Thrombophilia and risk of VTE recurrence according to the age at the time of first VTE manifestation.

Background: Whether screening for thrombophilia is useful for patients after a first episode of venous thromboembolism (VTE) is a controversial issue. However, the impact of thrombophilia on the risk of recurrence may vary depending on the patient's age at the time of the first VTE.

Patients And Methods: Of 1221 VTE patients (42 % males) registered in the MAISTHRO (MAin-ISar-THROmbosis) registry, 261 experienced VTE recurrence during a 5-year follow-up after the discontinuation of anticoagulant therapy.

Prevalence of established risk factors for venous thromboembolism according to age.

Objective: To date, the factors that contribute to the rise in venous thromboembolism (VTE) risk observed with higher ages remain unknown. Therefore, the aim of the present analysis was to study the distribution of established VTE risk factors in categories of manifestation age in a large cohort of VTE patients.

Methods: Data were taken from the MAISTHRO (MAin-ISar-THROmbosis) registry, a cross-sectional study of patients with acute or documented history of VTE.

Prevalence of thrombophilia according to age at the first manifestation of venous thromboembolism: results from the MAISTHRO registry.

Thrombophilia is a well-established risk factor for a venous thromboembolic event (VTE), and it has been proposed that hereditary thrombophilia may substantially contribute to the development of VTE in young patients. We aimed to analyse the prevalence of thrombophilia with special regard to the age of VTE manifestation. The study cohort consisted of 1490 patients (58% females) with a median age 43 years at the time of their first VTE.
