Acute myocardial infarction in a child with myocardial bridge
Journal Title: World Journal of Emergency Medicine - Year 2011, Vol 2, Issue 1
Abstract
BACKGROUND: Myocardial infarction (MI) is rare in children, and Kawasaki disease is now recognized as the main cause for MI. In this report, we present a child with MI caused by myocardial bridge (MB). METHODS: A 7.5-year-old boy was admitted to Weifang People’s Hospital on September 16, 2008 for heart disease. By electrocardiogram, coronary CT angiography, emission computed tomography, and other examinations, he was initially diagnosed as having (1) acute inferior myocardial infarction and extensive anterior myocardial infarction; (2) fulminant myocarditis; or (3) coronary myocardial bridge. He was treated with oxygen, thrombolysis, myocardial nutrition, vitamin C (4.0 g per time), dexamethasone (7.5 mg per time), a large dose of gamma globulin, and interferon. RESULTS: Myocardial enzymes, liver function, C-reactive protein, and troponin-I returned to normal at 21 days after treatment. At 29 days, electrocardiogram indicated that II, III, aVF, V4 - V6 leads had abnormal Q wave, and ST-T changed. The patient was discharged. CONCLUSION: Myocardial bridge may be one of the causes of MI in children.
