Luckily for the 61-year-old Novi man that collapsed on the golf course, the golfers behind him were doctors. ER doctor Chris Cooley and his gastroenterologist brother Matt acted off of instinct and sprinted to the man when they heard of the need for help. According to FOX 2 Detroit, the Cooley brothers performed CPR on the golfer, David Wujczyk, to keep oxygen flowing to the brain. The brothers credit the Southfield firefighters heavily for quick response time. Wujczyk was taken to Providence Hospital where it was discovered that he had 100% blockage of what's called the Widow Maker.
