Why the study?
Myocarditis mimicking STEMI presents a major diagnostic challenge, especially without prodromal flu-like symptoms or recent viral illness.
Cardiac MRI is a crucial non-invasive imaging modality to differentiate acute myocarditis from STEMI in young patients presenting with acute chest pain and ST-segment elevations.
Requires vigilance for myocarditis in STEMI mimics; leaves open routine cardiac MRI adoption pending prospective data.
Myocarditis can have a variable clinical presentation, ranging from asymptomatic to full-blown fulminant heart failure with severe left ventricular dysfunction or acute coronary syndrome (ACS) even ST-Elevation Myocardial Infarction (STEMI). Clinically myocarditis mimicking STEMI can present physicians with a great diagnostic challenge, especially in the absence of pro-dormal flu-like symptoms or a recent viral illness. Cardiac MRI has demonstrated superiority in detecting myocardial abnormalities and differentiating patients with myocarditis and from those with true STEMI.
