Abstract: | The authors examined whether cardiovascular reactivity to and recovery from psychological challenge predict 3-year change in blood pressure (BP) among 216 initially normotensive, community-dwelling adults. Clinic BP assessments were conducted at baseline and follow-up. BP and heart rate (HR) readings were obtained before, during, and after 5 psychological tasks at baseline. Following adjustment for traditional predictors of BP and lifestyle factors, poorer systolic BP recovery across the tasks was associated with greater 3-year increases in clinic systolic and diastolic BP. Both diastolic BP recovery and HR recovery were also related to 3-year change in clinic BP, though cardiovascular reactivity measures were not. These findings suggest that the duration of stress-related cardiovascular responses may be important for predicting longitudinal changes in BP. |
