A 43-year-old Nevada man collapsed and died on the court during a tennis match at Red Rock Country Club on January 29, the Las Vegas Review-Journal reported.
Ryan Vannah was pronounced dead at Summerlin Hospital later in the day.
"He took impeccable care of his health," Tami Vannah Kang, the deceased man's sister, told LVRJ. "We did not see this coming," she added.
Ryan Vannah reportedly "dropped to a knee" during a tiebreaker mixed doubles match, placed his hands on the court, and lay down.
Despite doctors' best efforts to revive the Red Rock Country Club tennis champion, they were unable to restart his heart.
Vannah's sister-in-law, Dr. Catherine Vannah, was among the people who attempted to revive him on the scene, according to LVRJ.
The coroner's office had not ruled on an official cause of death as of Tuesday, LVRJ reported. However, Summerlin Hospital medical staff said they believed he was on the wrong medication for his blood pressure.
Vannah was a lifelong tennis player who won United States Tennis Association championships in doubles in for the past two years.
He is survived by his parents, three siblings, a fiancée, two brothers-in-law, a sister-in-law, and 13 nieces and nephews, LVRJ also reported.
A memorial service will be held for Vannah at 10 a.m. on February 11 at The Church of Jesus Christ of Latter-day Saints in Las Vegas.
Vannah's death comes on the heels of a number of instances in which young, seemingly healthy athletes and non-athletes have suffered strokes, heart attacks, and similar medical emergencies, with some losing their lives.
There is considerable controversy regarding these reports, with some insisting there has been no spike in deaths among athletes at all.
Some medical professionals suspect the issues are related to COVID vaccine side effects like myocarditis, an inflammation of the heart muscle. Other medical professionals passionately deny the theory, calling it a "hoax."
Florida Surgeon General Joe Ladapo tweeted about an analysis pointing to a high incidence of cardiac-related deaths among COVID-vaccined young men in September 2022. Twitter first blocked the post and later restored it, Politico reported.
Buffalo Bills defensive back Damar Hamlin is one athlete in this category. He suffered cardiac arrest on January 2, 2023, after tackling Cincinnati Bengals wide receiver Tee Higgins.
Inspired by the quick medical attention that saved Hamlin, the NFL and the American Heart Association are providing free CPR education during Super Bowl week, ESPN reported.
