What's your typical image of someone having a heart attack, a man in his 50s, perhaps overweight?
You may be surprised to know more women die of heart disease than men, over 450,000 women a year.
The American Heart Association is hoping to get the word out with its "Go Red for Women" campaign.
Heart attacks and stroke have killed more women than men for the last 25 years.
But the American Heart Association found fewer than one in ten doctors knew that.
Which might explain why when women show up in the emergency room with chest pains.
They're less likely to get e-k-gs.
Or at the doctor, less likely to be prescribed life saving drugs that lower cholesterol.
Experts want women to speak up:
"We don't want women to be saying 'um, I'm not sure, but uh, you don't need to take care of me right away.' women need to be sure that they speak out and say 'listen, I'm concerned. I think I may be having a heart attack," said Dr. Susan Bennett of the American Heart Association.
The heart Association is asking women to wear red Friday to get the word out that heart disease is a big deal for women.
"Where did we get that image of the 50-year-old man grabbing his chest and clunk! falling on the ground?" asked Dr. Bennett.
Women often don't know they're having a heart attack because some never feel chest pain.
Experts say women are more likely to experience shortness of breath and pain in the upper back.
Even being overly tired can be a sign of heart disease.
