Dengue fever is one of the most common vector-borne viral infections in tropical countries. Myocarditis is an uncommon complication of severe dengue fever. Sometimes, dengue myocarditis masquerades as acute myocardial infarction. We report here a case of a 22-year-old female, who presented with acute chest pain five days after the onset of a febrile episode. Initially she was diagnosed as acute myocardial infarction depending on the biochemical and echocardiography evidence. However, later investigation confirmed she was suffering from myocarditis due to dengue fever, which mimicked acute myocardial infarction. A Medline search revealed only few other reported cases of dengue myocarditis that mimicked of acute myocardial infarction.
Key words: Acute myocardial infarction, Dengue fever, Myocarditis.
