Why doctors still misunderstand heart disease in women

Heart disease is currently the number-one cause of death among women in the U.S., killing more than all cancers combined. While men are more likely to be diagnosed with heart disease, according to the American Heart Association, women still made up slightly more than half of all its fatalities in 2011, the most recent year for which data was available. Women are also more likely than men to die in the year following a heart attack. In part, these disparities can be traced back to a bias older than modern medicine itself.
