Task: Answer Verification
Input (English): Question: Does pulmonary vascular resistance predict early mortality in patients with diffuse fibrotic lung disease and suspected pulmonary hypertension?
Answer: In severe DLD, early mortality is strongly linked to increased PVR but not to other RHC or non-invasive variables. These findings suggest that the threshold for RHC in severe DLD should be low, enabling prioritisation of aggressive treatment including lung transplantation.
Output (English): yes
