What is the Role of the Exposome in Pulmonary Hypertension

Brief summary (registry, in English)

Pulmonary arterial hypertension (PAH) is a rare and incurable disease affecting people of all ages. It is characterized by obstructive remodeling of the small pulmonary arteries, responsible for an increase in pulmonary arterial pressure, leading to right heart failure and death in the absence of treatment. PAH can be associated with a variety of diseases, but around half of all PAH cases are idiopathic or hereditary, and may develop on predisposed terrain following a "second hit", as suggested by the identification of PAH cases associated with the use of anorectic drugs, methamphetamine and occupational exposure to organic solvents. No study has systematically analyzed the exposome of patients with PAH, combining environmental and occupational exposures as well as drugs and medications. The exposome of patients with PAH without associated causes will be compared with that of patients with another form of pulmonary hypertension (PH), linked to thromboembolic risk factors: chronic thromboembolic PH (CTEPH), which will constitute the control group.
