Pregnancy can increase a woman's chance of dying from a heart attack.

 

 

     That's according to a new study cited in USA today.

 

 

     Researchers from the University of Southern California found heart attacks in pregnant women are three times more fatal than in a woman who isn't pregnant.

 

 

     Seven percent of pregnant women die from them.

 

 

     The study's lead researcher says doctors need to be more aware that heart attacks during pregnancy differ from a typical heart attack in their causes and treatments.
