Digital Assessment of Real-World Walking Activity in Pulmonary Hypertension: A Prospective Multicenter Trial

This study is using a small wearable sensor to track how much people with pulmonary hypertension (high blood pressure in the lungs) actually walk in their daily lives outside of a clinical setting. Researchers want to see if real-world activity levels provide useful information about disease progression. **You may be eligible if...** - You have been diagnosed with pulmonary hypertension confirmed by a heart catheterization procedure - You can walk independently (without assistance) and can walk more than 100 meters in 6 minutes - Your disease is classified as WHO Functional Class I, II, or III (mild to moderate symptoms) - You are willing to wear a small movement sensor on your ankle for 7 days - You have a follow-up visit scheduled in 3, 6, or 12 months **You may NOT be eligible if...** - You were hospitalized for a lung condition in the 30 days before joining the study - You cannot walk independently or your 6-minute walking distance is under 100 meters - You are unwilling or unable to wear the activity sensor Talk to your doctor to see if this trial is right for you.
