      <i>Background</i> - Previous studies have shown increased mortality in venous thromboembolism (VTE) patients with chronic obstructive pulmonary disease (COPD), but it is unknown to what extent the association is influenced by the severity of COPD and physical inactivity.<p> <p><i>Objectives</i> - This article investigates whether COPD, and stages of COPD, influenced the risk of mortality after a ...
    • Impact of Chronic Obstructive Respiratory Disease (COPD), respiratory symptoms and oxygen saturation on the risk of incident venous thromboembolism (VTE) and VTE-related mortality in a general population 

      Børvik, Trond (Doctoral thesis; Doktorgradsavhandling, 2019-11-01)
      <p>Venous thromboembolism (VTE) is a collective term for pulmonary embolism (PE) and deep vein thrombosis (DVT). Chronic Obstructive Pulmonary Disease (COPD) is described as a moderate risk factor for VTE, but the association has so far been scarcely examined. The aims of this thesis were to I) investigate the impact of COPD on the risk of incident VTE and the risk of mortality in COPD-patients with ...
    • Impact of respiratory symptoms and oxygen saturation on the risk of incident venous thromboembolism-the Tromsø study.

      Background: Chronic obstructive pulmonary disease (COPD) is associated with risk of venous thromboembolism (VTE). It remains unknown whether individual respiratory symptoms and lowered oxygen saturation (SpO<sub>2</sub>), individually and in combination with COPD, affect the risk of VTE.<p> <p> Objectives: To investigate whether measures of respiratory impairments including respiratory symptoms ...
    • Myocardial infarction as a transient risk factor for incident venous thromboembolism: Results from a population-based case-crossover study 

      Sejrup, Joakim Knutsen; Børvik, Trond; Grimnes, Gro; Isaksen, Trond; Hindberg, Kristian; Hansen, John-Bjarne; Morelli, Vania Maris; Brækkan, Sigrid Kufaas (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-16)
      Patients with myocardial infarction (MI) are at increased short-term risk of venous thromboembolism (VTE). The mechanisms behind this association are unclear. We aimed to investigate the impact of acute MI as a transient risk factor for incident VTE while taking other concomitant VTE risk factors into account. We conducted a case–crossover study of VTE patients (<i>n</i> = 707) recruited from the ...
