Stress-induced cardiovascular reactivity among African American smokers.
OBJECTIVE
To test for differences in stress-induced cardiovascular functioning among hypertensive and normotensive African American (AA) smokers.


METHODS
Participants (n = 35) were exposed to both stress and neutral mood inductions.


RESULTS
Repeated measures analyses of covariance produced a significant group x mood condition interaction for systolic blood pressure (P = .048), but not for diastolic blood pressure (P > .05). The most notable finding was that AA hypertensive smokers showed selectively greater elevations in their systolic responses compared with normotensive controls following the laboratory-induced stressor.


CONCLUSIONS
Implications to an elevated risk of future cardiovascular disease among AA hypertensive smokers are discussed.
