Level and Correlationship of Serum SOD and hsCRP and Other Indicators in Acute Coronary Syndrome / 现代检验医学杂志

ABSTRACT

Objective To investigate the level of serum superoxide dismutase(SOD),high-sensitive C-reactive protein (hsCRP)and myocardial injury markers in acute coronary syndrome(ACS)and evaluate their relationship and diagnostic values.Methods Case control study was conducted.This study enrolled 64 ACS patients and 50 non-ACS patients from the 181st Hospital of Chinese PLA in 2015.Serum SOD,hsCRP were tested and myocardial injury markers such as cardiac tro-ponin I(cTnI),creatin kinase MB(CK-MB)were also tested.Student t test and Pearson test were used as statistical meth-ods.Results Compared with control group,SOD of ACS group were significant lower(t=4.136,P<0.001)and hsCRP, Mb,cTnI,CK and CK-MB were significant higher(t=-5.396,-3.495,-5.578,-4.655 and -4.614,all P<0.001). The area under ROC curve of SOD,hsCRP,MYO,cTnI,CK and CK-MB was 0.713,0.758,0.699,0.879,0.841 and 0.802 respectively.After pearman test,the serum SOD were correlated to hsCRP,total cholesterol(TC)and low density lipopro-tein(LDL-C)(r=-0.493,0.548 and 0.404,all P<0.01).Serum hsCRP was correlated to cTnI,triglyceride(TG)and SOD(r=0.671,-0.417 and -0.493,all P<0.01).Conclusion cTnI was positively correlated to hsCRP and markers of myocardial injury.hsCRP was negatively correlated with SOD.It implicated that oxidative stress,inflammatory response and serum lipid deposition may act an important role in the occurrence and development of ACS.
