Coronary Artery Diameters in Patients with Kawasaki Disease without Aneurysms by Two-dimensional Echocar diography in the Late Period

Abstract

We measured the diamters of coronary arteries in patients with Kawasaki disease (KD) without aneurysms by two- dimensional echocardiography (2-DE) in the late period. The diameters of the right coronary artery (RCA), the left main trunk (LMT) and the left anterior descending artery (LAD) were measured. We investigated simple regression between body surface area (BSA) and the diameters of three coronary arteries with KD without aneurysms. We compared the regression parameters of KD group with those of normal group. The number of KD group and normal group were 144 and 133, respectively. The ages ranged from 0 year to 19 years. The regression parameter of respective branches with KD group were shown. RCA=1.3 (BSA)+0.6 (r=0.84, p=0.001) LMT=1.5 (BSA)+1.2 (r=0.85, p=0.001) LAD=1.2 (BSA)+0.9 (r=0.81, p=0.001) The regression parameter of respective branches with normal group were shown. RCA=1.2 (BSA)+0.8 (r=0.88, p=0.001) LMT=1.4(BSA)+1.2 (r=0.89, p=0.001) LAD=1.1 (BSA)+0.9 (r=0.89, p=0.001) There were no significant defferences in respective brances with two groups. Coronary artery diameters in patients with KD without aneurysms by 2-DE in the late period are within normal limits.
