Can a 12 year old die of heart attack?

Quite rare, but not impossible for a 12 year old to die of heart attack. Very rare congenital abnormalities (birth defect) of coronary arteries (blood vessels supplying oxygenated blood to the heart) or aneurysms (localized enlargements) of coronary arteries due to Kawasaki’s disease (an inflammatory disease of childhood) can theoretically cause this.

Usually heart attack is a disease of older adults due to blockage of coronary arteries as a result of deposition of fatty material, which takes several decades to develop fully and obstruct the blood vessels.
