Myocardial injury secondary to acute pulmonary embolism - a case report

A case of a 37-year-old male admitted to the hospital due to dyspnea and chest pain is presented. Electrocardiogram showed negative T waves in V1 and V2 as well as subtle ST segment elevation in all precordial leads. Cardiac enzymes were moderately elevated. The initial diagnosis was myocarditis or acute coronary syndrome, however, transthoracic echocardiography showed a marked right ventricular overload which suggested acute pulmonary embolism. The latter diagnosis was confirmed by transesophageal echocardiography which revealed thrombosis of both left and right pulmonary arteries. The patient received thrombolysis and anticoagulants, and his condition improved. He was discharged home and the course of a six-month follow-up was uneventful.
