A medical examiner in Arizona has released details of the death of Alexander Dale Oen, according to Reuters, and has declared atherosclerotic coronary artery disease as the official cause of death.
“Based on the autopsy findings and the investigative history that is available to me, it is my opinion that Alexander Dale-Oen died of atherosclerotic coronary artery disease,” Coconino County medical examiner Lawrence Czarnecki said in his official report.
The report went on to point to a blood clot in one of his arteries as the more specific cause of the attack.
Dale Oen, a Norwegian, was the 2011 World Champion in the 100 breaststroke. He passed away while on a training camp in late April in Flagstaff, Arizona.
Coronary artery disease is the most common cause of death in the world.
