Rosie O'Donnell is "happy to be alive" after suffering a heart attack last week.

“I am lucky to be here,” she wrote on her blog Monday.

O'Donnell, 50, wrote that she began experiencing symptoms, such as sore arms and an ache in her chest, on Tuesday after helping “an enormous woman/struggling to get out of her car.”

After a Google search suggested she was having a heart attack, O'Donnell said she took Bayer Aspirin, but did not call 911.

The next day, O'Donnell recalled, her doctor sent her to a hospital where a stent was put in, and she was also informed her that her “LAD was 99 percent blocked.”

“Know the symptoms ladies/listen to the voice inside/the one we all so easily ignore,” she wrote.
