In the PIOPED study, the 1-year mortality rate was 24%. [35] The deaths occurred due to cardiac disease, recurrent pulmonary embolism, infection, and cancer.

The risk of recurrent pulmonary embolism is due to the recurrence of proximal venous thrombosis; approximately 17% of patients with recurrent pulmonary embolism were found to have proximal DVT. In a small proportion of patients, pulmonary embolism does not resolve; hence, chronic thromboembolic pulmonary arterial hypertension results.
