Cardiac Magnetic Resonance, Extracellular Volume, Myocardial Infarction with Nonobstructive Coronary Arteries, Strain
Conditions
Brief summary
MINOCA is accompanied by a worse prognosis, which is related to the inability to clarify the etiology.CMR has been explicitly recommended by guidelines as an etiologic diagnostic tool for MINOCA. Although CMR-related parameters, such as strain and ECV, have been shown to be associated with prognosis in patients with myocardial infarction. However, the relationship between CMR-strain or ECV and MINOCA is unclear. The aim of this study was to investigate the characterization of CMR-strain or ECV in patients with MINOCA and the relationship with prognosis.
