Coagulation Abnormalities Associated with COVID-19: A Narrative Review

Coronavirus disease 2019 (COVID-19), a viral respiratory illness caused by severe acute respiratory disease coronavirus 2 (SARS-COV-2), has caused in the last 5 years a global pandemic of unprecedented scale in the modern era. Other than the typical respiratory symptoms, patients suffering from moderate to severe COVID-19 are at risk of developing a peculiar systemic coagulopathy, known as COVID-19-associated coagulopathy. In addition to a predominantly hypercoagulable state, COVID-19 patients may experience hemorrhagic complications triggered by the viral infection. The current knowledge on the underlying molecular mechanisms, the laboratory and clinical characteristics of coagulation abnormalities associated with COVID-19, along with their management, will be summarized in this narrative review.
