Pulmonary Hypertension Trial, Recruiting
Who may be able to join
AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI
Who might be able to join this trial:
- People aged 18 years or older.
- People who have been diagnosed with pulmonary hypertension confirmed by a right heart catheterisation procedure, showing specific pressure and resistance measurements above set thresholds.
- People who are able to complete a six-minute walk test (a test where a person walks as far as they can in six minutes).
- People who are able to give written consent to take part.
Who may not be able to join:
- People who have peripheral arterial disease (a condition affecting blood flow in the arteries of the limbs).
- People who have tattoos or skin markings covering the back of the wrist.
- People whose resting blood oxygen level is below 88%.
- People with a serious ongoing medical condition that would prevent them from taking part in the study procedures, or whose life expectancy is less than 3 months.
- People who have a bleeding disorder.
- People who are currently taking blood-thinning medication (anticoagulants) — though there may be an exception for people taking these medications only because it was historically thought to improve long-term survival in pulmonary arterial hypertension. In that specific situation, the trial site may offer the option of pausing the medication for one week before the study visit and restarting it the following day, provided no bleeding complications occur (confirm with trial site).
