There is increasing evidence that diurnal blood pressure (BP) variation, in addition to high BP per se, is related to target organ damage and the incidence of cardiovascular events. However, the determinants of diurnal BP variation are not adequately understood. This paper tests the hypothesis that cardiovascular reactivity to acute stress and/or delayed recovery predicts greater diurnal BP var...

OBJECTIVE In recent analyses of data from a large community sample, negative cross-sectional and prospective associations between cardiac stress reactivity and obesity were observed. The present study reexamined the association between cardiovascular reactivity and adiposity in the Dutch Famine Birth Cohort, with the additional aim of examining the association between cortisol reactivity and ad...

Cardiovascular disorders continue to constitute major causes of morbidity and mortality in diabetic patients. In this study, the effect of chronic administration of sesame (Sesamum indicum L) seed feeding was studied on aortic reactivity of streptozotocin (STZ)-diabetic rats. Male diabetic rats received sesame seed-mixed food at weight ratios of 3% and 6% for 7 weeks, one week after diabetes in...

The Relationship of Regional Cerebrovascular CO, Reactivity to Blood Pressure and Regional Resting Flow • Cerebrovascular CO 2 reactivity (the change in cerebral blood flow per mm Hg change in Pa c02) is shown to be directly related to resting flow and inversely related to blood pressure for regional as well as for mean CBF data. Both regional and mean CO 2 reactivity therefore are proportional...

ranged from 1.7% (Ghana) to 45.3% (Hong Kong). The association between current wheeze and skin-prick test reactivity was stronger in affluent countries (odds ratio: 4.0 [95% confidence interval: 3.5–4.6]) than nonaffluent countries (odds ratio: 2.2 [95% confidence interval: 1.5–3.3]). The population attributable fraction (PAF), or fraction of current wheeze attributable to skin-prick test react...

Background & Aims: Considering the higher incidence of cardiovascular disorders in diabetes mellitus and some evidence on antioxidant and antidiabetic potential of Tribulus terrestris (TT), this study was conducted to evaluate the beneficial effect of 6-week oral administration of TT on contractile reactivity of isolated thoracic aorta in diabetic rats. Methods: Female Wistar rats were divided ...

Regional cerebral blood flow (CBF), oxygen utilisation, fractional oxygen extraction (OER) and cerebral blood volume (CBV) were measured by positron emission tomography (PET) in 21 patients with occlusive carotid artery disease. In the same patients, measurements of cerebral CO2 reactivity were performed using the intravenous xenon-133 technique. A significant correlation was found in symptomat...
