RESUMEN
Background and Aim: Coronavirus disease 2019 (COVID-19) is a respiratory disorder that can affect many body systems, including the hemostatic system. In this study, we aim to investigate the role of hemostatic system and the blood coagulation in COVID-19. Methods & Materials In this review study, the articles were searched using the keywords COVID-19, Respiratory infection, and Coagulopathy in Google Scholar, PubMed, Google Springer and Science Direct databases. Ethical Considerations: Ethical principles in writing this article were observed in accordance with the guidelines of the National Ethics Committee and the Committee on Publication Ethics (COPE). Results Many changes in the coagulation profile of infected patients were reported, including changes in the platelet count, fibrinogen/fibrin degradation product, D-Dimer, fibrinogen, prothrombin time, and activated partial thromboplastin time. With the increase in the number of patients with COVID-19, several studies found out the occurrence of thrombosis and coagulopathy in patients. Conclusion: Due to the increase in the occurrence of coagulation disorders in patients with COVID-19, the administration of anticoagulants is needed for their treatment;it can play an effective role in improving the prognosis of patients.
