Utah mom of 2 Justine Carter, 33, had SCAD — a heart condition that can strike at any time in otherwise healthy people — and was saved by CPR.

In May, Justine Carter’s casual treadmill workout resulted in a shocking near-death experience, with the 33-year-old experiencing a heart attack 12 minutes in. At first, she started having shortness of breath, then a pain in her back extended to her chest, and moments later she began violently vomiting.
