<p><strong>Materials ant methods.</strong> 46 consecutives patients presented with myocardial infarction without evidence of obstructive coronary disease on angiography between January, 1 2018 and October 1, 2019 were included in the study. All patients underwent CMR within 10 days after admission. MRI was performed on 1.5 T Magnetic Resonance Imaging (MRI) using comprehensive protocol (T2-images, Cine-CMR, late gadolinium enhancement (LGE)).</p>
<p><strong>Results.</strong> CMR revealed myocardial infarction (MI) pattern in 14 patients (30.4%), myocarditis in 12 (26.1%), hypertrophic cardiomyopathy in 6 (13.1%). In 14 patients (30.4%) no LGE was observed. Notably in 2 patients without LGE features of takotsubo syndrome were noted. Mean age was significantly lower in patients with MI versus patient with non-ischemic causes of MINOCA (56.112.3 vs 64.612.8; <em>p</em>=0.04). ST elevation at admission frequency didnt differ between MI and non-ischemic patients (35.7% vs 25.0%; <em>p</em>=0.76). However MI patients had significantly increased troponin level, 0.87 [0.22; 1.85] vs 0.22 [0.07; 0.38]; <em>p</em>=0.008. CMR allowed to establish the prcised clinical diagnosis in 73.9% of the cases.</p>
<p><strong>Conclusion.</strong> Clinical data doesnt allow to differentiate ischemic or non-ischemic causes of MINOCA. However, CMR establish the correct diagnosis in most cases.</p>cardiovascular magnetic resonancemyocardial infarction with nonobstructed coronary arteriesacute coronary syndrometroponinмагнитно-резонансная томографияинфаркт миокарда без обструктивного поражения коронарных артерийMINOCAострый коронарный синдромтропонин[Ibanez B, James S, Agewall S, et al. 2017 ESC Guidelines for the management of acute myocardial infarction in patients presenting with ST-segment elevation: The Task Force for the management of acute myocardial infarction in patients presenting with ST-segment elevation of the European Society of Cardiology (ESC).
