Cardiovascular disease (CVD) is currently the leading cause of death among Europeans and Americans. While many risk factors for CVD have been identified, their role in the etiology of CVD is not fully understood. One such risk factor is a family history of CVD. In addition to a positive family history, Type D personality has been established as an independent risk factor for CVD. The purpose of this study was to examine the hemodynamic reactivity to laboratory stress in young adults with a positive family history of stroke and/or Type D personality, and to look at its interaction. Thirty-nine healthy young adults completed two laboratory stressor tasks. Cardiovascular measures were recorded throughout the experiment. The results showed that there were no main effects of family history on cardiovascular reactivity. There was a significant effect of Type D personality on total peripheral resistance (TPR) during the speech recovery period, but not on systolic blood pressure (SBP), diastolic blood pressure (DBP) or cardiac output (CO). The interaction effect between family history and NA was significant. Lack of significant main effect of family history on reactivity might be due to too few participants.
