Back to school for students grieving the loss of classmate and friend: 15-year-old Freshman Running Back Ryan Gillyard.

Prep officials say the death was on this practice field during a Saturday morning conditioning workout.

It could take several months before officials learn the cause of death, but medical experts call this another opportunity to educate.

“If a parent comes to me and asks me if their child should be screened, I would say yes,” said Cardiologist Dr. David Shipon.

Cardiologist Dr. David Shipon heads Pennsylvania’s Athletic Health Organization. He points to several studies that say preventative care, beyond a simple sports physical, is now crucial.

It starts with screening and history.

“What are their risk factors for sudden cardiac arrest,” he asked. “And if there’s anything there, any warning sign or any historical data — absolutely — that person needs an EKG.”
