Splenic Infarction and Myocardial Infarction in A Patient with COVID-19 on Anticoagulant Therapy with Normal D-Dimer Levels

Many studies have shown that COVID-19 can progress with coagulopathy and multisystem thrombotic pathologies. This article presents the case of a patient who, 9 days after laboratory-confirmed coronavirus pneumonia against the background of anticoagulant therapy, was diagnosed with splenic infarction in combination with acute myocardial infarction during subsequent hospitalization. Prevention of thrombosis with prophylactic doses of low molecular weight heparin in hospitalized patients with COVID-19 may not be sufficient to prevent the development of coagulopathy. Abdominal visceral thromboembolism should be suspected in a COVID-19 positive patient with abdominal pain despite anticoagulant therapy and normal D-dimer levels.
