Clinical Outcome of Electrical Transcutaneous Auricular Vagal Stimulation in Patients With Stable Symptomatic Chronic Heart Failure

Austria13 participantsStarted 2014-01-01

Plain-language summary

This study aims to investigate whether electrical vagus nerve stimulation in the auricle has an impact on the clinical presentation of heart failure. The device used, P-STIM, is already successfully applied in pain therapy and angiology (peripheral arterial disease, PAD) and will also be tested against a placebo in this study. In preliminary studies, acupuncture was shown to improve the 6-minute walking distance in heart failure patients (Kristen et al., 2010). The investigators assume that acupuncture and P-STIM have similar effects, and this study also aims to improve the 6-minute walking distance as its primary endpoint. Additional endpoints include LVEF (left ventricular ejection fraction), NYHA classification, inflammatory markers (e.g., CRP, pro-BNP), and patients' quality of life. Study Design: Patients will be randomly assigned to either the placebo or the verum group. They will receive treatment for five weeks (with the device being replaced weekly) and undergo a follow-up examination after four weeks. At the beginning and during follow-up, Left ventricular ejection fraction (measured by cardiac ultrasound), inflammatory markers in the blood, NYHA classification, and quality of life (assessed by questionnaire) will be recorded. The primary endpoint, the 6-minute walking distance, will be measured at baseline, two weeks after the start of treatment, and at the follow-up examination.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
