About this study

The study recruited consecutive outpatients or hospitalized patients diagnosed with pulmonary embolism (PE cohort) and chronic thromboembolic pulmonary hypertension (CTEPH cohort). The follow-up of all patients was performed annually by phone or outpatient visit. The main outcomes were bleeding, recurrent events, and survival. The objective of the study was to explore the pathogenesis, therapy and outcome of PE and CTEPH.

Treatment and study plan

Primary outcomes

  1. Recurrent Incidence of Patients

    Time frame: through study completion, an average of 1 year.

    Recurrent PE was measured by computed tomography pulmonary angiography (CTPA) or ventilation/perfusion (V/Q) lung scans. Recurrent deep venous thrombosis was measured by lower extremity Doppler ultrasound.

  2. Bleeding Rate of Patients

    Time frame: through study completion, an average of 1 year.

    Events were recored by follow-up.

  3. Survival Rate of Patients

    Time frame: through study completion, an average of 1 year.

    Events were recored by follow-up.
