THROMBOPROPHYLAXIS IN COVID-19

ABSTRACT

The SARS-CoV-2 pandemic and its specific respiratory pathology has generated extensive research that has highlighted the specific nature of the disease (COVID-19). Thrombotic processes in the macrocirculation and microcirculation were among the first reported, accompanying respiratory (pulmonary) manifestations. Of the COVID-19 complications, thrombosis in the venous system (venous thrombosis and pulmonary embolism) and the atrial system (stroke) are the most numerous and severe in terms of evolution and prognosis. The prophylaxis of thrombotic processes in COVID-19, initially empirical, has gained a scientific basis based on research and experience of clinicians. The current paper presents general data on macro- and microcirculatory thrombosis and the rationale for thromboprophylaxis. Thromboprophylaxis in non-hospitalized COVID-19 patients, "non-critical" and "critical" hospitalized patients and possible post-hospital thromboprophylaxis are presented. Heparins (HGMM and HNF) are the most commonly indicated and used antithrombotic agents. Other antithrombotic agents - antiplatelets and direct anticoagulants (oral - DOAC) have a very limited and possibly negative role in thromboprophylaxis in COVID-19. (English) [ FROM AUTHOR]
