Abstract
This study reports a meta-analysis comparing groups with high blood pressure to those with normal blood pressure in terms of increases from baseline in systolic blood pressure, diastolic blood pressure, and heart rate while participants performed challenging or stressful tasks. This meta-analysis consists of information from published studies that were analyzed for differences between the two groups. The differences in participant reactions to challenging task conditions were measured by the mean changes in systolic blood pressure, diastolic blood pressure, and heart rate. Mean change scores were calculated by subtracting the mean baselines for a physiological measure from the mean value for a physiological measure recorded in a particular stressor condition. A series of regression analyses were conducted predicting mean change scores in heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) for high blood pressure groups from the mean change scores for the normal blood pressure groups. For all three measures of cardiovascular function (i.e., HR, SBP, and DBP), slopes were found to be significantly different from 1.0 and y-intercepts were significantly different from zero. This pattern indicates that differences in cardiovascular reactivity between hypertensive and normotensive groups were largest in situations with lower stress levels.
