The influence of gender and family history of cardiovascular diseases (CVDs) on the frequency of subjects with pressor (BP) and chronotropic (HR) hyperresponsiveness to stressor tests. The data in the left graphs are from 30 males and 12 females exhibiting hemodynamic hyperresponsiveness. The data in the right graphs are from 26 subjects exhibiting concurrent hemodynamic hyperresponsiveness and a family history of CVDs and from 18 subjects with hemodynamic hyperresponsiveness only. *p<0.05 and **p<0.01compared with female group or with no family history of CVDs group.
