Kawasaki Disease (cont.)

What is the prognosis for Kawasaki disease?

Kawasaki disease is the most common cause of acquired heart disease in children in the developed world. When diagnosed and treated early, the incidence of coronary artery lesions decreases from 20% to 5%. It is very uncommon for patients who have no evidence of coronary abnormalities at two to three months after the acute illness to develop coronary abnormalities. Patients with larger coronary lesions have the greatest risk, and it has been shown that patients with giant aneurysms (>8mm) have a highest risk of developing future heart attacks (myocardial infarctions). The long-term risk of patients with small aneurysms is currently unknown.
