Bulent Sonmez (40) from Ankara, Turkey, had gone to hospital complaining of pain in his arm and suddenly collapsed with a heart attack. Doctors quickly attended to him but his heart stopped.
Doctors decided to use a controversial therapeutic hypothermia treatment to lower his body temperature and immersed him in ice bath to limit the effects of a lack of oxygen on the organs. The 40-year-old was in ice bath as his body slowly reduced in temperature to 30C.
Doctors then restarted his heart and spent 24 hours maintaining his heart rate and returning his body temperature to normal.
Despite its success, the 40-year-old could only remember around half his life and had no recollection of his wife and children. He was said to have woken up believing he was 20 years old.
Bulent's wife Sibel Sonmez (39), said, "It was like a movie, I didn't know how to explain the two children we had waiting at home. I tried to resolve it by showing him photographs, but it took a very long time to be able to convince him."
Dr Omer Zuhtu, said, "We did not find much literature looking in detail at the side effects of therapeutic hypothermia treatment. It remains a controversial procedure but we believe in this case it certainly saved this man's life."
