Summary

This is a monocentric, case-control, comparative study aiming at investigating the transition from physiological to pathological pulmonary circulation in patients with pulmonary hypertension (PH) and chronic lung diseases. The study will include 105 adults participants undergoing lung surgery, divided into three groups, Group A (patients with chronic lung disease and PH undergoing lung transplantation), Group B (patients with chronic lung disease without PH), and Group C (patients without chronic lung disease nor PH). The primary objective is to identify the association between vascular remodeling and PH by measuring the medial thickness of pulmonary arteries. Secondary objectives include multimodal phenotyping (clinical, radiological, tissue, and biological) to explore mechanisms of PH development. Blood, broncho-alveolar lavage, and lung tissue samples will be collected during routine care. The study aims to improve understanding of PH pathophysiology and identify potential biomarkers and therapeutic targets.
