Risk of VTE recurrence quantified
Young, relatively healthy patients with a first spontaneous episode of venous thrombembolism have a low 5-year risk of recurrence and death, US researchers report.
A University of California team followed up 3,456 patients aged 18-56 years with idiopathic venous thromboembolism and no more than one comorbid condition.
The rate of recurrent venous thromboemboloism was 13.1% per year for the first six months after the index episode, falling to 2.9% per year for the remaining 6-60 months. Over an average follow-up of 3.2 years, 3.4% of the patients died.
