(NEW YORK) -- Joan Rivers has been unconscious since her arrival three days ago at a New York City hospital, but her daughter expressed hope on Sunday that the 81-year-old comedian will recover from her illness.
"Thank you for your continued love and support," Melissa Rivers said in a statement on Sunday. "We are keeping our fingers crossed."
Her mother arrived at Mount Sinai Hospital Thursday after an emergency call that she was in cardiac arrest at an Upper East Side clinic, Yorkville Endoscopy, sources said.
Doctors are intentionally keeping her sedated and under close supervision until they're more comfortable with her condition, which remains "serious."
