Kawasaki Disease
Kawasaki disease is a disease that affects children. It is also known as Kawasaki syndrome or mucocutaneous lymph node syndrome. Kawasaki disease leads to swelling (inflammation) of the body’s tissues. Doctors do not know what causes Kawasaki disease, but if it is not treated, it can lead to inflammation of the heart and the coronary arteries. This inflammation can lead to long-term heart problems such as blood clots, aneurysms, or a heart attack.
Kawasaki disease most often affects the coronary arteries, usually by weakening their walls. If an artery’s wall is weakened, the pressure of blood passing through it forces the artery to bulge outward, forming what you might think of as a thin-skinned blister. This is called an aneurysm. If a blood clot forms in the aneurysm, it can block the artery, leading to a heart attack. In rare cases, the aneurysm may burst.
Kawasaki disease may also cause inflammation of the heart muscle (called myocarditis) or the sac surrounding the heart (called pericarditis). It can also lead to abnormal heart rhythms (arrhythmias).
For most children, the heart problems go away after 5 or 6 weeks, and there is no lasting damage. In some children, the coronary arteries are damaged forever.
