AIM To investigate the diagnostic value of cardiovascular magnetic resonance (CMR) imaging in patients with myocardial infarction with non-obstructive coronary arteries (MINOCA).
METHODS From 2017 to 2019, 26 patients whose coronary angiography results did not show <50% stenosis in any of their coronary arteries underwent CMR imaging.
RESULTS CMR diagnoses included acute myocardial infarction (15 cases), acute myocarditis (3 cases) and Takotsubo cardiomyopathy (3 cases). The remaining patients (5 cases) had either nonspecific findings or could not be classified.
CONCLUSION One-stop CMR allows for etiological identification in most of the patients in this study. CMR imaging may help to differentiate MINOCA with acute myocardial infarction, Takotsubo cardiomyopathy or myocarditis.
