Clinical data of patients by follow-up results are in Table 2. The status of coronary arteryAssociations of DKK-1 and Risk Stratification by GRACE ScoreThe medium concentrations of DKK-1 were 642, 718 and 959 pg/ml for low, intermediate and high GRACE category, respectively (Fig. 4).

The median GRACE risk score was 88 (range 38?49) for the whole population, 108 (63?49) for patients with STEMI, 84 (38?148) for patients with NSTE-ACS, 89 (46?40) for patients with MACE and 88 (38?49) for patients without MACE. The GRACE scores were significantly higher for patients with STEMI than NSTE-ACS at baseline (P,0.001). MACE and non-MACE groups did not differ in GRACE scores (P = 0.570).3.176?2.487, P,0.001; 1.395, 1.072?.815, P = 0.013, respectively, Table 3).DKK-1 has Better Prognostic Value for Patients with ACSA 3-step process was used for ROC analysis: GRACE score alone, GRACE score with DKK-1 or hs-CRP level, and GRACE score with both biomarkers. The GRACE score alone was a poor predictor of MACE (with area under the ROC [AUC] 0.524). With the addition of DKK-1 level, the AUC was increased to 0.775 and to 0.791 with hs-CRP level. With both biomarkers added, the AUC was significantly increased to 0.847, and the sensitivity of this model in evaluating prognosis was 81.8 , with specificity 71.7 (Fig. 5).DKK-1 is an Independent Predictor of Long-term MACE for Patients with EAI045 web ACSAfter adjustment for cardiovascular risk factors, binary logistic regression revealed a significant association of DKK-1 and hsCRP levels and MACE for ACS patients (OR 8.451, 95 CIDiscussionDKK-1, as a major regulator of the Wnt pathway, plays a key role in cardiovascular disease. We investigated the association of DKK-1 in ACS and whether the GRACE hospital-discharge risk score for MACE could be improved by adding the DKK-1 value. We also investigated an association of DKK-1 level and MACE at 2-year follow-up. Plasma DKK-1 level at baseline was higher for patients with than without STEMI and was correlated with hsCRP level. Plasma DKK-1 level was higher with high than intermediate or low GRACE scores and was higher for patients with than without MACE. The AUC for GRACE score predicting MACE was best with both hs-CRP and DKK-1 levels added. Plasma levels of DKK-1 may be useful for identifying and for longterm prediction for patients with ACS at high risk of MACE, especially when combined with hs-CRP for the GRACE score.
