The 21-year-old USC student, who had a heart attack at the Los Angeles Marathon, the LAPD motorcycle officer who saved his life, and the UCLA physicians who treated him, gathered together at UCLA Thursday to celebrate his life and their success.

Jay Yim, a pre-med student originally from Phoenix, went into cardiac arrest at the 18-mile mark of the marathon. LAPD motorcycle officer Joshua Sewell saw Yim go down and immediately rush over to his aide. Although Sewell had already helped four other runners who had collapsed, this time was different. Yim was not responding. Sewell called for an ambulance and immediately started delivering CPR.

In the meantime, Dr. Charles Chandler, chief of surgery at the Santa Monica UCLA Medical Center, arrived on the scene. He had been watching the race from a window at his home when he saw Yim go down. Chandler helped administer CPR until more help arrived.

Yim was first treated at the UCLA Neurointensive Care Unit where he was put into a state of therapeutic hypothermia, a treatment that lowers a patient’s body temperature to help reduce the risk of tissue injury following a heart attack. Although the hypothermia practice is controversial, it seems to have helped Yim’s case. He has since been moved from the intensive care unit and should be released from the hospital in the next few days to begin rehabilitation.
