Insights
Coronavirus disease 2019 (COVID-19) causes coagulopathy and venous thromboembolism due to systemic inflammation. This review covers COVID-19 coagulopathy
Area of Science:
- Medical research
- Infectious diseases
- Hematology
Background:
- Coronavirus disease 2019 (COVID-19), caused by SARS-CoV-2, is a global pandemic.
- COVID-19 primarily impacts the respiratory system, leading to lung injury and acute respiratory distress syndrome.
- Systemic inflammation is the leading hypothesis for COVID-19's pathophysiology, resulting in coagulopathy.
Purpose of the Study:
- To review the latest evidence on the pathophysiology, diagnosis, and treatment of COVID-19-associated coagulopathy.
- To discuss prophylactic and therapeutic anticoagulation strategies for COVID-19 patients.
- To explore post-discharge prophylaxis and novel treatments for hypercoagulability in COVID-19.
Main Methods:
- Literature review of updated evidence on COVID-19 coagulopathy.
- Analysis of diagnostic approaches for thrombotic complications.
- Evaluation of current and emerging treatment strategies, including anticoagulation.
Main Results:
- COVID-19 patients exhibit a high risk of venous thromboembolism and thrombotic complications.
- Prophylactic anticoagulation is recommended for all hospitalized COVID-19 patients.
- Therapeutic anticoagulation is indicated for high-risk patients or those with established venous thromboembolism.
Conclusions:
- Coagulopathy is a significant complication of COVID-19, increasing the risk of thromboembolic events.
- Anticoagulation strategies, including prophylactic and therapeutic, are crucial for managing COVID-19 patients.
- Further research into novel treatments for hypercoagulability may improve patient outcomes.
Abstract:
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV‑2), is now a global pandemic. This virus primarily affects the respiratory tract and causes lung injury characterized by acute respiratory distress syndrome. Although the pathophysiology of COVID-19 is not yet clear, the most widely accepted mechanism is systemic inflammation. A clinically significant effect of the inflammation is coagulopathy. As a result of this effect, patients are found to have a high risk of venous thromboembolism. Studies have reported a high incidence of thrombotic complications in critically ill patients with COVID-19. In this review, we discuss the most updated evidence on the pathophysiology, diagnosis, and treatment of the coagulopathy of COVID-19. Prophylactic anticoagulation is recommended for all in-patients with COVID-19. Those with a higher risk of developing thromboembolic events or who have already developed venous thromboembolism should be treated with therapeutic anticoagulation. We also discuss post-discharge prophylaxis for high-risk patients and some newly proposed treatments for the hypercoagulability that could improve the outcomes of the affected patients.
