Summary

This study looks at whether environmental toxins, drugs, and workplace exposures play a role in causing pulmonary arterial hypertension (PAH), a rare and serious lung condition. Researchers will compare 150 newly diagnosed patients with PAH to those with another form of pulmonary hypertension (CTEPH) by testing their hair and urine for 180 toxins. The goal is to identify potential triggers that may help explain why some people develop PAH.
