Objective To investigate the diagnostic value of hypersensitive troponin I (hs-cTnI) , homocysteine (Hcy) , hypersensitive C-reactive protein (hs-CRP) and calcitonin (PCT) detection in acute exacerbation of chronic obstructive pulmonary disease (AECOPD) .Methods Ninety-six patients with AECOPD were enrolled in this study.50healthy subjects were included in the healthy control group.Hs-cTnI was measured by electrochemiluminescence, Hcy level was measured by circulating enzyme method, hs-CRP level was determined by immunoturbidimetry, and colloidal gold blotting was performed.PCT levels, correlation analysis using Pearson correlation analysis, analysis of the correlation between the indicators and AECOPD, using ROC curve analysis of hs-cTnI, Hcy, hs-CRP, PCT diagnosis COPE acute exacerbation curve area (AUC) .Results The levels of hs-cTnI, hs-CRP and PCT in the AECOPD group were higher than those in the healthy control group (P<0.05) .The Hcy in the AECOPD group was lower than that in the healthy control group.The difference was not statistically significant (P>0.05) .Pearson correlation analysis shows that hs-cTnI, hsCRP and PCT were positively correlated with AECOPD (r=0.346, 0.401, 0.509) , and Hcy had a poor correlation with AECOPD (r=0.078) .In the ROC curve analysis, the area under the curve (AUC) for hs-cTnI, hsCRP, and PCT were 0.825, 0.834, and 0.922, respectively, The best diagnostic cut-off values were:0.082, 18.25, 3.075, and the sensitivities were 0.823, 0.802, and 0.781, respectively.The specificities were:0.92, 0.62, and 0.94.Youden′s index was 0.743, 0.422, and 0.721, respectively.The kappa values are:0.699, 0.423, 0.664.Conclusion The detection value of Hcy in the diagnosis of AECOPD is low.The detection of hs-cTnI, hsCRP and PCT has a certain diagnostic value in AECOPD.It can be used as an auxiliary diagnosis index of AECOPD.
