CMR confirms focal myopericarditis in suspected inferior STEMI with nonobstructive coronary arteries.
Why the study?
Focal myopericarditis is an uncommon inflammatory condition that can present with localized ST-segment elevation and closely mimic STEMI, creating a diagnostic challenge in acute cardiovascular care.

Consider myopericarditis in pleuritic pain with concave ST elevation; leaves open need for validated algorithms to differentiate from STEMI.
BACKGROUND: Focal myopericarditis is an uncommon inflammatory condition that may present with localized ST-segment elevation and closely mimic ST-segment elevation myocardial infarction (STEMI), creating a diagnostic challenge in acute cardiovascular care. CASE SUMMARY: A 53-year-old man presented with acute pleuritic chest pain radiating to the back, worsened by inspiration and the supine position, and relieved by sitting upright. Electrocardiography demonstrated concave ST-segment elevation in the inferior leads, raising suspicion for inferior STEMI. Urgent coronary angiography revealed nonobstructive coronary artery disease without a culprit lesion. Persistent ST-segment elevation and atypical clinical features prompted cardiac magnetic resonance (CMR) imaging, which demonstrated myocardial edema, subepicardial late gadolinium enhancement, and mild pericardial effusion, confirming focal myopericarditis. DISCUSSION: This case emphasizes the importance of integrating clinical, angiographic, and CMR findings to distinguish focal myopericarditis from STEMI and ensure appropriate management. TAKE-HOME MESSAGE: CMR imaging is essential for differentiating inflammatory myocardial injury from acute myocardial infarction.
