Late stent thrombosis and acute ST-elevation myocardial infarction in a case affected with COVID-19: A rare manifestation

ABSTRACT

A 65-year-old male was introduced with a history of percutaneous coronary intervention 2 years ago who received Aspirin and Plavix. He was referred for coronary angiography after receiving thrombolytic therapy for ST-elevation myocardial infarction in precordial leads. On admission, he had dyspnea with low oxygen saturation, leukocytosis, lymphopenia, elevated C-reactive protein, and cardiac troponin levels. Transthoracic echocardiography demonstrated left ventricular ejection fraction (LVEF) of 25% and pulmonary artery pressure of 45 mmHg. A small thrombus at the site of the previously deployed stent was noticeable at coronary angiography. The chest computed tomography depicted significant involvement of the lungs manifested by peripheral ground-glass opacifications. A positive polymerase chain reaction confirmed coronavirus infection. He was oxygen dependent for 1 week. Gradually, his respiratory distress improved and his LVEF reached to 30% after discharge.
