背景:川崎病は冠動脈瘤の予防が重要であり,事前に冠動脈拡張リスクの高い患者を把握できれば治療上有用である.我々は川崎病患者に対して特定の心エコー所見を評価しているが,この変化により早期に冠動脈拡張を予測できる可能性があると考え,心エコー所見と冠動脈径Zスコア(Z)と関連性について検討した.

方法:川崎病で当科に入院した169例を対象に,入院期間中の三尖弁閉鎖不全,肺動脈弁閉鎖不全,僧帽弁閉鎖不全,大動脈弁閉鎖不全(AR),心嚢液(PE),左室拡張末期径,左室駆出率とZ≧2.5を満たす冠動脈拡張との関連性を検討した.

結果:AR, PE, LVDdの拡大は,単変量・多変量解析ともにZ≧2.5を満たす冠動脈拡張と有意な関連を示した.そのなかでARは冠動脈拡張以前に出現する割合が最も高く,Z≧2.5の冠動脈拡張に対する陽性適中率30%,感度42%,特異度76%であった.

結論:川崎病においてAR, PE, LVDd拡大は冠動脈拡張を伴う症例に多く,特にARについては発症早期に出現し,冠動脈拡張の予測に有用と考えられた.ARが認められた場合,速やかな治療開始が考慮される.

Background: The prevention of coronary artery aneurysm is important in the treatment of Kawasaki disease (KD). Thus, the ability to predict the risk of coronary dilation before initiating therapy would be very useful. In this study, patients suspected of KD underwent echocardiography and were evaluated for specific findings. We observed for specific changes that occurred in the course of KD, including when they appeared and their association with coronary dilation (Z ≥2.5).

Methods: We evaluated 169 patients diagnosed with KD. We analyzed the associations of coronary dilation with specific echocardiogram findings, including tricuspid regurgitation, pulmonary regurgitation, mitral regurgitation, aortic regurgitation (AR), pericardial effusion (PE), left ventricular end-diastolic diameter, and left ventricular ejection fraction, during hospitalization using univariate and multivariate analyses.

Results: Univariate and multivariate analyses showed that AR, PE, and left ventricular dilation were significantly associated with coronary dilation. Specifically, AR preceded coronary dilation, and its positive predictive value for coronary dilation was 30%, sensitivity was 42%, and specificity was 76%.

Conclusions: AR, PE, and left ventricular dilation were associated with coronary dilation, with AR preceding its occurrence. Therefore, patients with KD with AR early in the diagnosis require careful follow-up. Furthermore, prompt intravenous immunoglobulin therapy should be considered.

Key words: Kawasaki disease; coronary aneurysm; aortic regurgitation; pericardial effusion; left ventricular end-diastolic diameter
