How many women would survive heart attacks with female doctors?

An Olin Business School study by Seth Carnahan of nearly 582,000 heart attack cases over 19 years showed female patients had a significantly higher survival rate when a woman treated them in the ER. In fact, in the researchers’ sample, 1,500 fewer women would have died—women who were treated by male doctors—if their survival rate was the same as women treated by female physicians.
