 Medicine provides another example of the limited responsiveness of a field to feminist critique. Heart disease in women was often not recognized or understood primarily because the research had focused on men. Although more recent research has included women, as late as 2017 research on medical practice indicated that women still are not screened for heart disease as regularly as men during routine health examinations. In addition, 45% of women in a nationwide survey were unaware that heart disease is the number one cause of fatality for women (Bairey Merz et al. 2017). Since 1993 the National Institutes of Health (NIH) has required that women (and minorities) be included in research projects that are NIH funded (see  Other Internet Resources).  However, there are problems recruiting and retaining sufficient numbers of women for such research as evidenced by the literature review on the topic at the NIH website. The requirement does not, in itself, correct gender inequities in medical research which tend to be more systematic and structural.
