What this trial studies

This observational study aims to assess the safety and efficacy of balloon pulmonary angioplasty (BPA) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) who are not suitable for pulmonary endarterectomy or have persistent CTEPH after the procedure. The study involves a multi-center approach, where clinical evaluations such as functional capacity tests, biomarkers, and imaging studies will be conducted before and after BPA treatment. Additionally, the study will explore the predictive value of FAPI in determining treatment efficacy and patient prognosis.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with CTEPH who are not amenable to pulmonary endarterectomy and have been on anticoagulation therapy for at least three months.

Not a fit: Patients who are unwilling or unable to provide consent or those who cannot be followed up will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with CTEPH who currently have limited therapeutic alternatives.

How similar studies have performed: While balloon pulmonary angioplasty is a recognized treatment, this specific observational study is novel in its comprehensive evaluation of safety and efficacy in the Chinese population.
