Myocardial infarction in a young adult due to Kawasaki disease. A case report and review of the late cardiological sequelae of Kawasaki disease.

Although Kawasaki disease is generally self-limiting, 15-25% of children with Kawasaki disease may develop significant cardiovascular sequelae, presentation may occur acutely or late (death has been reported up to 14 years after the acute illness). The most common late complication is the persistence of coronary artery aneurysms, these may produce myocardial ischaemia and even myocardial infarction, valvular dysfunction has also been reported. However the occurrence of late abnormalities of myocardial function is controversial. We describe a 24-year-old man who presented with myocardial infarction as a result of coronary artery aneurysms caused by Kawasaki disease, he gave no recent or childhood history of prodromal illness compatible with Kawasaki disease. The diagnosis was confirmed at post mortem.
