'Supernatural' Star Defies Death with Six Heart Attacks

'Supernatural' star Mark Sheppard experienced six deadly heart attacks and was brought back to life by EMTs. He had a 100% blockage in his left anterior descending artery, also known as a "widowmaker." Sheppard credits his wife and the team at St. Joseph's Hospital for his survival and expresses gratitude for feeling great and being able to go home soon. His co-star Misha Collins jokingly urges him to take it easy and get back on the road with them.
