A 28-year-old man was admitted with chest pain, fever, and dry cough that had arisen for 3 days before admission. Vital signs were as follows: body temperature = 36.8°C, systolic blood pressure = 100/60 mmHg, heart rate = 92/min, and O2 saturation = 92% without oxygenation. The ECG illustrated sinus rhythm with ST-segment elevation and Q waves in precordial leads. Also, angiography showed normal coronary arteries. Echocardiography revealed LVEF = 30%–35%, hypokinesis in the anterior wall, normal LV size as well as normal RV size and function. Lung CT scan showed a bilateral GGO pattern (Figure ) as well as the patient had a positive nasal and oropharyngeal PCR test for COVID-19. The patient received broad-spectrum antibiotics (meropenem [500 mg q8 h for 5 days] and doxycycline [200 mg/day]), corticosteroid (methylprednisolone 1 mg/kg/day), and remdesivir for COVID-19 for 7 days. It is worth mentioning that LVEF improved to 45%–50% after treatment. He recovered within 3 days and was discharged in a satisfying condition. Follow-up of the patient for 3 months revealed LVEF of 45%–50% and a normal cardiac function.
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.
