Abstract: Objective To investigate the incidence of coronary artery injury in children with Kawasaki disease（KD）and analyze the risk factors．Methods From January 2018 to December 2022,782 children with KD diagnosed and treated in Quanzhou Women’s and Children’s Hospital were selected as the study subjects．All the children were given ultrasound examination on admission to determine the coronary artery injury level．The general information of all the children was investigated and the risk factors were analyzed．Results Among the 782 children,171 cases（21.9%）were diagnosed as the“coronary artery injury group”．The remaining 611 patients did not exhibit any coronary artery injury and were thus categorized as the“no coronary artery injury group”．The clinical manifestations incidences of rashes,hard red swelling of extremity,bulbar conjunctival congestion and bayberry tongue in the coronary injury group were 83.6%,67.8%,86.0% and 81.9%,respectively,which were significantly higher than those in the non-coronary injury group（63.5%,49.7%,62.5% and 65.3%,P<0.05）．There were no significant differences in gender,age,hemoglobin and erythrocyte sedimentation rate between the coronary injury group and the no coronary injury group（P>0.05）．There were significant differences in alanine aminotransferase,white blood cell count（WBC）,D-dimer（D-D）,C-reactive protein（CRP）,procalcitonin（PCT）,platelet count（PLT）and fever duration between the two groups（P<0.05）．Multivariate Logistic stepwise regression analysis showed that WBC,D-D,CRP,PCT and PLT were all important factors leading to coronary artery injury（P<0.05）．Conclusions The incidence of coronary artery injury in children with KD is relatively high,which can lead to the diversification of clinical features and disease aggravation of children．WBC,D-D,CRP,PCT,PLT and fever duration are important risk factors for the occurrence of coronary artery injury．
