Here's a link to an article about Rosie O'Donnell.
I find the wording "odd" . . . "she says she had a heart attack." It almost sounds as though the article is doubting it was a heart attack. And no doctor actually confirms it. She went to a cardiologist the next day, and they put in a stent. If I googled the symptoms of a heart attack and was concerned enough that I took aspirin (as the article would have recommended), I would have called 911 and/or immediately gone to an emergency room. I think she may have had a blockage, but not all blockage = heart attack.
