Conclusion:
The results of the present study indicated that coagulation disorders
are more prevalent in patients with severe forms of COVID-19. It was
also found that serum D-dimer level is positively associated with
mortality. Although coagulation disorders in COVID-19 patients are still
being investigated, the evidence thus far suggests that thrombotic
coagulation disorder is quite prevalent in severe cases of COVID-19. The
results also indicated that D-dimer has higher sensitivity in comparison
with other coagulation markers and is of greater value in severity.
Compared to the high prevalence of thrombotic events, bleeding is not
that common; therefore, standard anticoagulant therapy is highly
recommended.
