endothelin-1 and diallyl-trisulfide

To explore the effects of allitridi capsules on endothelial function and clinical prognosis in coronary artery disease (CAD) patients with obstructive sleep apnea hypopnea syndrome (OSAHS).. A total of 80 CAD patients with OSAHS were randomly assigned to receive conventional treatment (control, n = 40) and additional allitridi treatment (120 mg/day, n = 40) for 6 months. Another 40 CAD patients without OSAHS and 30 healthy individuals were chosen as controls. Endothelial function was assessed by endothelium dependent flow-mediated dilation (FMD) with high-definition color Doppler ultrasound. Serum nitric oxide (NO) and plasma endothelin-1 (ET-1) levels were determined by enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay. The duration of follow-up was 1 year.. The baseline clinical characteristics were not different between control and allitridi groups (P > 0.05). Compared with CAD patients without OSAHS, FMD and serum NO level were significantly lower ((7.9 ± 1.5)% vs (11.2 ± 2.9)%, P = 0.011 and (71.11 ± 10.62) vs (86.28 ± 11.03) µmol/L, P = 0.007), plasma ET-1 level was markedly higher ((112.34 ± 17.22) vs (89.87 ± 11.56) ng/L, P = 0.025) in CAD patients with OSAHS. At Month 6 post-treatment, FMD and serum NO level were significantly higher ((12.1 ± 3.1)% vs (9.1 ± 1.6)%, P = 0.020 and (105.24 ± 17.01) vs (82.39 ± 11.12) µmol/L, P = 0.001) and plasma ET-1 level in the allitridi group was lower ((77.12 ± 9.65) vs (97.77 ± 11.04) ng/L, P = 0.001) than that in the control group. At Month 12 post-treatment, the incidence of MACE was lower in the allitridi group than that in the control group (8.3% vs 15.8%, P = 0.016).. Allitridi capsules significantly improved endothelial function in CAD patients with OSAHS.
