The study is to investigate hyperbaric oxygen therapy (HBOT) on myocardial perfusion of patients after the implantation of drug-eluting stents (DES) METHODS: From December 2013 to December 2015, a total of 115 patients with CAD who received DES implantation were included in this retrospective study. They were divided into HBOT group (n=55) and control group (n=60) according to different treatments retrospectively. Gated myocardial perfusion single photon emission computed tomography (SPECT) was conducted in all the patients. Endothelin-1 (ET-1), high sensitivity C reactive protein (hs-CRP) and nitric oxide (NO) were detected by the corresponding assay kits. After HBOT treatment in HBOT group, SPECT results showed that the improvement rate of impaired sub-segments in patients of HBOT was significantly higher than that in control group (<0.05), and the parameters of PFR, TPFR, MFR/3 were displayed with marked differences between the two groups (<0.05). The laboratory results demonstrated a statistically increased level of NO and decreased levels of ET-1 and hs-CRP between the two groups (<0.05). HBO may improve myocardial blood perfusion, reduce inflammation and vascular endothelial dysfunction, and further improve myocardial microcirculation in patients after the implantation of drug-eluting stents.
