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. 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
