Reid Park polar bear had heart condition

It's hard to tell if this cute little cub is Snow or her brother Klondike. The Denver Zoo raised them by hand after their mother rejected them. Lack of space in Denver sent them to SeaWorld Orlando. Snow transferred to Tucson recently so our climate could cure a skin condition.

TUCSON (KGUN9-TV) - Officials with the Reid Park Zoo have confirmed that Snow, the polar bear, died from an underlying heart condition.

Snow was found dead in her exhibit on Monday. Preliminary results from the necropsy confirm that she had an enlarged heart with scar tissue because of her condition.

Zoo officials believe she most likely had a heart arrhythmia in her sleep, leading to her death.

This condition does not show any symptoms and officials say it is not uncommon for this type of heart disease to be diagnosed after death.
