Myocardial infarction in a young man due to coronary artery aneurysms after an undiagnosed Kawasaki disease.

BACKGROUND: Kawasaki disease usually affects infants and young children. It often goes unrecognized in adults due to varying symptoms and lack of definite diagnostic criteria. OBJECTIVES: To describe the potential for acute myocardial infarction as a complication of antecedent Kawasaki Disease (KD). CASE REPORT: We describe a case of a 19-year-old man who presented to the Emergency Department (ED) with an acute myocardial infarction that was subsequently determined to be the result of previously untreated KD. CONCLUSION: Kawasaki disease can cause coronary complications in a teenager. A high level of suspicion in the ED can help in proper management of these patients.
