Does Fibrin Structure Contribute to the Increased Risk of Thrombosis in COVID-19 ICU Patients?

Introduction: SARS-CoV-2 is responsible for a global pandemic, with almost 200 million confirmed cases. SARS-CoV-2 infection can lead to various disease states, from only mild symptoms in the majority of cases to severe disease, which is associated with an increased incidence of venous thromboembolism (VTE). We hypothesized that an altered fibrin network structure contributes to VTE in COVID-19 patients by affecting thrombus stability and fibrinolysis sensitivity. By studying the fibrin network of COVID-19 patients, we aimed to unravel the mechanisms that contribute to the increased risk of VTE in COVID-19 patients.
