Why does Kawasaki disease cause coronary artery dilatation

Kawasaki disease is mainly due to coronary artery dilatation caused by its mediated immune mechanism, and once you have Kawasaki disease you need to seek medical attention to avoid complications.
Kawasaki disease, also known as pediatric cutaneous mucocutaneous lymph node syndrome, is a self-limiting disease that is mediated by the body’s immune mechanisms leading to the development of systemic vasculitis. Kawasaki disease particularly affects the coronary arteries, causing coronary artery dilatation and even coronary artery aneurysms and coronary artery embolism, with negative consequences.
Therefore, in the treatment of Kawasaki disease, it is necessary to pay particular attention to the coronary arteries, not only to control systemic vasculitis, but also to minimize the damage to the coronary arteries. Commonly used medications include aspirin, glucocorticoids, immunoglobulins, etc.
