Rosie O'Donnell says she suffered a heart attack last week and is "lucky to be here".

The 50-year-old comedian detailed the experience on her blog on Monday, saying sudden nausea, aches and other symptoms pushed her to do an online search for "women's heart attack symptoms". She took a few aspirin and went to a cardiologist the next day.

She says her coronary artery was 99 per cent blocked. A stent was inserted.

O'Donnell writes in a kind of verse on her blog. She says: "Know the symptoms ladies/ listen to the voice inside/ the one we all so easily ignore."

The comedian recently hosted The Rosie Show on the Oprah Winfrey Network. It was cancelled in March.
