NCT07587294

Brief 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. 1.Does LIFU reduce the frequency and duration of ventricular arrhythmias within 72 hours post-PCI compared to sham ultrasound?
  2. 2.Does LIFU improve electrophysiological stability, myocardial injury markers, cardiac function and heart rate variability, and reduce inflammatory markers and sympathetic neurotransmitters?
  3. 3.What is the safety profile of LIFU in this population?
  4. 4.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
  5. 5.Receive 1 assigned ultrasound intervention during PCI, followed by 1 daily intervention for 7 consecutive days postoperatively
  6. 6.Undergo 72h continuous ECG monitoring post-PCI, blood sampling at baseline and postoperative days 1, 3, 7, and echocardiography assessment at postoperative day 7
  7. 7.Have all adverse events and arrhythmias recorded throughout the study
  8. 8.May withdraw voluntarily at any time without affecting routine medical care

Study Arms (2)

Ultrasound stimulation group

EXPERIMENTAL

Subjects in this arm will receive low-intensity focused ultrasound (LIFU) intervention targeting the left stellate ganglion. The ultrasound probe and skin are disinfected, ultrasound coupling gel is applied, the probe is placed on the skin surface corresponding to the anatomical location of the left stellate ganglion, fixed with a robotic arm, and the instrument is activated. Ultrasound parameters: power 2.0 W, frequency 1 MHz, 50% duty cycle, 30 minutes per session. One session is performed during PCI, followed by once daily for 7 consecutive days postoperatively. All subjects will receive standard cardiovascular care in accordance with 2025 ACC/AHA guidelines, including PCI and indicated medications.

Device: Ultrasound modulation of the left stellate ganglion

Sham group

PLACEBO COMPARATOR

Subjects in this arm will receive sham ultrasound intervention targeting the left stellate ganglion. The ultrasound probe and skin are disinfected, ultrasound coupling gel is applied, the probe is placed on the skin surface corresponding to the anatomical location of the left stellate ganglion and fixed with a robotic arm. No ultrasound energy is delivered, while the instrument maintains an identical appearance and operational state to the active LIFU arm. Ultrasound parameters: power 2.0 W, frequency 1 MHz, 50% duty cycle, 30 minutes per session. One sham session is performed during PCI, followed by once daily for 7 consecutive days postoperatively. All subjects will receive standard cardiovascular care in accordance with 2025 ACC/AHA guidelines, including PCI and indicated medications.
