Why the study?
To describe a case presenting as acute myocardial infarction caused by lymphocytic myocarditis and explore the relationship between acute myocardial infarction and lymphocytic myocarditis.
Answers are grounded in this paper and cite their sources.
Lymphocytic myocarditis can present as acute myocardial infarction despite normal coronary arteries, and immunosuppressive therapy may be beneficial in virus-negative cases.
We report a case that presented as acute myocardial infarction (AMI) caused by lymphocytic myocarditis (LM), and explore the relationship between AMI and LM. We also performed a literature search to identify publications that previously reported LM-associated myocardial infarction. Coronary angiography of our patient revealed normal coronary arteries. However, a perfusion-metabolism mismatch in the apex and mid-inferior walls supported the diagnosis of AMI, and right ventricular septal endomyocardial biopsy showed LM. Extensive viral serological tests were negative for an infectious etiology. Immunosuppressive therapy may be beneficial in patients with high-risk myocarditis who are pathologically confirmed to be virus-negative.
