Abstract:
Objective To assess long-term outcomes of coronary artery (CA) Z scores in children with Kawasaki disease (KD) with echocardiography.Methods Echocardiographic data of 100 KD children during 7-14 years interval follow-up were analyzed retrospectively.The children were divided into dilatation group (n =54,CA dilated) and non-dilatation group (n=46,CA not dilated) at the acute phase.Fifty one children were selected simultaneously as the controls (control group).Diameters and Z scores of left main coronary artery (LMCA),left anterior descending (LAD) and proximal right coronary artery (pRCA) were compared,and factors affecting CA diameter during the recovery phase were analyzed.Results CA diameters in dilatation group were larger than those in non-dilatation group and control group (all P＜0.05),whereas no statistical difference of CA diameter was found between non-dilatation group and control group (all P＞0.05).In dilatation group,Z score of LMCA,LAD and pRCA was 0.569 5 ± 1.061 6,0.420 (-0.029,1.078) and 0.640(0.283,1.250),while in non dilatation group,Z score of LMCA,LAD and pRCA was-0.0313±0.8467,-0.0662±0.6612 and 0.1887±0.5935,respectively.In control group,Z score of LMCA,LAD and pRCA was-0.1246±1.0167,-0.2558±1.0848 and 0.1943±0.6101,respectively.Z scores in dilatation group were larger than those in non-dilatation group and control group (all P＜0.05),while no statistical differences of Z scores was found between nondilatation group and control group (all P＞0.05).Dilation degree of CA at the acute phase was the factor affecting longterm CA dilation (odds ratio=39.146,P＜0.001).Conclusion During 7-14 years of follow-up,CA diameters and Z scores kept to increase in KD children with CA dilatation at the acute phase.The dilation degree of CA at the acute phase in KD children affects the long-term CA dilation.
