Parental history of hypertension and cardiovascular responses to behavioral stress in young black women.

Published

Journal Article

Beta-adrenergic sympathetic nervous system (SNS) hyperresponsivity to behavioral stress may play a role in the onset of sustained high blood pressure--particularly in persons with a parental history of hypertension. Although hypertension is extremely prevalent among blacks, the association between parental history of hypertension and cardiovascular hyperresponsivity has not been explored in this group. The present study examined the influence of parental history of hypertension on cardiovascular stress reactivity in a group of young black females. Contrary to previous findings with whites, black subjects with a parental history of hypertension exhibited significantly smaller systolic blood pressure and forearm blood flow increases, and moderately smaller diastolic blood pressure increases to the task. Parental history subjects also exhibited slower heart rates throughout each experimental condition. The results suggest that blacks at risk from hypertension may not exhibit the beta-adrenergic hyperresponsivity to behavioral stress observed in whites. These results may suggest that beta-adrenergically mediated hyperresponsivity may be less involved in the development of hypertension among blacks.
