Kawasaki disease can cause blood clots in the arteries that may lead to a heart attack or internal bleeding if left untreated.
Is it true that Kawasaki disease can cause blood clots in the arteries that may lead to a heart attack or internal bleeding if left untreated?
Yes. Kawasaki disease can lead to severe coronary artery abnormalities, such as aneurysms and thrombosis, which increase the risk of myocardial infarction and ischemic heart complications.
Verdict: SUPPORTED · 8 sources for, 0 against · Last checked
The retrieved papers consistently document that Kawasaki disease can cause coronary artery aneurysms, thrombosis, and stenosis, which lead to acute coronary syndromes, myocardial infarction, and ischemia if not properly managed. There are no papers refuting this well-established clinical consensus.
