Kawasaki Disease and Heart Health
According to the American Heart Association, the heart may be affected in as many as one in four children who have Kawasaki disease.
Damage to the heart may sometimes occur in the blood vessels that supply the heart muscle (coronary arteries) and to the heart muscle itself. Coronary artery damage can result in an enlargement or swelling of the blood vessel wall (an aneurysm). Infants less than one-year-old are at higher risk for heart complications than older children and adults during KD.
The following video explains the course of Kawasaki disease within the coronary arteries.
