Early CMR in Acute MI (Early AMI-CMR)
Exploring the Application and Value of Cardiac Magnetic Resonance in Acute Myocardial Infarction
The goal of this observational study is to evaluate the clinical utility of cardiac magnetic resonance (CMR) in patients with acute myocardial infarction (AMI). This is a retrospective and prospective cohort study that has already enrolled a number of patients and will continue to enroll additional patients on a rolling basis.
The main question it aims to answer is:
How does CMR, performed acute phase, contribute to risk stratification, prognostic assessment, and long-term clinical management in patients with AMI?
Participants who have had an AMI will undergo CMR within one week of symptom onset. After discharge, they will be regularly followed up at 1, 3, 6, 9, and 12 months, and then every 6 months thereafter. Clinical outcomes will be collected during each follow-up visit.

AMI
|
Cardiovascular magnetic resonance imaging will be used to assess cardiac structure, function, myocardial injury, infarct size, late gadolinium enhancement, microvascular obstruction, and other CMR-derived parameters.
This is an observational cohort study, and no diagnostic test or treatment will be assigned by the investigators.
CMR examinations have been or will be performed as part of routine clinical evaluation according to clinical indications.
