Active clinical trials for "Hypertension"

This study is a retrospective chart review to assess the tolerability and efficacy of treatment with Simbrinza™ used for patients with Open-Angle Glaucoma or Ocular Hypertension.

Elderly people usually have systemic diseases and take medications that can cause dry mouth. The purpose of this study is to determine whether continuous use of edible, gel-based artificial saliva in geriatric population with dry mouth problems will reduce signs and symptoms of dry mouth and improve quality of patients' saliva.

The known correlation between benign prostatic hypertrophy (BPH) and hypertension could be explained by 3 theoretical pathway models. Whether hypertension causes BPH, BPH causes hypertension or the two are caused by a common factor is currently unknown. In this study it will be investigated whether hypertension is due to the direct effects of infravesical obstruction to urinary outflow in patients with benign prostatic hyperplasia. The approach will be blood pressure measurement in patients who will have a resection of the prostate.

To describe the effectiveness of angiotensin-converting enzyme inhibitor and non-dihydropyridine calcium channel blocker single pill combination on systolic blood pressure (SBP) lowering in hypertensive patients with elevated heart rate and type 2 diabetes

Assess Fetal Mortality and Malformations in Women treated with antihypertensive medication during preganancy. Mother - Child pairs will be analysed in a cohort selected from the UK in the CPRD database. Years covered are 1997 to 2014. Aim is to assess the risk of Antihypertensive treatment in women.

The overall goal of this study is to evaluate agreement between cardiac MR parameters and well-established clinical and catheterization parameters of poor prognosis in patients with pulmonary hypertension. The identification of noninvasive cardiac MR techniques to evaluate myocardial disease in patients with pulmonary hypertension would be beneficial to society due to the potential to replace serial invasive cardiac catheterization procedures with a noninvasive imaging test.

In a randomized, sham-controlled trial the investigators will test whether supplemental oxygen given during cardiopulmonary exercise testing will improve exercise performance and physiological parameters in patients with pulmonary arterial or chronic thromboembolic pulmonary hypertension.

Background: In patients with cirrhosis on secondary prevention of variceal rebleeding with non-selective beta-blockers (NSBBs), the risk of rebleeding and death is markedly higher in those failing to achieve a good hemodynamic response (HVPG reduction ≥20% of baseline values or ≤12mmHg). However a substantial proportion of non-responders will never rebleed, thus appearing protected by NSBBs although non-detected by HVPG response. This low sensitivity hampers risk stratification and diminishes the cost-effectiveness of assessing the hemodynamic response to NSBBs. This is particularly relevant in prevention of rebleeding since in this scenario the risk of rebleeding and of other portal hypertension related complications is very high, which calls for early institution of effective therapy. Baseline HVPG bears prognostic significance with regards to risk of developing varices, decompensation, hepatocellular carcinoma and death1,2,7,8,18-27. However, no studies have investigated whether adding data from baseline HVPG may improve the sensitivity of the criteria defining a good or poor hemodynamic response. Hypothesis: Adding data from baseline HVPG may improve the sensitivity of the criteria defining a good or poor hemodynamic response. Objective: Exploring the prognostic value of basal HVPG that better discriminate those non-responders who do not re-bleed under prophylactic treatment with NSBBs. Methods: Observational cohort study. Training set: patients from two longitudinal studies conducted at the Hepatic Hemodynamic laboratory of the Hospital Clínic of Barcelona to assess the prognostic value of HVPG changes during continuous therapy with NSBBs for preventing variceal rebleeding. Validation set for chronic hemodynamic response: patients from two longitudinal studies conducted at the Hepatic Hemodynamic laboratory of the Hospital de Sant Pau of Barcelona to assess the prognostic value of HVPG changes during continuous therapy with NSBBs for preventing variceal rebleeding; a third cohort composed of patients undergoing acute hemodynamic response to intravenous propranolol will be studied. All patients received a preplanned follow-up in the outpatient clinic at 1, 3, and 6 months, and every 6 months thereafter in the original studies. End-point: bleeding from portal hypertensive sources (esophago-gastric varices or portal hypertensive gastropathy) (defined according to Baveno criteria 32), death or liver transplantation. Ethical aspects: All patients have given their written informed consent to use their data in the original studies.

The purpose of this study is to determine the effect of repeated renal denervation in non-responding patients with severe hypertension. Therefore ultrasound technique will be used.

The study will evaluate patients diagnosed with primary open angle glaucoma or ocular hypertension who are switched to Lumigan® UD monotherapy for medical reasons in accordance with physician standard clinical practice. All treatment decisions lie with the physician.
