Impact of COVID-19 on coagulation function and stroke risk


  • Coagulation function is altered in patients with coronavirus disease 2019 (COVID-19), and COVID-19 increases the risk of stroke, particularly in those with existing cerebrovascular disease.

Why this matters

  • There has been little research on the relationship between COVID-19 and stroke risk, or on coagulation function as a determinant of stroke risk.

  • Results of this study show that stroke risk is increased in patients with severe COVID-19, especially those with existing cerebrovascular disease, warranting increased attention to this population and potential treatment approaches.
