Gabor's death certificate lists that she suffered a stroke, or cerebrovascular accident, before falling into a coma and dying of cardiopulmonary arrest at Ronald Reagan UCLA Medical Center. Other contributing factors to her death were coronary artery disease and cerebral vascular disease.

The 99-year-old star suffered several health issues in the final years of her life. She was in a coma for several days after a car accident in 2002 and survived strokes several years later in 2005 and 2007. In 2011, she had her right leg amputated, and in February 2016, suffered a feeding tube-related lung infection.

Gabor died on Dec. 18. Her husband, Frederic Prinz von Anhalt, told ET at the time that he was by her side at home, and "her heart just stopped."
