1999 IAAF World Indoor Championships. She lost the silver medal and was handed a two-year doping suspension. At the

IAAF in a Memorandum of 21 September 2005. Korzhanenko refused to return the gold medal, despite the pressure of the International Athletics Federation's officials. As of 2023, she has not returned the gold medal. ==International competitions==
