What inflammatory condition does Kawasaki disease primarily affect?

Kawasaki disease is primarily characterized by its effect on blood vessels, particularly the coronary arteries. This condition is a type of vasculitis, which means it causes inflammation of the blood vessel walls. The inflammatory response can lead to various complications, such as aneurysms in the coronary arteries if left untreated, which is why it's critical to identify and manage the disease early.

In the case of Kawasaki disease, the inflammation extends beyond just one specific area or type of tissue—it specifically targets the medium-sized arteries throughout the body, but the coronary arteries are of particular concern due to their role in supplying blood to the heart muscle. The disease usually occurs in children and can result in serious cardiovascular complications if not addressed, making recognition of its vascular impacts essential for appropriate medical intervention.
