This article discusses a case report of a young adult who experienced severe cardiovascular complications as a result of Kawasaki disease (KD), a pediatric illness that primarily affects children under the age of 5. The patient had a history of KD and was treated with intravenous immunoglobulin (IVIG), but still developed significant cardiovascular issues later in life. The article emphasizes the importance of early recognition, treatment, and long-term follow-up for patients with KD to prevent these complications. The given text references two medical articles that discuss the mortality rates and follow-up care for individuals with a history of Kawasaki disease in Japan, which may be useful for library patrons researching the long-term effects and management of the disease.
