It's no mystery why so many people think heart disease is a man's issue. In movies and TV, it's almost always the men who have heart attacks. In the news, heart-health stories are mostly geared toward men. And, until fairly recently, even science has focused on men's hearts, not women's.
But a lot of that is starting to change. Why? Because heart disease is the No. 1 cause of death in women. It kills more women than all forms of cancer combined [source: Ricciotti].
This may be at least partly due to a lack of public knowledge on the topic: Women have different symptoms during a heart attack, and they may not recognize them because they're looking for the ones that men experience [source: Ricciotti].
Research is also starting to reveal that women's hearts may function differently from men's, a factor that could contribute to a woman's 50-percent greater chance of dying during heart surgery [source: Ricciotti].
And finally, a debunking that's going to be very, very difficult to believe if you have a kid.
