Analysis on the correlation between ADMA concentration and acute coronary syndrome′s risk factors / 国际检验医学杂志

ABSTRACT

Objective To study the asymmetric dimethylarginine(ADMA) concentrations in plasma of acute coronary syndrome (ACS) and its various subgroups ,and analyze the relationship between ADMA and traditional risk factors of ACS .Methods 101 ACS patients were enrolled in the study ,which were divided into several subgroups according to clinical diagnosis ,ECG and coro‐nary angiography .ACS group were divided into unstable angina(UA) group(n=70) and acute myocardial infarction(AMI) group (n=31) ,then AMI group was divided into non‐ST segment elevation myocardial infarction(NSTEMI) group(n=19) and ST seg‐ment elevation myocardial infarction (STEMI) group(n=12) .The control group(n= 40) were recruited in the study during the same period ,who showed normal coronary arteries in coronary angiography .All the patients received coronary attery angiography . The plasma ADMA concentration was measured by using enzyme‐linked immunosorbent assay (ELISA) ,and serum contents of lip‐id(TC ,TG ,HDL‐C ,LDL‐C) ,C‐reactive protein(CRP) ,troponin were detected by automatic biochemic analysis apparatus .Results Compared with the control group ,plasma ADMA concentration of ACS group increased ,the difference was statistically significant (P<0 .05) .The concentrations of ADMA in AMI group and UA group were higher than those in control group ,and the difference was statistically significant(P< 0 .05) .The concentrations of ADMA in AMI group were significantly higher than those in UA group(P<0 .05) .Plasma ADMA negatively correlated with HDL‐C concentrations(r= -0 .222 ,P<0 .05) ,positively correlated with LDL‐C concentration(r=0 .357 ,P<0 .05) ,and positively correlated with CRP(r=0 .619 ,P<0 .05) .Conclusion The occur‐rence of ACS and some of its related risk factors are correlated with plasma ADMA concentration .
