Full textINTRODUCTION: Des travaux antérieurs entrepris au laboratoire Rohlicek ont montré que l'hypoxie néonatale est associée à une élévation de la pression artérielle systolique chez les rats mâles âgés de deux mois. Dans le cadre de la présente étude, on demande si cette élévation persiste plus tard dans la maturité et si elle est également présente chez les femelles. On essaye en outre de déterminer si les hormones sexuelles ou des altérations dans le contrôle autonome jouent un rôle dans cette élévation. MÉTHODE: Des études ont été menées sur des rats adultes Sprague-Dawley des deux sexes. Un groupe expérimental a été élevé en hypoxie (FiO2 = 0,12) durant les dix premiers jours de vie et subséquemment en normaxie. Un second groupe a été élevé entièrement en normaxie. Un sous-ensemble de mâles et de femelles ont été gonadectomisés un mois avant la prise de mesures. À deux, trois et six mois, des rats étaient branchés à un transducteur de pression artérielle intravasculaire avec télémétrie pour surveillance de la pression de l'aorte abdominale. Une semaine plus tard, la pression artérielle a été mesurée durant 24 heures chez des rats ambulatoires et non contenus. RÉSULTATS: La pression systolique a été considérablement plus élevée chez des rats mâles en hypoxie à tout âge durant leur période active (nocturne) et également à 3 et 6 mois durant la période de repos (diurne) par comparaison aux rats du groupe témoin. L'ampleur de l'effet de l'hypoxie néonatale s'est accrue avec l'âge, bien que cette augmentation n'ait pas été statistiquement significative. Les femelles en hypoxie néonatale n'ont montré aucune différence dans la pression artérielle générale par comparaison aux femelles du groupe témoin. Tout comme la castration n'a pu empêcher l'apparition d'une pression artérielle élevée chez les mâles en hypoxie néonatale âgés de deux mois, l'ovariectomie de même n'a pu montrer une quelconque différence entre les femelles en hypoxie néonatale par opposition aux femelles du groupe témoin à l'âge de trois mois. Chez les rats mâles âgés de deux mois en hypoxie néonatale, la sensibilité du baroréflexe a été considérablement atrophiée durant leur période active (nocturne). CONCLUSION: Nos résultats indiquent que l'élévation de la pression artérielle chez les rats mâles adultes en hypoxie néonatale persiste plus tard dans la maturité. Cet effet semble être spécifique selon le sexe chez les animaux mâles. La découverte de la sensibilité du baroréflexe atrophiée à la suite de l'hypoxie néonatale à deux mois indique que le tonus autonome altéré, conjugué à une augmentation relative de l'activité sympathique, jouent un rôle dans l'élévation de la pression artérielle.

The primary aim of this dissertation was to evaluate the factors that contribute to the cardiorespiratory and vascular responses following exercise conditioning and microgravity deconditioning. The first study of this dissertation (Chapter 2) revealed that exercise training in the head down tilt posture, which places increases central blood volume compared to upright, results in cardiorespiratory adaptations in both upright and head down tilt postures which are not completely expressed with exercise training in the upright posture. These findings suggest that augmentation of the ventricular volume load during exercise training may result in adaptations that transfer across multiple body positions. In the second and third studies measurements of blood velocity and flow were performed via Doppler ultrasound. In Chapter 3 we observed that in the brachial and femoral arteries blood moves with a slightly blunted parabolic velocity profile that is very stable across a range of mean arterial pressures and downstream limb resistances. We concluded that these findings support the current calculations of shear rate based on the assumptions of laminar flow. With these assumptions confirmed, the investigation in Chapter 4 could be performed. We observed that acute exposure to a sustained antegrade shear rate, via unilateral forearm heating, increased measurements of flow-mediated dilation and the overall rate of adjustment for forearm blood flow and vascular conductance during dynamic handgrip exercise. These findings suggest that one potential stimulus for improvements in vascular function and health following exercise conditioning may be exposure to elevations in antegrade shear. Lastly in Chapter 5 we changed focus to the cardiorespiratory deconditioning following long-duration microgravity exposure. We retrospectively reviewed and analyzed previous investigations of microgravity deconditioning and demonstrated that the decrease in maximal O2 consumption ( O2max) occurs as a function of duration of exposure and that both convective and diffusive O2 transport pathways substantially contribute to this decline. In addition we reviewed the current literature and highlighted potential mechanisms, across several organ systems, which may contribute to this decline in O2max. Collectively, these studies revealed the breath of plasticity for cardiorespiratory adaptations to a variety of stressors.

Full textThe objective of this dissertation was to systematically investigate the hemodynamic response to exercise in heart failure with reduced ejection fraction (HFrEF) and healthy individuals of a similar age, with an emphasis on how the sympathetic nervous system (SNS) may contribute to the dysregulation of the cardiovascular system in this cohort. The first study aimed to determine how varying levels of metaboreceptor activation alters the mean arterial pressure (MAP) response as well as the degree in which cardiac output (CO) and systemic vascular conductance (SVC) contribute to the metaboreflex-induced increase in MAP. We observed similar increases in MAP induced by metaboreceptor activation in both groups; however, this response was driven primarily by increases in CO in the control group and reductions in SVC in the HFrEF group. These data suggest a preserved role of the metaboreflex-induced increase in MAP in HFrEF, but suggest that this response is governed by the peripheral circulation in this cohort, a maladaptation that may exacerbate systolic dysfunction through an increase in afterload. The second study of this dissertation was focused on investigating the peripheral vasodilatory and hyperemic response to exercise in isolation of central hemodynamic limitations in both the upper and lower limbs. This study documented an impaired hyperemic response to both static-intermittent handgrip exercise as well as dynamic single-leg knee-extensor exercise in HFrEF patients - impairments primarily attributed to vasodilatory dysfunction, as the increase in MAP induced by these exercise modalities was preserved compared to healthy individuals. Together, these findings have identified a significant attenuation of the exercise-induced hyperemic response during both upper and lower limb exercise, implicating maladaptions in the peripheral hemodynamic response to exercise as a potential contributor limiting exercise capacity in this patient group. The third study sought to address the contribution of the alpha-adrenergic receptor pathway in the regulation of blood flow to exercising skeletal muscle in HFrEF patients. At rest, alpha-1-adrenergic receptor vasoconstriction induced by local intra-arterial infusion of phenylephrine (PE) was reduced in HFrEF compared to control subjects. During exercise, the vasoconstrictor responsiveness to PE was significantly attenuated in the control group and preserved in HFrEF patients compared to rest. Additionally, nonspecific alpha-adrenergic receptor antagonism induced by local intra-arterial infusion of phentolamine increased blood flow to a greater degree in HFrEF compared to the control subjects, both at rest and during exercise. Together, these findings demonstrate a marked contribution of alpha-adrenergic receptor restraint of leg blood flow in HFrEF patients during exercise. Collectively, these three studies have provided new insight into the role the SNS and peripheral hemodynamics play in the maladaptive cardiovascular response to exercise displayed in patients with HFrEF, further implicating the peripheral expression of SNS activity as a primary contributor to impaired exercise capacity in this patient group.
