Does Abciximab Enhance Regression of Coronary Aneurysms Resulting From Kawasaki Disease?
Objective. Acute Kawasaki disease can result in the development of large coronary artery aneurysms that may persist. Abciximab, a platelet glycoprotein IIb/IIIa receptor inhibitor, is associated with resolution of thrombi and vascular remodeling in adults with acute coronary syndromes. The purpose of this study was to compare changes in aneurysm diameter at early follow-up in patients who had Kawasaki disease and received abciximab in addition to standard therapy with those who were treated with standard therapy alone. Methods. Patients with Kawasaki disease and large aneurysms were divided into 2 groups on the basis of acute therapy: 1) abciximab in addition to standard therapy and 2) standard therapy alone. Echocardiograms were reviewed for coronary aneurysms (lumen diameter 1.5 times that of the adjacent vessel). Maximum aneurysm diameter was determined during the acute/subacute phase of Kawasaki disease (<6 weeks) and at early follow-up (4 6 months). Regression of the aneurysm was
