What is the risk of a first thromboembolic event in asymptomatic carriers of high-risk antiphospholipid antibody profile?
According to a multicenter prospective study conducted by Pengo et al. (2011), the incidence of a first thromboembolic event in asymptomatic carriers of high-risk antiphospholipid antibody profile is not well known. However, the study found that the risk of a first thromboembolic event is increased in patients with antiphospholipid antibodies, particularly those with high-risk profiles.
