After googling her symptoms, Rosie O'Donnell thought she might be having heart attack. Instead of calling 911 or going to the hospital, the comedian/talk show host/actress took aspirin and went to see her cardiologist the next day (she'd seen a TV commercial advising aspirin if feeling heart attack symptoms). It turns out O'Donnell, 50, definitely had a heart attack. Her doctor inserted a stent to open her coronary artery, which was 99 percent blocked. Being that heart disease is the number one killer of women, we suggest to O'Donnell -- or anyone -- if you think you're having a heart attack call 911 immediately.
