Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include patients with suspected CTEPH who exhibit symptoms and have undergone relevant imaging studies.
✕Probably not a fit
Patients with a normal perfusion lung scan or those under legal guardianship may not benefit from this study.

What this trial studies
This observational study aims to identify a specific proteomic pattern in patients suspected of having Chronic Thromboembolic Pulmonary Hypertension (CTEPH). Patients with symptoms such as persistent dyspnea and perfusion defects will undergo blood sampling to analyze their proteomic profiles. The study seeks to improve diagnostic accuracy for CTEPH, which is often misdiagnosed due to limitations in current imaging techniques like transthoracic echocardiography. By establishing a reliable proteomic signature, the study hopes to enhance patient evaluation and management.
Why it matters
Potential benefit: If successful, this study could lead to more accurate and timely diagnoses of CTEPH, improving patient outcomes.
How similar studies have gone: While the approach of using proteomic patterns for diagnosis is innovative, similar studies have shown promise in other conditions, suggesting potential for success.
