术效果更好。
