A 16‐year‐old patient presented with acute myocarditis after gastroenteritis. His ECGs showed STEMI‐like evolutionary changes. Serial troponin measurement was maximum on 3rd day. Echocardiography showed a mildly reduced ejection fraction (45%). He made an uneventful recovery after appropriate treatment. After one‐month follow‐up, his ECG and echo returned to normal.
Gastroenteritis can be complicated by life‐threatening cardiac manifestations. Myocarditis should be considered when a person, without conventional atherosclerosis risks, presents with chest pain, arrhythmia, and cardiogenic shock after gastroenteritis. Timely diagnosis and prompt treatment are crucial to prevent chronic myocarditis and cardiomyopathy.
