A 25-year-old male with no past medical history presented with 1 day of chest pain. The patient had exercised with high intensity for a bodybuilding competition. He had fever, malaise, sore throat, and cough 1 week before presentation. He was tachycardic and tachypneic. Cardiac examination was unremarkable. Electrocardiogram showed diffuse ST segment elevation. Laboratory results showed leukocytosis, creatinine kinase 3078 unit/L, and troponin I 78.06 ng/mL. Coronary angiography revealed no occlusion. Echocardiogram showed ejection fraction of 45% with global hypokinesis. The next day, the patient became dyspneic, hypoxic, and hypotensive. Chest X-ray showed pulmonary edema requiring intubation for respiratory failure. Inotropic support and intra-aortic balloon pump were started. A viral panel was ordered and antibody titer of coxsackievirus B type 4 was ≥1:640. On obtaining further history, it was found that he took liothyronine 75 mcg daily for 3 weeks. Thyroid-stimulating hormone was 0.015 U/mL and free T3 was 4.4 ng/mL. Burch-Wartofsky score was 75. Methimazole and hydrocortisone were started.
