Identifying a proteomic pattern for diagnosing chronic thromboembolic pulmonary hypertension

Proteomic Pattern Associated With the Diagnosis of Chronic Thromboembolic Pulmonary Hypertension : PROTEO-CTEPH Study.

Observational Centre Hospitalier Universitaire de Saint Etienne · NCT05340023

This study is trying to find a specific pattern in blood proteins to help doctors better diagnose chronic thromboembolic pulmonary hypertension in patients who have symptoms like shortness of breath.

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.

Who should consider this trial

Good fit: Ideal candidates include patients with suspected CTEPH who exhibit symptoms and have undergone relevant imaging studies.

Not a fit: Patients with a normal perfusion lung scan or those under legal guardianship may not benefit from this study.

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 performed: While the approach of using proteomic patterns for diagnosis is innovative, similar studies have shown promise in other conditions, suggesting potential for success.
