Objective To investigate the significances of PAMP and NT-proBNP in predicting coronary artery injury in Kawasaki disease(KD).Methods A total of 196 cases of KD in this hospital from February 2014 to August 2015 were selected and divided into the KD injury group and KD non-injury group according to with orwithout coronary arterial injury.Contemporaneous 50 healthy children in the Child Health Care Center were selected as the control group.The plasma levels of PAMP and NT-proBNP were detected in 3 groups.Results Compared with the control group,the plasma levels of PAMP and NT-proBNP in the childrenpatients with KD were increased,moreover the KD injury group was higher than the KD non-injury group(P＜0.05).The plasma PAMP levels in KD children patients were positively correlated with NT-proBNP,white blood cell(WBC) count,neutrophil percentage and erythrocyte sedimentation rate(ESR)(P＜0.05),while were negatively correlated with the value of serum sodium and albumin(P＜0.05),the plasma levels of NT-proBNP were positively correlated white blood cell count,neutrophil percentage,C-reactive protein(CRP) and ESR(P＜0.05),while were negatively correlated with the levels of serum sodium and albumin(P＜0.05).The area under the curve(AUC) of plasma PAMP and NT-proBNP levels in predicting coronary artery damage in children patients with KD was 0.989,the sensitivity was 93.24％ and specificity was 93.65 ％.Conclusion The plasma levels of PAMP and NT-proBNP in children patients with acute phase of KD are elevated,which can serve as the predictive indicators of coronary artery lesion.
