What to expect
No one can promise a trial will help you personally — that is what the research is trying to find out.
What participation involves
- Time periods mentioned: 4 weeks
- Procedures mentioned: Blood draws, Questionnaires, Heart tracing (ECG)

- "The study will be conducted over 4 weeks and patients will undergo low-level tragus stimulation for 1 hour every day for 4 weeks."
- "At baseline the following tests will be conducted-6-minute walk distance, vascular function testing using noninvasive device and blood samples will be collected."
- "A 6MWD and QoL (using Pulmonary hypertension questionnaire) will be performed at baseline and follow up (1 months)."
- "EKG for heart rate variability, Six minute walk test, Endopat test for endothelial dysfunction would re recorded."
- "Patients will maintain a diary log for 4 weeks and perform stimulation for 1 hour daily (typically between 4-8pm, during the 2nd diurnal phase of high sympathetic tone)."
- Compensation
- Not stated
- Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
- Participants are monitored closely by the research team throughout the study.
- Some participants may receive access to an investigational treatment, which is still being studied.
- Your participation helps researchers learn whether this approach could help future patients.
About this study
In plain language
This study tests whether gentle stimulation of the tragus, a small flap on the outer ear, can improve blood vessel health, walking distance, and blood test results. It is for adults with Group 1 pulmonary arterial hypertension, or high blood pressure in the lungs. Participants will use the stimulation for 1 hour each day for 4 weeks, with tests before and after.
Patients with Group 1 pulmonary hypertension will be enrolled in this study. Investigators will test the hypothesis of low-level tragal stimulation in patients with pulmonary hypertension. The study will be conducted over 4 weeks and patients will undergo low-level tragus stimulation for 1 hour every day for 4 weeks. At baseline the following tests will be conducted-6-minute walk distance, vascular function testing using noninvasive device and blood samples will be collected. Patient will also undergo a limited echocardiography to assess right ventricular function. After 4 weeks of stimulation patients will come back to undergo these tests again. Investigators hypothesized that low-level tragus stimulation (neuromodulation) will lead to improvement in vascular function, 6-minute walk distance and blood based biomarkers in patients with pulmonary hypertension.
Compensation is read from the study's own description and may be missing — always confirm with the study team.
