What is the clinical evidence from this study?

Study design: Case Report. Population: Myocardial infarction in aneurysmal coronary artery disease (n=1). Intervention: Multimodality imaging (MRI, CT scan, DSA coronarography). Primary outcome: Diagnosis of myocardial infarction.

What does this research mean for the field?

Multimodality imaging including cardiac MRI and CT angiography can identify underlying coronary aneurysms and distinguish post-infarction acute pericarditis from myocarditis in young patients presenting with acute chest pain. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To describe an atypical case of acute myocardial infarction presenting with cardiac magnetic resonance findings that mimicked acute myocarditis due to post-infarction pericarditis.

Implication

MRI subepicardial LGE supports myocarditis diagnosis in young low-risk patients; leaves open validation in prospective cohorts.

Key Points

To describe an atypical case of acute myocardial infarction presenting with cardiac magnetic resonance findings that mimicked acute myocarditis due to post-infarction pericarditis.
Assessed a 33-year-old male athlete presenting with acute chest pain using initial electrocardiography, serum troponin testing, and early cardiac magnetic resonance imaging within 24 hours of admission.
Performed digital subtraction angiography and computed tomography coronary angiography, followed by repeat magnetic resonance imaging at 12 months.
Initial cardiac MRI revealed T2 hypersignal in the apicolateral territory and bright subepicardial delayed enhancement with pericardial thickening, accompanied by peak troponin of 16 ng/mL and concave-upward ST-segment elevations.
Computed tomography and digital subtraction angiography identified multiple coronary aneurysms involving the left anterior descending, circumflex, and right coronary arteries.
Follow-up cardiac MRI at 12 months confirmed the resolution of subepicardial enhancement alongside classic subendocardial enhancement, establishing the diagnosis of myocardial infarction.

Population

A 33-year-old healthy male martial arts teacher presenting with acute chest pain who was diagnosed with myocardial infarction in aneurysmal coronary artery disease.

Exposure

Magnetic resonance imaging (MRI), computed tomography (CT), and digital subtraction angiography (DSA)

Outcome

Diagnosis of myocardial infarction in aneurismal coronary artery disease

Predominant subepicardial enhancement on MRI can mask an underlying myocardial infarction due to aneurysmal coronary artery disease, presenting initially as acute pericarditis.

Gahide et al. (2008) conducted a case report in Myocardial infarction in aneurysmal coronary artery disease (n=1). Multimodality imaging (MRI, CT scan, DSA coronarography) was evaluated on Diagnosis of myocardial infarction. Multimodality imaging including MRI and CT scan identified multiple coronary aneurysms and confirmed the diagnosis of myocardial infarction in a 33-year-old male presenting with acute chest pain.
