To explore the effects of allitridi capsules on endothelial function and clinical prognosis after percutaneous coronary intervention (PCI) in coronary artery disease (CAD) patients with diabetes mellitus (DM). A total of 120 CAD patients with DM undergoing PCI were randomly assigned to receive conventional (control, n = 60) and additional allitridi treatment (120 mg/day, n = 60) for 3 months.Serum nitric oxide (NO) and intercellular adhesion molecule 1 (ICAM-1) levels were determined by enzyme-linked immunosorbent assay (ELISA) immediately and at 3 months post-PCI. Endothelial function was assessed by endothelium dependent flow-mediated dilation (FMD). Duration of follow-up was 1 year after PCI. The clinical characteristics, serum NO and ICAM-1 levels and FMD at baseline were not different between two groups. At Month 3 post-PCI, serum NO level was markedly higher ((147 ± 32) vs (112 ± 24) µmol/L, P = 0.009) and serum ICAM-1 level was significantly lower ((182 ± 21) vs (232 ± 29) µmol/L, P = 0.021) in the allitridi group than in the control group.Furthermore, treatment of allitridi resulted in a significant improvement of FMD (8.2% ± 2.4% vs 6.4% ± 2.3%, P = 0.013). At Year 1 post-PCI, the incidence of major adverse cardiovascular event (MACE) was lower in the allitridi group than that in the control group (10.5% vs 17.2%, P = 0.022). Allitridi capsules significantly improve the clinical prognosis after PCI in CAD patients with DM. Its mechanism may lies in improved endothelial function and vascular inflammatory state.
