Characterization of Hematological Changes and Coagulopathy Patterns in Iraqi Patients with Post-COVID-19 Syndrome

Background: A Complex Multisystem Disorder Representing A Significant Proportion Of COVID-19 Survivors Emerging evidence indicates that persistent hematological abnormalities and coagulopathy may play a role in the pathophysiology of long COVID symptoms. However, existing data document limited information on the prevalence and patterns of hematological abnormalities in residents of the Middle East, especially Iraq. Objectives: The objectives of this study are to investigate the hematological changes and the patterns of coagulopathy in patients from Iraq who have presented to private clinics in Baghdad with post-COVID-19 syndrome, and to evaluate the risk factors associated with the identified hematological abnormalities. Methods: A cross-sectional survey was conducted at National centre of teaching laboratories / Baghdad medical city between January 2023 and December 2023. We included a sample of 312 patients meeting the World Health Organization (WHO) criteria for post-COVID-19 syndrome; symptoms persisting beyond 12 weeks after acute infection. Complete Blood Counts, Coagulation Profiles, D-dimer levels, Fibrinogen levels, and inflammatory markers were all assessed using comprehensive hematological analysis. The data collected from the above tests were analyzed using appropriate statistical methods, and a p-value of
