American comedian and chat show host Rosie O'Donnell, who suffered a heart attack last week, has said it is a "miracle" she is still alive - and credited the internet for saving her life.
The 50-year-old, a regular celebrity blogger and gay rights activist, researched her early symptoms, which began at the start of this month, online.
O'Donnell said she had a stent inserted after doctors found that her coronary artery was 99% blocked.
She also revealed that Bayer Aspirin aided her successful recovery, after seeing the consumer product advertised.
O'Donnell wrote on her blog: "Thank god/saved by a tv commercial/literally.
She added: "Know the symptoms ladies listen to the voice inside the one we all so easily ignore CALL 911.
"Save urself xxx."
O'Donnell's agent Cindi Berger told People magazine: "She is now home and resting comfortably. She is very, very lucky."
"They call this type of heart attack/the Widow Maker/I am lucky to be here."
Earlier this month, O'Donnell revealed that her fiancée Michelle Rounds was diagnosed with desmoid tumours, known as being a very rare condition.
O'Donnell said she first noticed her health problems after overexerting herself by helping a struggling woman get out of her car in a New York car park.
