Coagulopathy and thrombosis associated with coronavirus disease 2019 (COVID-19) represent a major issue in the management of this disease. In the past months, clinical studies have demonstrated that COVID-19 patients present with a particular hypercoagulable state, in which a markedly increased D-dimer concomitant with increased levels of fibrinogen are observed. This hypercoagulable state leads to an increased risk of thrombosis, which seems to be higher among those patients with critical symptoms of COVID-19. The best therapeutic approach to prevent thrombotic events in COVID-19 has not been determined yet and several questions regarding thromboprophylaxis therapy, such as the time to initiate anticoagulation, type of anticoagulant and dose regimen, have emerged among physicians. To address these concerns, several medical societies have published position papers to provide the opinion of thrombosis experts on the management of coagulopathy and thrombosis associated with COVID-19. In line with this, the Latin America Cooperative Group of Hemostasis and Thrombosis (Grupo CLAHT) has constituted a panel of experts in thrombosis and hemostasis to discuss the available data on this topic. The aim of this review is to summarize the current evidence regarding hemostatic impairment and thrombotic risk in COVID-19 and to provide a carefully revised opinion of Latin American experts on the thromboprophylaxis and management of thrombotic events and coagulopathy in patients with suspected COVID-19.
