Abstract

Kawasaki disease is an acute febrile illness of unknown origin and most frequently affects infants and children younger than age 5 years. Coronary aneurysms are most serious complication in Kawasai diseas and are developed in 15〜20% of patients. We studied 15 children Kawaski disease complicating coronary aneurysms, who were admitted to the Kyung Hee University Hospital during the period of January 1984 through January 1988. The results were as follows. 1) The ratio of male to female was 2.7:1. 2) The peak incidence of age was 2〜 2n/12 years (33.3%). 3) The mean duration of fever was 10.6 ±3.5 days and the duration between 11 and 15 days was most common (46.6%). 4) The abnormal laboratory findings, which occured most frequently on admission were throm- bocytosis (93.3%) and elevation of cESR (93.3%). 5) The abnormal EKG findings on admission were occured in 80% of patients and were prolonged PR interval (40.0%), prolonged QTc interval (33.4%), abnormal Q wave (13.3%), flat T wave (6.7%), ST elevation (6.7%), right ventricular hypertrophy (6.7%) and left ventricular hypertrophy (6.7%). 6) The %FS (percent fractional shortening) of patients was significantly lower than that of controls but PWe/LSe (ratio of left posterior wall to left septal exursion) and STI (systoloic time interval) were not sighificantly different between patients and controls. 7) The sites of coronary aneurysms were left coronary artery (66.7%), combination of left coronary artery and right coronary artery (20.0%) and right coronary artery (13.3%). 8) The fusiform coronary aneurysms (66.7%) were more common than saccular coronary aneuyr- ysms (33.3%).
