In children, which of these is a common complication of Kawasaki disease?

Kawasaki disease is a pediatric inflammatory condition that primarily affects the blood vessels, particularly those supplying the heart, and is characterized by prolonged fever, rash, conjunctivitis, and other systemic symptoms. One of the most significant complications associated with Kawasaki disease is the development of coronary artery aneurysms.

This occurs due to inflammation of the arterial walls, which can weaken them and lead to the formation of aneurysms, or bulges, in the coronary arteries. These aneurysms can cause serious cardiovascular problems, including ischemia, myocardial infarction, and increased risks of sudden cardiac events later in life. Recognizing the potential for coronary artery complications is crucial in the management of patients with Kawasaki disease, as it influences treatment strategies and monitoring.

In contrast, bradycardia, anemia, and diabetes mellitus are not commonly associated complications of Kawasaki disease. While bradycardia can occur in various medical conditions, it is not a direct result of Kawasaki disease. Similarly, while anemia may occur due to other underlying conditions or chronic illness, it is not a specific complication linked to Kawasaki disease. Diabetes mellitus is unrelated to Kawasaki disease, as it is a metabolic disorder and not a direct consequence of the inflammatory processes involved in this condition.
