A man is dead after participating in a Mount Everest-themed endurance challenge.
Slava Leykind died at age 43 on July 2 “from complications sustained” at the event, according to his online obituary.
Teton County Coroner Brent Blue told Jackson Hole News and Guide the cause of death was “an electrolyte imbalance causing cardiac arrest.”
Per the outlet, Leykind died at Eastern Idaho Regional Medical Center in Idaho Falls, where he was brought from Snow King Mountain in Jackson, Wyo. He was later buried near his home in Westport, Conn.
Local authorities, event organizers and the county coroner did not respond to PEOPLE’s request for comment.

The event that Leykind took part in before his death, 29029 Everesting, is named after the summit elevation of the Earth’s highest peak.
Held from June 26 to June 29, hikers travel about 1,500 feet up the mountain, enough times to mimic the height of Mount Everest, which is located between China and Nepal.
According to Jackson Hole News and Guide, event organizers sent a message out to participants following the tragedy. “Today is an incredibly sad day for our community, as a Jackson Hole participant has passed away,” the message read, per the outlet.

In his obituary, Leykind — who moved with family from the Soviet Union to Minneapolis in 1988 — was remembered as “a perfect soulmate for over two decades to Amy Keller Leykind, and superhuman father to Charlotte, Eloise and Jonah Leykind.”
“Despite his significant professional success at a young age, Slava’s role as a husband and father was his greatest achievement, passion and pride,” the tribute continued, referencing Leykind’s role as a banking industry leader. “He fervently supported his children, bringing love and a sense of calm to the wonderful chaos of a full house.”
