Igor Vovkovinskiy, the tallest man in the United States, died of a heart disease on Aug. 20 at 38 years old.
Ukrainian-born Vovkovinskiy died at the Mayo Clinic in Rochester, Minnesota, according to Vovkovinskiy’s mother, Svetlana, on Facebook.
In 2010, the Guinness World Records declared Vovkovinskiy as the tallest man in the U.S. when he appeared in the Dr. Oz show. He stood at 7 feet and 8.33 inches (2.35 meters).
Vovkovinskiy had moved to Rochester from Ukraine in 1989 to seek for medical treatment for a tumor pressing against his pituitary gland, which caused it to secrete abnormal levels of growth hormone.
Vovkovinskiy gained national attention in 2009 when former President Barack Obama noticed him during a campaign rally where he wore a shirt that read, “World’s Biggest Obama Supporter.”
