While a child's heart attack seems unthinkable, the sobering reality is that pediatric myocardial infarction strikes hundreds of children annually, driven by causes from congenital defects and Kawasaki disease to rising threats like obesity and vaping, with survival and long-term outcomes heavily dependent on timely, specialized intervention.

- Globally, pediatric myocardial infarction accounts for less than 1% of all childhood hospitalizations for chest pain, with rates varying by region
- Among neonates, the incidence of perinatal myocardial infarction is estimated at 1 in 25,000 live births due to maternal factors

- Type 1 diabetes increases MI risk by 10-fold in children under 18 compared to peers
- Kawasaki disease patients have a 5-10% risk of developing coronary aneurysms leading to MI
- In-hospital mortality for pediatric MI is 8.5%, higher than adult rates adjusted for age

- Kawasaki-related MI has a 22% mortality rate in untreated giant aneurysms
- Males account for 60% of pediatric MI cases under 18 years
- Children aged 10-17 years represent 45% of all pediatric MI hospitalizations
- African American children have 2.3 times higher MI incidence than Caucasians
