Developing the Probability Algorithm for Pulmonary Hypertension Echocardiography

This study is building a better tool to diagnose pulmonary hypertension — a condition where blood pressure in the lungs is too high — using heart ultrasound scans. Researchers are analyzing existing patient test data to improve how accurately ultrasound can detect this condition. **You may be eligible if...** - You are 18 or older - You have had a heart ultrasound (echocardiogram), an ECG, and a right heart catheterization as part of your regular care **You may NOT be eligible if...** - You are under 18 - You have a known or suspected heart defect present from birth - You have opted out of allowing your health data to be used for research in England or Scotland Talk to your doctor to see if this trial is right for you.
