Abstract:
Objective To investigate the relationship between serum homocysteine (HCY)levels and oxidative stress in pa-tients with coronary heart disease (CHD).Methods According to the diagnostic criteria of CHD in 2010 (WS 319-2010)is-sued by the Ministry of Health,79 patients with CHD in Xi’an Central Hospital from June 2014 to December 2014 were se-lected as the experimental group,and 5 5 cases of healthy physical examination for the same period were selected as the nor-mal control group.The levels of oxidative stress marker malondialdehyde (MDA)and the activity of antioxidant enzyme su-peroxide dismutase (SOD)in serum were detected to analyze the state of oxidative stress.The levels of serum HCY were de-tected,and the correlation between HCY levels and MDA levels and SOD activity was analyzed.Results The levels of MDA in the CHD group were significantly higher than that in the control group,while SOD activity was significantly lower than that in the control group,the differences were statistically significant (t=3.112,2.684,all P<0.05).The levels of HCY in the CHD group were significantly higher than that in the control group,the difference was statistically significant (t=3.268,P<0.05).In the CHD group,the levels of HCY were positively correlated with the levels of MDA (r=0.236,P<0.05),and negatively correlated with SOD activity (r=-0.221,P<0.05).Conclusion Serum HCY levels were increased and oxidative stress reaction was enhanced in patients with CHD.Oxidative stress was associated with elevated serum HCY levels.Serum HCY levels and oxidative stress played an important role in the occurrence and development of CHD.
