Retrospective analysis identifies pulmonary hypertension in severe hypersensitivity pneumonitis patients, suggesting high prevalence and alternative causes in mild cases.
Key Points
The study aims to assess the prevalence of pulmonary hypertension in patients with moderate to severe hypersensitivity pneumonitis.
Retrospective analysis of HP patients undergoing lung transplantation in cohort 1.
Prospective screening for PH in HP patients participating in pulmonary rehabilitation in cohort 2.
PH assessed using echocardiography and right heart catheterization.
Cohort 1: 29% of patients had high probability of PH (sPAP > 50 mmHg).
Cohort 2: 1% of patients had high probability of PH; RHC confirmed PH in 5 patients (5% of total cohort).
PH in severe HP patients was common, but uncommon in mild HP patients, necessitating consideration of alternative causes.
