Efficacy and Safety of Ultrasound Modulation of Stellate Ganglion for the Prevention of Ventricular Arrhythmia in Patients With ST-segment Elevation Myocardial Infarction

China100 participantsStarted 2026-05-05

Plain-language summary

The goal of this multicenter, double-blind, randomized controlled trial is to evaluate the efficacy and safety of low-intensity focused ultrasound (LIFU) stellate ganglion modulation for preventing ventricular arrhythmias after ST-segment elevation myocardial infarction (STEMI) in patients undergoing percutaneous coronary intervention (PCI). The main questions it aims to answer are: 1. Does LIFU reduce the frequency and duration of ventricular arrhythmias within 72 hours post-PCI compared to sham ultrasound? 2. Does LIFU improve electrophysiological stability, myocardial injury markers, cardiac function and heart rate variability, and reduce inflammatory markers and sympathetic neurotransmitters? 3. What is the safety profile of LIFU in this population? 100 eligible patients will be randomized 1:1 to receive either active LIFU (2.0W, 1MHz, 50% duty cycle, 30min per session: 1 intra-PCI session + 7 daily post-PCI sessions) plus standard care, or identical sham ultrasound plus standard care. A comprehensive double-blind design (subjects, operators, assessors, statisticians) will be implemented. The study will run from May 2026 to April 2027 at 7 centers in China, led by Renmin Hospital of Wuhan University. Participants will: 1. Complete pre-PCI screening and baseline assessments (informed consent, demographic/medical history, physical examination, electrocardiogram, echocardiogram, blood sample collection) within 12 hours of symptom onset 2. Receive 1 assigned ultrasound intervention during PCI, followed by 1 daily intervention for 7 consecutive days postoperatively 3. Undergo 72h continuous ECG monitoring post-PCI, blood sampling at baseline and postoperative days 1, 3, 7, and echocardiography assessment at postoperative day 7 4. Have all adverse events and arrhythmias recorded throughout the study 5. May withdraw voluntarily at any time without affecting routine medical care

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.
