The present study aimed to examine the correlation of D-dimer levels with the Child-Pugh and MELD scores, as well as to determine the predictive ability of D-dimer level for the in-hospital mortality of liver cirrhosis patients. All cirrhotic patients who were consecutively admitted to our hospital between January 2011 and June 2014, and underwent D-dimer tests on admission were retrospectively analyzed. Pearson's f tests were employed to evaluate the correlations of D-dimer levels with Child-Pugh and MELD scores. In addition, receiver operating curve (ROC) analysis was employed to evaluate the specificity and sensitivity of D-dimer levels for predicting the in-hospital mortality. In total, 703 cirrhotic patients were included in the study, with an in-hospital mortality of 5.4% (38/703). The D-dimer levels were correlated with Child-Pugh (correlation coefficient, 0.219; P<0.001) and MELD scores (correlation coefficient, 0.207; P<0.001). The highest D-dimer level was observed in the Child-Pugh class C patients, followed by the class B and A patients. Furthermore, D-dimer was significantly higher in the MELD score >15 group compared with the MELD score <15 group. The area under the ROC of D-dimer levels for predicting the in-hospital mortality of liver cirrhosis was 0.729 (P<0.0001), while the best cut-off D-dimer value was 0.28 mu g/ml with a sensitivity of 86.84% and a specificity of 49.17%. In conclusion, the D-dimer level is significantly associated with the degree of liver dysfunction. Therefore, D-dimer testing could be employed for the prognostic stratification of liver cirrhosis.
