Background:High-sensitivity C-reactive protein(hs-CRP)is a major factor for predicting acute coronary syndrome(ACS).Myeloperoxidase(MPO)also plays an important role in atherosclerosis initiation and development.In the present work,a detail comparison between MPO and hs-CRP for early warning ACS is discussed.Objective:To compare the values between MPO and hs-CRP for early warning ACS and predicting major adverse cardiovascular events(MACEs)in CHD patients.Methods:MPO,hs-CRP and ACS-related risk factors from 201 ACS and 210 non-ACS patients were tested,and data were analyzed with SPSS software.Major adverse cardiovascular events(MACEs)were investigated during the 4-year period follow-up in 285 coronary heart disease(CHD)patients.Results:The areas under receiver operating characteristic(ROC)curve for diagnosing ACS were 0.888(95%CI 0.843-0.933)for MPO,and 0.862(95%CI 0.815-0.910)for hs-CRP,respectively.Compared to hs-CRP,MPO had more correlations strongly with ACS-related risk factors of TG,HDL-C and LDL-C in ACS patients(p<0.05).Prospective study demonstrated that the incidences of MACEs associated significantly with elevated MPO baseline level(yes vs no,OR 7.383,95%CI 4.095-13.309)and high hs-CRP baseline level(yes vs no,OR 4.186,95%CI 2.469-7.097).Conclusions:MPO as inflammatory marker for early warning ACS has some advantages compared to hsCRP.Elevated baseline MPO and hs-CRP levels are both valuable predictors of MACEs in CHD patients.
