RESUMO
Objective To study the correlation between coronary lesion and Cystatin C (CyC),Nitric Oxide (NO)and Super oxide dismutase,accumulate the clinical experience in prevention and diagnose of Coronary Heart Disease (CHD)by analy-zing the contents of serum Cystatin C (CyC),Nitric Oxide and Superoxide Dismutase in patients with coronary lesion.Meth-ods According to their severity of coronary artery lesion,all cases were divided into four groups:Normal compared group (40 cases);Simple branch pathological group (44 cases);Double branch pathological group (43 cases):Multi-branch patho-logical group (35 cases).All cases were tested CyC,NO,SOD and hs-CRP in serum.Results The level of CyC and hs-CRP were increased gradually from normal group to multi-branch group.The level of NO and SOD were decreased gradually from normal group to multi-branch group.There were significant differences the levels of CyC,NO,SOD and hs-CRP among the four groups.Coronary lesion Gensini in the CHD patients had significant positive relationship to the level of CyC or hs-CRP respectively (r=0.473,0.429),had significant negative relationship to the level of NO or SOD respectively (r=-0.356, 0.384)(P<0.05).CyC in the CHD patients had significant positive relationship to the level of hs-CRP (r=0.458),had sig-nificant negative relationship to the level of NO or SOD respectively (r=-0.426,0.484,P<0.05).Conclusion By aggra-vation of coronary artery lesion,the level of CyC increased,reduced the contents of NO,SOD,aroused endothelial dysfunc-tion,induced occurrence and aggravation of coronary artery lesion.CyC,NO and SOD play important mark in the assistant diagnosis of the disease.
RESUMO
Objective To study the correlation between chronic infection of three microorganism and coronary artery lesion by detecting their antibodies and high-sensitivity C-reactive protein(hs-CRP) .Methods According to their severity of coronary artery lesion ,patients enrolled in the study were divided into 4 groups ,including normal control group(n=37) ,single-branch lesion group (n=36) ,double-branch lesion group(n= 30) and multi-branch lesion group(n= 29) .Serum Chlamydia pneumonia IgG(CPN-IgG) ,Helicobacter pylori IgG(HP-IgG) ,human cytomegalo virus IgG (HCMV-IgG) and hs-CRP tests were performed .Results CPN-IgG ,HP-IgG ,HCMV-IgG positive rates and the mixed infection positive rates increased sequentially from normal group to multi-branch group .There were significant differences of CPN-IgG ,HP-IgG ,HCMV-IgG and hs-CRP contents among the 4 groups (P<0 .05) .Logistic analysis showed that CPN-IgG ,HP-IgG and HCMV-IgG were dangerous factors to coronary artery lesion . Conclusion Chronic infections of three microorganism might affect the development of coronary artery lesion .
