川崎病後遺症によると思われる成人狭心症の1例

An adult case of angina pectoris as a sequel of Kawasaki disease

　川崎病は乳幼児に好発する急性の血管炎症候群の一つであるが，冠動脈が高率に侵され^1〜3），冠動脈病変の残存はその予後を左右すると言われている。1967年，本症が初めて報告^4）されて以来，すでに20年が経過しているが，今後，本症の既往を有する成人例が増加し，内科領域でも川崎病後遺症による冠動脈病変を有する患者を扱う機会が増えることが予想される。今同，我々は，川崎病後遺症によると思われる狭心症の1成人例を経験したので報告する。

A 20 year-old man who had a history of Kawasaki disease at the age of nine years was admitted to our hospital because of recurrent chest oppression. Al-though electrocardiograms both at rest and during exercise as well as thallium-201 myocardial scanning revealed no abnormal findings, selective coronary arteriogram demonstrated severe stenotic lesion in the right coronary artery, which extended from the orifice to the distal portion. Since there were no other coronary risk factors responsible for athero-sclerosis, we made a diagnosis of angina pectoris as a sequel of Kawasaki disease.

It is emphasized that many of adult persons who have experienced Kawasaki disease in their childhood may develop coronary artery disease in the future.
