Gender affects sympathetic and hemodynamic response to postural stress.
We tested the hypothesis that differences in sympathetic reflex responses to head-up tilt (HUT) between males (n = 9) and females (n = 8) were associated with decrements in postural vasomotor responses in women. Muscle sympathetic nerve activity (MSNA; microneurography), heart rate, stroke volume (SV; Doppler), and blood pressure (Finapres) were measured during a progressive HUT protocol (5 min...
متن کاملRole of sympathetic responses on the hemodynamic consequences of rapid changes in posture in humans.
Tolerance to +G(z) gravitational stress is reduced when +G(z) stress is preceded by exposure to hypogravity (fractional, 0, or negative G(z)). For example, there is an exaggerated fall in eye-level arterial pressure (ELAP) early on during +G(z) stress (head-up tilt; HUT) when this stress is immediately preceded by -G(z) stress (head-down tilt; HDT), termed the "push-pull effect." The aim of the...
متن کاملVentilatory, hemodynamic, sympathetic nervous system, and vascular reactivity changes after recurrent nocturnal sustained hypoxia in humans.
Recurrent and intermittent nocturnal hypoxia is characteristic of several diseases including chronic obstructive pulmonary disease, congestive heart failure, obesity-hypoventilation syndrome, and obstructive sleep apnea. The contribution of hypoxia to cardiovascular morbidity and mortality in these disease states is unclear, however. To investigate the impact of recurrent nocturnal hypoxia on h...
متن کاملEvaluation of Mexiletine Effect on Bispectral Index Changes and Hemodynamic Responses to Endotracheal Intubation and During General Anesthesia
Background &Objective: Plaryngoscopy and tracheal intubation increase not only blood pressure and heart rate but also Bispectral Index (BIS) of the patients. In this study, hemodynamic and BIS changes were surveyed after tracheal intubation and during general anesthesia followed by mexiletine prescription . Materials & Methods: In this study, 50 patients aged between 20 and 60 who were ca...
متن کاملCorrection to: Sympathetic Neural and Hemodynamic Responses During Cold Pressor Test in Elderly Blacks and Whites.
In the article by Okada et al, “Sympathetic Neural and Hemodynamic Responses During Cold Pressor Test in Elderly Blacks and Whites,” which published online on March 28, 2016, and appeared in the May 2016 issue of the journal (Hypertension. 2016;67:951–958. DOI: 10.1161/ HYPERTENSIONAHA.115.06700), a correction is needed. Figures 2 and 3 that had missing text due to a publication error have been...
