Low-Intensity Focused Ultrasound Targeting the Stellate Ganglion for Regulating Autonomic Nerve Function and Sleep Quality in Perioperative Patients With Cardiovascular Diseases

Starting soon · Not applicable · Has a placebo group

Conditions studied: Diagnosed With Cardiovascular Diseases and Scheduled to Undergo Interventional Cardiology Procedures

In brief

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 improving autonomic function and sleep quality in perioperative cardiovascular disease patients. The main questions it aims to answer are: 1. Does LIFU improve heart rate variability and sleep characteristics from baseline at 3-7 days post-surgery compared to sham ultrasound? 2. Does LIFU improve serological markers, vital signs, Pittsburgh Sleep Quality Index (PSQI), and reduce \>30-second perioperative arrhythmias? 3. What is the safety profile of LIFU in this population? 200 eligible patients will be randomized 1:1 to receive either active LIFU (2.0W, 1MHz, 50% duty cycle, 30min daily for 3-7 days) plus standard care, or identical sham ultrasound plus standard care. A four-party double-blind design (subjects, operators, assessors, analysts) will be implemented. The study will run from May 1, 2026 to April 1, 2027 at 6 centers in China. Participants will: 1. Complete pre-surgery screening and baseline assessments (PSQI, 12h ECG/sleep monitoring, residual blood sample collection) 2. Receive daily assigned ultrasound intervention for 3-7 consecutive days post-surgery 3. Undergo 72h continuous ECG monitoring post-surgery, and repeat assessments at 3-7 days 4. Have all adverse events and arrhythmias recorded throughout the study 5. May withdraw voluntarily at any time without affecting routine medical care
