This study focuses on early detection of pulmonary hypertension (PH) in patients with interstitial lung disease (ILD), which is a group of lung disorders that cause lung scarring. **PH** is high blood pressure in the lungs. In the study, participants will have medical tests to look for signs of PH. These tests include breathing tests, CT scans, heart exams, a 6-minute walk test, and blood tests for certain heart chemicals. No medication is being tested. There are two visits: a **Screening Visit** and **Study Visit 1**. This research aims to find better ways to catch PH early in people with ILD.

• **Study Duration:** Includes 2 visits; no medication involved.
• **Eligibility:** Must have ILD and signs of PH; can't have had certain heart or lung conditions recently.
• **Compensation:** Not mentioned, check with study organizers.
