It has been previously estimated that the risk of venal thrombosis (VTE) among people hospitalised with COVID-19 is around 9% while the risk of an or arterial thrombosis (ATE) is 4%. However, little data exists for these events in patients who have not been admitted to hospital.
A new study published in the Lancet Infectious Diseases, estimates the incidence of VTE and ATE among almost 1 million people with COVID-19, using routinely collected data from across Europe. The study found that for people with COVID-19, the risks ranged from 0.2% to 0.8% for VTE. For ATE it was from 0.1% to 0.8%.
Incidence of these events increased to 4.5% and 3.1% for those hospitalised with COVID-19. Meanwhile, 90-day mortality was between 1.1% and 2.0% among COVID-19 cases and increased to 14.6% for those hospitalised.
Results also showed that being male was generally associated with an increased risk of VTE, ATE, and death, as were various comorbidities and prior medications.
