A recent study from Stanford Medicine shows death from heart attacks have dropped overall, but heart attacks are becoming more prevalent in young adults. A student at East Carolina University, and member of the track team, lived through a heart attack at just 21-years-old. The experience has turned her into an advocate for AED and CPR training, which can make a life-or-death difference. Hailey Yentz, the former ECU runner, shared her experience from last winter with Jeff Hamlin.
