Race, Parental History of Hypertension, and Patterns of Cardiovascular Reactivity in Women

摘要: This study examined the interaction of race and parental history hypertension on patterns cardiovascular responses among women. Two stressors were used that produce different reactivity: mental arithmetic, primarily a beta-adrenergic stimulus, cold face which evokes alpha-adrenergic (i.e. vascular) activity. Systolic diastolic blood pressure, heart rate, forearm flow, vascular resistance assessed before, during, after arithmetic stimulus. Both tasks produced expected adjustment, although no Black-White differences occurred during arithmetic. However, Black subjects did show slower recovery pressure following The stimulus significantly greater changes in systolic than White Parental not relate to reactivity. results provide limited support for idea females exhibit pressor response produces rather cardiac changes. These findings are discussed relation previous with males respect their implications role reactivity prevalence.
