Summary

This is a single-center retrospective observational study in which we consecutively selected patients diagnosed with acute myocardial infarction from September 2019 to March 2024 at the Affiliated Hospital of Xuzhou Medical University. Inclusion criteria: 1. CMR was completed during all hospitalizations; 2. complete clinical data; 3. received continuous cardiac monitoring during hospitalization. Exclusion criteria: 1. unclear or non-compliant CMR images; 2. previous history of myocardial infarction; 3. malignant tumors diseases. Dedicated cardiovascular imaging software CVI42 (cvi42® version 5.13.5, Circle Cardiovascular Imaging, Canada) was used for image analysis. LA strain was obtained by cardiac MRI feature tracking. Patient prognosis was obtained through chart notes and telephone follow-up. Major events included atrial fibrillation, ischemic stroke, and all-cause mortality.
