What does Kawasaki disease do to the heart?

Kawasaki disease leads to swelling (inflammation) of the body’s tissues and if left untreated, 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.

Does Kawasaki disease affect the heart?

Kawasaki disease is a leading cause of acquired heart disease in children in developed countries. However, with treatment, few children have lasting damage. Heart complications include: Inflammation of blood vessels, usually the coronary arteries, that supply blood to the heart.

How does Kawasaki disease affect my child’s heart and blood vessels?

If Kawasaki disease is left untreated, it can lead to serious complications such as inflammation of the blood vessels. This can be particularly dangerous because it can affect the coronary arteries–the blood vessels that supply blood to the heart muscle–causing coronary artery aneurysms to develop.

What is the main complication of Kawasaki disease?

Aneurysms of the coronary arteries, the blood vessels that supply oxygen to the heart itself, are the most important complication of Kawasaki disease. With appropriate and timely treatment, the risk of coronary artery involvement decreases to around 5 percent.

What happens if Kawasaki disease goes untreated?

Kawasaki Disease begins suddenly. The disease can cause blood vessels to become inflamed or swollen throughout the body. If untreated, the swelling can lead to damage of the blood vessel walls, especially those that go to the heart (coronary arteries). A section of a blood vessel wall can balloon out and become weak.

Can Kawasaki cause heart murmur?

On clinical examination there is a hyperdynamic precordium, tachycardia, gallop rhythm, flow murmur due to anemia, pansystolic murmur due to mitral regurgitation, low contractility due to myocarditis and occasionally low cardiac output or shock.

Can you have side effects of Kawasaki disease later in life?

Long-term effects of Kawasaki disease, however, can include heart valve issues, abnormal heartbeat rhythm, inflammation of the heart muscle, and aneurysms (bulges in blood vessels). These lasting heart conditions are rare. Less than 2% of patients experience coronary artery enlargement that carries over into adulthood.

Can Kawasaki cause mental illness?

The reported behavioral difficulties may be due to residual central nervous system effects of the disease process, the experience of an acute illness and hospitalization, and/or continued family anxiety after the illness.

Can Kawasaki disease go away by itself?

Kawasaki disease often goes away on its own, but if it is not treated it can cause serious injury to the heart and other organs. In some cases, the disease can affect the coronary arteries, which are blood vessels that supply oxygen-rich blood to the heart.

Is Covid causing Kawasaki disease?

A significant number of patients were exposed to someone with COVID-19 infection. A key finding of PMIS is evidence of severe inflammation, which is similar to Kawasaki Disease and like Kawasaki Disease, children with PMIS also have high fevers and can present with red eyes, and rash.

How does Kawasaki disease cause coronary aneurysms?

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.

Does Kawasaki disease affect the brain?

Kawasaki disease is an acute vasculitis, that has a classic complication of acquired coronary artery aneurysm. Severe forms with multi-organ involvement or neurological dysfunction are rare. Cerebral vascular involvement has been related to large-vessel injury or cardioembolism, leading to focal brain infarction.

Is Kawasaki disease painful?

Both eyes are usually affected, but the condition isn’t painful.
