CMR Reclassifies the Majority of Patients with Suspected MINOCA and non MINOCA.

In a large single-centre cohort of patients presenting with acute coronary syndrome and unobstructed coronary arteries, most patients had a non-MINOCA diagnosis (73%) (myocarditis, TakoTsubo, cardiomyopathies or normal CMR/non-specific findings), whilst only a minority had confirmed MINOCA (27%). Performing CMR led to reclassifying patients' diagnosis in 78% of cases, thus confirming its important clinical role and underscoring the clinical challenge in diagnosing MINOCA and non MINOCA conditions.
