Advances in cardiac imaging techniques and risk categorization have led to improvements in diagnosis, initial treatment and long-term management of patients with Kawasaki Disease, according to a new scientific statement published today in the American Heart Association's flagship, peer-reviewed journal Circulation . The new statement, "Update on Diagnosis and Management of Kawasaki Disease," summarizes the data published since the 2017 American Heart Association Scientific Statement on Kawasaki Disease related to diagnostic criteria, risk scores and treatment options for children and adults with this condition. Statement highlights include: Kawasaki Disease is a rare but serious illness primarily affecting children younger than five years old.
