Chronic lung disease (CLD), such as asthma, chronic obstructive pulmonary disease (COPD), and restrictive lung diseases, has been reported to be a moderate risk factor for the development of venous thromboembolism (VTE) [1]. In addition, CLD could have a significant impact on acute mortality, and CLD is included in the simplified Pulmonary Embolism Severity Index (sPESI), which is a prognostic score for short-term mortality [2–5]. However, there is still limited data on the impact of CLD on long-term clinical outcomes in patients with VTE.
