Risk factors for CTEPH include:

  • Splenectomy

  • Large PE

  • History of cancer

  • Thyroid replacement therapy

  • Blood clotting disorders: lupus anticoagulant or antiphospholipid syndrome

  • Pacemaker infection

  • Blood type that is not type O

Studies have demonstrated that CTEPH is not more prevalent in patients who received subtherapeutic initial anticoagulation; high-quality anticoagulation did not prevent the occurrence of CTEPH. Interestingly, no relationship between hereditary thrombotic risk factor abnormalities and CTEPH has been established.
