Objective:To explore the effect of digoxin and Tongxin capsule combined therapy on oxidative stress, cytokines and vascular endothelial function in patients with chronic heart failure, and provide help for clinical treatment of patients with chronic heart failure.Methods:95 cases of chronic heart failure in our hospital were randomly divided into observation group (47 cases) and control group (48 cases). Control group patients were given basic treatment, and observation group received combination therapy of digoxin and Tongxinluo capsule, to detect and to investigate the changes of oxidative stress, cytokines and vascular endothelial function in two groups of patients before and after treatment.Results:There was no significant difference in oxidative stress, cytokines and vascular endothelial function between the two groups of chronic heart failure patients before treatment (P>0.05). Compared with before treatment, the malondialdehyde (MDA) and cytokines [tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), interleukin-6 (IL-6) and brain natriuretic peptide (BNP)] in two groups of patients with chronic heart failure after treatment decreased significantly (P<0.05), while indexes related to endothelial function [hyperemic brachial artery diameter after reactive hyperemia, brachial artery diameter change rate, brachial artery endothelial dependent diastolic function (FMD), and brachial artery endothelium dependent diastolic function (NMD)] and related indexes of oxidative stress [glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), and catalase (CAT)] were significantly increased (P<0.05). The related indexes and oxidative stress indexes (GSH-Px, CAT and SOD) of observation group after the combined treatment in patients with endothelial function were significantly higher than the control group after treatment (P<0.05). After treatment, cytokines and MDA levels were significantly lower than the control group (P<0.05).Conclusions:Tongxinluo capsule combined with digoxin treatment significantly improved the oxidative stress, cytokines and vascular endothelial function levels in patients with chronic heart failure, and has important clinical significance for the treatment of patients with chronic heart failure.
