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.

We consecutively selected patients who were suspected of myocardial infarction with concomitant CAG from January 2019 to June 2024 at the Affiliated Hospital of Xuzhou Medical University. All patients completed CMR during hospitalization. hsTnT peak was above the 99th percentile and CAG less than 50% in all patients.
