Rosie O'Donnell revealed she suffered a heart attack last week and called it a "miracle" she didn't die.

The comedian shared the news on her blog and credited a Bayer aspirin commercial with saving her life.

"i took some bayer aspirin/thank god/saved by a tv commercial/literally," O'Donnell wrote in her usual free verse form.

O'Donnell said she Googled the symptoms of a heart attack and was experiencing many of them, yet she did not call 911.

The pain persisted, O'Donnell said. The next day she visited a cardiologist who did an EKG and found her coronary artery was 99 percent blocked.

O'Donnell was admitted to the hospital and had a stent put in to clear the blockage.

"they call this type of heart attack/the Widow Maker/i am lucky to be here," she wrote.

Earlier this month, O'Donnell revealed her fiancee, Michelle Rounds, had been diagnosed with desmoid tumors, a rare condition. The condition, which affects about 900 people in the U.S. each year, produces slow growing tumors in the body that can cause life threatening conditions if they compress vital organs.

"Undiagnosed - again and again / her pain grew worse / it seemed impossible / no one knew what was wrong," O'Donnell wrote. "Life changes in an instant."
