Rosie O'Donnell is lucky to be alive -- the 50-year-old talk show host/actress revealed Monday that she had a heart attack last week. In her typical poetic style, she wrote the following blog post titled "my heart attack," about what happened after she helped an "enormous woman" who was struggling to get out of her car:

"a few hours later my body hurt
i had an ache in my chest
both my arms were sore
everything felt bruised."

She continues,

"i became nauseous
my skin was clammy
i was very very hot
i threw up

maybe this is a heart attack
i googled womens heart attack symptoms
i had many of them
but really? – i thought – naaaa

i took some bayer aspirin
thank god
saved by a tv commercial"
