Abstract
- Electroacupuncture pretreatment (EAP) safely protects the heart from ischemic injury, however, the efficacy of EAP for periprocedural myocardial injury after percutaneous coronary intervention (PCI) remains unclear. Our aim was to investigate whether EAP prior to PCI reduces post-PCI myocardial injury in patients with coronary artery disease (CAD). 388 patients (≥ 18 years old) with CAD, undergoing elective PCI were enrolled and randomized, out of those 204 went through the whole trial. EAP was conducted by 30-minute electrical stimulation through 4 electrodes attached to the Antiguan (PC6) and Ximen (PC4) acupoints in the forearm bilaterally 1-2h prior to PCI. The control group had sham electrodes but no electrical stimulation. The primary end point was the incidence of myocardial infarction type 4a (MI4a) based on serum cTnI values at 24h after PCI. The secondary end points included post-procedural cardiac function and the major adverse cardiac/cerebrovascular event (MACCE) rate. EAP prior to PCI significantly reduced the incidence of MI4a (serum cTnI≥0.20 ng/mL) 24h post-PCI compared to the control group (P=0.004). The echocardiography at 6 months after PCI revealed significant improvement in cardiac function in the EAP group compared with the control group. The MACCE rate was significantly decreased in the EAP group at 24 month follow-up compared to the control group (P=0.0157). Moreover, multivariate logistic regression analysis showed that EAP was associated with decreased likelihood of MACCE (odds ratio 0.327, 95% CI 0.140-0.767, P=0.010). EAP prior to PCI significantly reduced cTnI release and protected patients with CAD from subsequent myocardial injury after PCI procedure.<br /> (Copyright © 2015 Elsevier Ireland Ltd.
