Pediatric sudden cardiac arrest kills nearly 2,000 people under the age of 25 every year, according to the AAP.

Dr. Randall Caldwell, director of pediatric cardiology at Riley Hospital for Children, told WIBC that screening children for heart problems early on can save lives down the road.

"If you take a look at those 2,000 patients (who died), about 56 percent are going to be related to a death from some cardiovascular problems," he said. "That's why we want to make sure we screen those children and take care of those type of problems."

Caldwell said Riley treats about 30 new children each week complaining of chest pain, but only about 3 to 5 percent of them are found to have a heart issue.

Still, he said it's important that parents know about heart issues in their families and get children screened for heart health when they begin playing sports or when they reach second or third grade.

Exercise increases the risk for sudden cardiac arrest, as well as extremes in hot and cold temperatures.

"The No. 1 problem is called hypertrophic obstructive cardio myopathy, where the heart muscle is very muscle bound or thickened," he said. "That happens in about one of every 500 individuals, so that's the problem we make sure we want to screen for."
