Active clinical trials for "Hypertension"

The goal of this study is to demonstrate the use of osteopathic manipulative therapy (OMT) in the effective management of hypertension. The investigators hypothesize that by addressing/correcting somatic dysfunctions with OMT, the sympathetic overdrive that could be the root cause of the elevation in blood pressure will be downregulated. If this is the case, then an effective therapy for hypertension could indeed be regular OMT treatment. This could also result in the avoidance of potentially harmful antihypertensive medications which comprise a majority of the current therapeutic strategy in the treatment of hypertension (along with lifestyle modification). A third implication of the results of this project could be a reduction in the progression of this disease. Under the current standard of care, a majority of hypertensive patients only experience a worsening of the disease over time under the current therapeutic guidelines.

The objective of the study is to investigate effects of inorganic sodium nitrite on the cardiometabolic and hormonal disturbances observed in a targeted population of overweight/obese adults with metabolic syndrome and hypertension, at risk for insulin resistance and endothelial dysfunction.

Activity-related dyspnoea appears to be the earliest and the most frequent complaint for which patients with PAH seek medical attention. This symptom progresses relentlessly with time leading invariably to avoidance of activity with consequent skeletal muscle deconditioning and an impoverished quality of life. Unfortunately, effective management of this disabling symptom awaits a better understanding of its underlying physiology. Our team has recently showed that PAH patients may exhibit reduced expiratory flows at low lung volumes at spirometry (namely instantaneous forced expiratory flows measured after 50% and 75% of the FVC has been exhaled [FEF50% and FEF75%] lower than predicted), despite a preserved forced expiratory volume in 1 second/forced vital capacity ratio (FEV1/FVC) . Several studies have shown that such a finding ("small airway disease") could be common in certain PAH cohorts, have either related it to incidental descriptions of airway wall thickening with lymphocytic infiltration in PAH or proposed several other speculative explanatory mechanisms, either biological or mechanical. Whatever its cause, reduced expiratory flows at low lung volumes imply that the operating tidal volume (VT) range becomes closer than normally to residual volume (RV) mostly through an increase in RV (elevated residual volume/total lung capacity ratio, RV/TLC). The reduced difference between forced and tidal expiratory flows promotes dynamic lung hyperinflation [i.e., a progressive increase in end-expiratory lung volume (EELV)] under conditions of increased ventilatory demand. Dynamic lung hyperinflation (DH) is well known to have serious sensory consequences, i.e., increase in dyspnoea intensity, as clearly shown in patients with chronic obstructive pulmonary disease and chronic heart failure. The aim of this study is to evaluate whether administration of inhaled BDs (β2-agonist and/or anticholinergic), as add-ons to vasodilators, would be beneficial to PAH patients by reducing and/or delaying the rate of onset of DH, thus ameliorating the exertional symptoms in patients with stable PAH undergoing high-intensity constant work-rate (CWR) cycle endurance test. This is a randomised double-blind placebo-controlled crossover study. Design: 5 visits; V1: screening, familiarization, incremental cardiopulmonary exercise testing (CPET); V2: constant work-rate (CWR-CPET); V3, V4 and V5: CWR-CPET after intervention, in a random order: Placebo (P), Ipratropium Bromide (IB), Ipratropium Bromide + Salbutamol (IB+SALB).

Chlorthalidone will result in improved endothelial function compared to hydrochlorothiazide as measured by flow mediated vasodilatation.

This 3-armed randomized controlled trial aims to evaluate the effectiveness of The Microclinic Behavioral Health Program in improving obesity and diabetes risk factors through a behavioral intervention program structured to enhance and promote social-network interactions and social support. The full version of the Microclinic Behavioral Health Program (Full MCP) with program-activated social-network interactions-with shared access to diabetes education, technology, and group support to promote weight and metabolic control through diet, exercise, medication adherence, and blood pressure management. Participants play a role in the collective effort to combat diabetes and solidifying self-management behavioral skills through peer-monitoring and encouragement of lifestyle behaviors. The study may yield valuable information on the impact of social support and social network interactions for enhancing body weight and blood sugar control. We compare the full MCP intervention, to a basic MCP intervention with more limited classroom interaction, and to an parallel monitoring control arm. This Microclinic Behavioral Health Program was established in collaboration with the Royal Health Awareness Society (RHAS) and the Jordanian Ministry of Health (MoH).

This study will compare two arms in a randomized clinical trial of cardiovascular risk prevention in women with a history of preeclampsia. The first arm will provide postpartum patients and their clinicians with the American Heart Association's (AHA) Class I Lifestyle Recommendations for women with a history of preeclampsia. The second arm will additionally receive access to a customized patient-informed online program with modules on how to achieve the AHA recommendations for diet, activity and weight management.

The Pamela Study is a clinical trial carried out during pregnancy to assess the potential effects of physical activity during pregnancy among previously inactive women. The trial is nested into a birth cohort of more than 4000 dyads (mother-child) and took place in Pelotas, Brazil.

The purpose of this study is to evaluate the effect of dexmedetomidine on hemodynamic responses during laryngoscopy and double lumen endotracheal intubation and assess the adverse effect related to complications of dexmedetomidine.

This study will investigate the safety and efficacy of Triple Combination Therapy with dorzolamide hydrochloride/brimonidine tartrate/timolol ophthalmic solution in patients with glaucoma or ocular hypertension who have elevated IOP on dorzolamide hydrochloride/timolol maleate combination therapy.

This randomized clinical trial examines if lowering and maintaining 24-hour ambulatory systolic blood pressure to <130 mmHg (intensive control) versus <145 mmHg (standard control) slows/halts the progression of deterioration of mobility and cognitive function linked to white-matter disease (also known as white-matter hyperintensity or WMH) in patients with normal or mildly impaired mobility and cognition in subjects with detectable cerebrovascular disease (>0.5% WMH fraction of intracranial contents). The study patients will be enrolled and randomized to one of two levels of ambulatory blood pressure control (intensive to achieve a goal 24-hour systolic blood pressure of < 130 mmHg or standard to achieve a goal 24-hour systolic blood pressure of < 145 mmHg) for a total of 36 months.
