I had kawasaki disease when i was a kid, will that cause me to have heart problems as an adult?

Possibly: If you had any coronary involvement from the disease you should have been followed periodically all along, as you are at risk. If you appear to have completely recovered with no evidence of any coronary involvement, there is some concern that you may be at risk for premature coronary disease as an adult. Your primary physician needs to be aware of your history to appropriately advise you.
