Key result
COPD is linked to increased PE risk but not post-anticoagulation VTE recurrence.
Why the study?
The paradoxical association between COPD and venous thromboembolism, particularly pulmonary embolism, presents a clinical dilemma due to overlapping symptoms and differing risk profiles.
Highlights the clinical dilemma and paradoxical association where COPD increases the initial risk of pulmonary embolism but not the risk of recurrence after stopping anticoagulation.

Supports individualized anticoagulation duration decisions in COPD with VTE; leaves open drivers of initial PE risk for prospective study.
Chronic obstructive pulmonary disease (COPD) is recognised as a moderate risk factor (odds ratio between 2 and 9) for venous thromboembolism (VTE) [1], in the same group as cancer or oral contraceptive therapy. However, as opposed to cancer or the pill, this statistical association may represent a clinical dilemma [2], as COPD and the thoracic clinical presentation of VTE (pulmonary embolism, PE) have similar symptoms. The comprehension of the paradoxical association of COPD and VTE, particularly PE, has improved significantly in recent years [3–8]. COPD is associated with an increased risk of PE, but not of VTE recurrence after anticoagulant therapy cessation

Laurent Bertoletti (2017) conducted a review in Chronic obstructive pulmonary disease (COPD) and pulmonary embolism. Chronic obstructive pulmonary disease (COPD) was evaluated on Venous thromboembolism (VTE) and pulmonary embolism (PE). COPD is associated with an increased risk of pulmonary embolism, but not of venous thromboembolism recurrence after anticoagulant therapy cessation.
