Background
Different demographic subgroups may have different prevalence, diagnosis, disease progression and treatment outcomes for some diseases. Although cardiovascular disease (CVD) is the number one killer of women, women have historically been underrepresented in cardiovascular clinical trials (CVTs). To accurately assess sex differences in the safety and efficacy of medical devices, it is necessary to have representation of both sexes in clinical trials to allow for sex-specific analysis. The purpose of this study was to assess the participation of women and ethnic subgroups in CVTs submitted in support of medical device premarket applications (PMAs) approved by the US FDA from 2005 to 2009.
Methods
All CVTs in approved PMAs approved from 2005 to 2009 were reviewed. Descriptive analyses of the study participants’ ethnicity and sex were tabulated. Demographic data from PMAs were analyzed in 12-month intervals to detect any notable trends in the rate of women’s and ethic subgroup’s participation.
