      Identification of patients at risk of major bleeding is pivotal for optimal management of anticoagulant therapy in venous thromboembolism (VTE). Studies have suggested that D-dimer may predict major bleeding during anticoagulation; however, this is scarcely investigated in VTE patients. We aimed to investigate the role of D-dimer, measured at VTE diagnosis, as a predictive biomarker of major bleeding. ...
    • Hospitalization as a trigger for venous thromboembolism – Results from a population-based case-crossover study 

      Bjøri, Esben; Johnsen, Håkon Sandbukt; Hansen, John-Bjarne; Brækkan, Sigrid Kufaas (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-21)
      <i>Background</i> - Previous studies have reported that around 50% of patients with venous thromboembolism (VTE) has undergone recent hospitalization. However, studies on the impact of hospitalization as a trigger factor for VTE are limited.<p><p> <i>Objectives</i> - To investigate the impact of hospitalization with and without concurrent immobilization as a trigger factor for VTE.<p><p> ...
    • Prothrombotic genotypes and risk of major bleeding in patients with incident venous thromboembolism 

      Johnsen, Håkon Sandbukt; Bjøri, Esben; Hindberg, Kristian; Brækkan, Sigrid Kufaas; Morelli, Vania Maris; Hansen, John-Bjarne (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-22)
      <i>Background</i> - Genotypes associated with venous thromboembolism (VTE) may protect against bleeding due to a hypercoagulable state. Whether the risk of major bleeding is reduced in parallel with an increasing number of prothrombotic genotypes during anticoagulant treatment in VTE remains unknown.<p> <p><i>Objectives</i> - To investigate the association between multiple prothrombotic genotypes ...
    • Triggers and risk factors of first and recurrent venous thromboembolism 

      Bjøri, Esben (Doctoral thesis; Doktorgradsavhandling, 2020-01-29)
      Venous thromboembolism (VTE), encompassing both deep vein thrombosis and pulmonary embolism, is a major public health concern due to substantial morbidity and mortality. Around half of all VTE cases are hospital-related. Importantly, VTE also has life-long implications, as a large proportion of VTE-patients suffer either a recurrent event or chronic complications. The first aim of the thesis was to ...
