[Effect of transcutaneous electric acupoints stimulation on vascular endothelial function and inflammatory factors after percutaneous coronary intervention]

To observe the effect of transcutaneous electric acupoints stimulation (TEAS) on vascular endothelial function and inflammatory factors after percutaneous coronary intervention (PCI) in patients.A total of 94 patients with coronary heart disease and undergoing PCI were randomized into a TEAS group and a sham-TEAS group, 47 cases in each one. In the TEAS group, TEAS started at unilateral Neiguan (PC6) and Ximen (PC4) 30 min before PCI till the end of PCI. In the sham-TEAS group, the procedure and persistent time were same as the TEAS group, but no electric stimulation was performed. Before treatment and at 8 h and 24 h after PCI, the levels of serum endothelin-1 (ET-1), von Willebrand factor (vWF), nitric oxide (NO), blood flow dependent diastolic function (FMD), interleukin-6 (IL-6), inteleukin-10 (IL-10), matrix metalloproteinase-9 (MMP-9) and high-sensitivity C-reactive protein (hs-CRP) were detected in the patients successively.Compared with the levels before PCI, the levels of ET-1 and vWF were all increased at 8 h and 24 h after PCI in the two groups (TEAS effectively improves the vascular endothelial function and reduces serum inflammatory factors after PCI.
