Heart attacks affect both men and women, of course, but women are more likely to have non-traditional symptoms that might make them question the need to get to the ER.
I could parrot back a lot of info, but today I read someone else's blogpost that does it better than anything I could write here.
Megan over at Stellar Four shares her personal story, the warning signs of a heart attack, and also some awesome heart necklaces too. http://www.stellarfour.com/2012/02/go-red-and-geeky-for-women.html
Share the info with your friends and family. Know the signs. Maybe put on a red shirt, necklace, dress, shoes - let's get the word out!
