Trial summary

The diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) is difficult for numerous reasons and is related with a poor prognosis. In Taiwan, the incidence of CTEPH and its clinical features are unknown. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 20 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Patients with contrast CT image and cardiac echo data and confirmed/suspected as CTEPH can be included in the screening (initial registration). Those who have confirmed diagnosis of CTEPH in expert centers (IRB approved for patient enrollment) will be enrolled into the study.

Who may be able to join

  • Right heart catheterization (RHC) results that are in line with both of the following haemodynamic levels:
  • Mean pulmonary arterial pressure (mPAP) ≥ 25 mmHg at rest AND Pulmonary arterial wedge pressure (PAWP) ≤ 15 mmHg
  • Confirmation of CTEPH diagnosis by one of the following as recommended by standard guidelines:
  • At least 1 (segmental) perfusion defect(s) in ventilation-perfusion (V/Q) / perfusion scan OR Pulmonary artery obstruction seen by multidetector computed tomography (MDCT) angiography or conventional pulmonary cineangiography.
  • Presence of pulmonary hypertension or evidence of pulmonary thromboembolism after at least 3 months of anticoagulation treatment.

Who cannot join

  • not written informed consent
  • not meet inclusion criteria

About this study

The diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) is difficult for numerous reasons and is related with a poor prognosis. In Taiwan, the incidence of CTEPH and its clinical features are unknown. This study aims at evaluating the prevalence, clinical characteristics, and management of CTEPH in a Taiwanese cohort.

Primary objective:

  • To investigate the geodemographics of CTEPH in Taiwan

Secondary objectives:

  • To characterize the demographics and clinical presentation of patients with CTEPH
  • To describe the real-world management and treatment outcome of patients with CTEPH
  • To identify the risk factors of CTEPH
  • To assess the relationship between risk factors/patients' characteristics and clinical outcomes for CTEPH
  • To evaluate the prognosis of CTEPH in Taiwan using survival assessment

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To investigate the geodemographics of CTEPH in Taiwan

    variables of interest also include (1) patients characteristics, such as demographics and medical history; (2) clinical features and diagnosis records, such as risk factors, comorbidities, CTEPH diagnosis data, concomitant conditions; (3) management of CTEPH, including surgery and medication; and (4) clinical outcome including clinical assessment results, survival status, and clinical worsening related to CTEPH.

    Measured: recruiting period two years
