Patient: Male, 50-year-old Final Diagnosis: Acute myopericarditis Symptoms: Abdominal pain • chest discomfort Medication: — Clinical Procedure: — Specialty: Cardiology Objective: Background: Case Report: Conclusions: Unusual clinical course Triangular QRS-ST-T waveform (TW) electrocardiography pattern has been found to be associated with poor prognosis in patients with ST-segment elevation myocardial infarction (STEMI). It identifies a subset of patients at high risk of both ventricular fibrillation and cardiogenic shock, with high in-hospital mortality. Therefore, ag-gressive treatment is needed in patients presenting with this electrocardiography pattern. However, this pattern is rarely present in non-ischemic cardiac diseases. We report the case of a 50-year-old man who came to our emergency room with a chief complaint of gastroin-testinal problems and partial bowel obstruction. After failure of initial conservative treatment, laparotomy was planned. Just before the surgery, the patient felt a non-specific chest discomfort and showed ST-segment elevation on ECG and slight elevation of cardiac enzyme. He was then treated for STEMI with an intravenous throm-bolytic. However, the degree of ST-segment elevation further increased and showed a TW pattern. Transthoracic echocardiography revealed a moderate pericardial effusion with normal ejection fraction and a normokinet-ic left ventricle; hence, a diagnosis of acute myopericarditis was made. After treatment with low-dose steroid and colchicine, his symptoms improved, the electrocardiography pattern returned to normal, and the gastro-intestinal symptoms resolved. To the best of our knowledge, this is the first case report of an acute myopericarditis presenting with a TW electrocardiography pattern. Myopericarditis should always be considered in the differential diagnosis of acute chest pain and ST segment electrocardiography changes, including TW pattern. The use of echocardiography can help determine the diagnosis of myopericarditis.
