Cardiovascular reactivity of patients with essential and renal hypertension in an emotion-triggering interview

Abstract

Blood pressure reactivity to mental stress in hypertensives is much higher than in normotensives. The authors' aim in this study was to examine whether different cardiovascular responses can be induced by various stimuli in hypertensive subgroups. The authors matched 10 essential hypertensives (EHs), 10 renal hypertensives (RHs), and 10 normotensives (Ns) according to age and gender examined them during an emotion-stimulating interview, and measured blood pressure (BP) and heart rate (HR) during the phases of the interview. They observed differences in BP reactivity between EHs/RHs and Ns under some stimuli but not between EHs and RHs, as well as a marked difference in the product of systolic BP (SBP) and HR between both hypertensive groups in the anger/rage phase (p = .028) and the baseline 2 (p = .02). This shows a higher cardiovascular activation under mental stress and a lower recovery in EHs and more sensitivity to perturbation or higher central tension compared with RHs.
