This randomized controlled trial evaluated the effects of intraoperative electroacupuncture (EA) on angina and periprocedural myocardial injury in 120 patients undergoing percutaneous coronary intervention (PCI). The EA group reported significantly lower intraoperative angina scores (P < 0.001) and had lower hs-cTnT levels at 24 hours post-PCI compared to the sham group (median [IQR]: 25.27 [11.54, 108.65] vs. 35.37 [14.35, 237.25]; P = 0.042).
Key findings
- EA group had significantly lower intraoperative angina scores compared to sham (P < 0.001).
- hs-cTnT levels were significantly lower in the EA group at 24 hours post-PCI (P = 0.042).
- Concentrations of TNF-α and IL-6 were significantly lower in the EA group (P < 0.05 for both).
- No significant difference in adverse event incidence between EA and sham groups (P > 0.05).
Why it matters
The findings suggest that intraoperative electroacupuncture may provide effective pain relief and reduce myocardial injury during PCI, potentially improving patient outcomes. Understanding these benefits can help clinicians consider adjunctive therapies in procedural settings.
