Abstract:
Objective To study the changes and clinical significance of glutathione redox-state in patients with coronary heart disease (CHD). Methods Based on both with or without atherogenic risk factors and the result of coronary arteriography, 118 patients were calssified into three groups: control group( n =30) ,risk group(n =28) and CHD group (n =60). Venous blood sample was obtained, then the plasma reduced glutathione ( GSH) and oxidized glutathione (GSSC) were measured by using glutathione reductase recycling method. Redox potential(EhCSH/GSSG) was calculated using Nernst equation. According to clinical situation,CHD group was divided into two subgroups:un-stable angina pectoris( UAP) group(n = 32) and acute myocardial infarction (AMI) group (n =28). Results From control group to risk group,then to CHD group,GSH gradually decreased,and there was significant difference between CHD group and control group (P < 0.05 ) , but GSSG and EhGSH/GSSG gradually increased, there was significant difference between CHD group and risk group and control group (P < 0. 05). There was no significant difference be-tween the UAP subgroup and AMI subgroup in GSH,GSSG and EhGSH/GSSG(P >0.05). Conclusions Body's an-tioxidant capacity decreases and the oxidative stress exists in artherosclerosis, and furthermore there is a certain degree of relevance between oxidative stress and hyperlipoidemia,all these show that improving this situation may decelerate or prevent the formation and progress of artherosclerosis.
