A 32-year-old man was admitted with syncope after an episode of chest pain accompanied by fever and myalgia that had occurred for 4 days before admission. At the time of admission, the GCS score equaled 13, and he was confused. Also, he complained about dyspnea and dry cough. Vital signs were as follows: body temperature = 36.8°C, systolic blood pressure = 85/60 mmHg, heart rate = 120/min, and O2 saturation = 80% without oxygenation. The ECG showed sinus tachycardia, low-voltage limb leads, inverted T waves in two limb leads (L1 and aVL), and ST-segment depression in three pericardial leads (V1–V3). The TTE revealed LVEF = 25%, an enlarged end-diastolic diameter of the left ventricle, normal RV size (mild dysfunction), and normal valvular and pericardial function. Moreover, echocardiography demonstrated increased wall thickness. The patient had a positive nasal and oropharyngeal PCR test for COVID-19 as well as the lung CT scan showed diffuse bilateral GGO suggestive of COVID-19.\nThe patient received corticosteroids (methylprednisolone 1 mg/kg/day), broad-spectrum antibiotics (meropenem [500 mg q8 h for 5 days] and doxycycline [200 mg/day]), and remdesivir for COVID-19. The patient was discharged after 2 weeks with an ejection fraction of 45%. Follow-up of the patient for 3 months revealed an LVEF of 45% and normal RV function.
A 14-year-old girl with a history of glucose-6-phosphate dehydrogenase (G6PD) deficiency was admitted with fever, cough, and dyspnea that had occurred since a week before admission. Moreover, she experienced loss of consciousness that had arisen about an hour before admission. Vital signs were as follows: body temperature = 38.2°C, systolic blood pressure = 60/50 mmHg, heart rate = 145/min, and O2 saturation = 60% without oxygenation. Also, the GCS score was 12. The ECG showed sinus tachycardia and low-voltage limb leads. So, she was intubated immediately, and vasopressors were administered. The chest CT scan showed bilateral diffuse GGO and consolidations (Figure ) as well as she had a positive nasal and oropharyngeal PCR test for COVID-19. Furthermore, the patient was anemic (hemoglobin = 6 g/dl). Echocardiography demonstrated an LVEF of 15%, no pleural effusion, normal inferior vena cava, pulmonary arterial pressure of 30 mmHg, and normal LV and RV size. The patient received broad-spectrum antibiotics (meropenem [500 mg] and doxycycline [200 mg/day]), high-dose corticosteroid (methylprednisolone 1 g/day), and remdesivir for COVID-19. However, the patient died in virtue of acute respiratory distress syndrome (ARDS).
