Cardiovagal baroreflex sensitivity was lower in HT (6.8±1.7 msec/mniHg) versus NT (16.4±2.2 msec/mmHg). (uwo.ca)
The dissociation between the training induced changes in resting MSNA, lack of change in baroreflex sensitivity and the change in blood pressure, suggests that MSNA is not a main cause of the blood pressure reduction with exercise training in un-medicated middle-aged/older men. (ku.dk)
Beyond the age of sixty years, baroreflex sensitivity is independently related to the level of systolic blood pressure but not to age. (le.ac.uk)
In conclusion, hypertension in the elderly is associated with reduced baroreflex sensitivity, an impaired blood pressure response to orthostasis and increased resistance artery media:lumen ratio, but no differences in endothelial or vascular smooth muscle function. (le.ac.uk)
Methods and Results - In a double-blind randomized study, 25 healthy subjects with a positive response to either carotid sinus massage (CSM) or lower body negative pressure (LBNP) received Paxil (20 mg/d) or placebo for 6 weeks, Arterial baroreflex sensitivity (BRS), muscle sympathetic nerve activity (SNA), baroreflex control of SNA, blood pressure, and heart rate responses to CSM and LBNP were measured at baseline and at 6 weeks. (elsevierpure.com)
baroreflex sensitivity in ms/mm Hg (BRS) and baroreflex sensitivity in Hz/mm Hg (BRSf), were determined by spectral analysis, in 20 normotensive volunteers age of 27+/-6 years (mean+/-S.D.) who served as their own control. (who.int)
In contrast with Ang II, Ang-(1-7) improves baroreflex sensitivity and plays an inhibitory role in hypothalamic noradrenergic neurotransmission. (eurekaselect.com)
Additionally, cerebral blood flow velocity (Transcranial Doppler) and blood pressure (Finapres) were measured in rest, and during sit-to-stand and CO2 challenges to assess baroreflex sensitivity, cerebral autoregulation, and cerebral vasomotor reactivity. (edu.au)
Results: No short-term differences were observed in cognitive performance, cerebral blood flow velocity, baroreflex sensitivity, cerebral autoregulation, or cerebral vasomotor reactivity across time, or between conditions. (edu.au)
Sympathetic7
In conclusion, skin blood flow can be a useful tool to evaluate sympathetic activity and combination therapy with calcium antagonists and angiotensin II receptor blockers were the most useful therapy for suppressing the hemodynamic response to mental stress. (scirp.org)
Arterial baroreflexes may regulate resistance vessels supplying glucose to skeletal muscle by modulating efferent sympathetic nervous system activity. (shengsci.com)
Baroreflex-mediated changes in sympathetic vasomotor tone may have a limited acute effect on muscle glucose metabolism in patients with treatment-resistant hypertension. (shengsci.com)
This study tested the hypothesis that training reduces resting sympathetic activity and improves baroreflex control in both hypertensive and normotensive men but reduces blood pressure only in hypertensive men. (ku.dk)
The overarching hypothesis is that resting MSNA will be negatively associated with sympathetic-BP transduction due to methodological limitations of the signal-averaging technique, baroreflex mechanisms governing MSNA burst occurrence, and α-adrenoreceptor responsiveness. (uoguelph.ca)
Conclusions: The negative association between sympathetic outflow and sympathetic-BP transduction was largely governed by the proportion of MSNA bursts firing above the mean BP set-point, highlighting baroreflex mechanisms contributing to the reductions in sympathetic-BP transduction in individuals with elevated sympathetic outflow. (uoguelph.ca)
In conclusion, SNP had no effect on the cardiac-vagal limb of the baroreflex in humans but caused a substantial reduction in BP low-frequency power consistent with a decreased baroreflex/sympathetic control of peripheral resistance. (ox.ac.uk)
Systolic blood pr2
BEI was quantified as the ratio of the number of baroreflex-driven ramps relative to all systolic blood pressure ramps. (wku.edu)
In conclusion, wheel exercise can modulate sleep-related cardiovascular dysfunction and the flattening of circadian rhythm, preventing the progression of hypertension, which reduces the incidence of cardiovascular diseases. (nature.com)
For diagnosing OHT, the search should focus on identifying surgically correctable causes of hypertension or ruling out baroreflex failure based on the previous studies. (bpincontrol.in)

The major effects of sepsis on the cardiovascular system can be summarized as follows: a systolic and diastolic cardiac dysfunction, an increased heart rate despite an overall reduction in autonomic modulation of heart activity and an impairment in the baroreflex sensitivity. (polimi.it)
Since SV recovered to baseline levels during the "pull" phase (HUT1-3), with TPR and forearm vascular resistance remaining depressed, baroreflex-mediated peripheral vascular control is delayed. (unboundmedicine.com)
In conclusion, LL disrupted the peripheral circadian rhythms more severely in liver than in WAT. (researchgate.net)
