Active clinical trials for "Hypertension"

Hypertension is a public health concern and affects nearly a third of the French population. It can be complicated by visceral impact (including brain, heart and kidney complications) as well as on vessels especially large arteries, responsible for arterial stiffening. There are close interactions between heart and kidneys, as well as between large arteries and micro-vessels. These relationships also involve the water and salt balance and its regulatory mechanisms. Urinary concentration abilities are closely linked to the renal medullary blood flow, which in itself depends on the integrity of renal micro vessels, thus influencing the water and salt balance. Few previous studies evaluated the interconnections between renal urinary concentration abilities and blood pressure. A previous-one reported a positive relation between pulse pressure and urinary concentration in men, suggesting that subjects with higher urinary osmolarity could present a higher cardiovascular risk. Carotid-femoral pulse wave velocity represents the gold standard for non-invasive arterial stiffness assessment and constitutes an arteriosclerosis infra-clinical marker recommended by the European Society of Cardiology- European Society of Hypertension. It is considered as an independent predictor for global and cardiovascular mortality, coronary heart disease and fatal stroke among patients with hypertension, diabetes or end stage kidney disease. The purpose of this study is to evaluate the relations between fasting urinary osmolarity and arterial stiffness assessed by carotid-femoral pulse wave velocity (CF-PWV) among patients with hypertension.

The purpose of this research study is to use a test called impedance cardiography (ICG) to provide more information about how to improve the control of blood pressure. Participants will be given this test so investigators can get more information about what is going on inside the heart and blood vessels that is contributing to high blood pressure. ICG is a lot like an EKG (electrocardiogram) in that it uses electrodes and a computer to make a report. Participants will lie down on the exam table and two electrodes go on the right ankle and two electrodes go on the left wrist. The process takes about 5 minutes and is painless and not invasive.

This is a Randomized, open-label, single-dose, 2-treatment, 2-period, 2-sequence crossover design.

The development of disease-targeted medication for the treatment of pulmonary arterial hypertension (PAH) has significantly improved within the last years, leading to the development of 10 approved agents. Combination treatment with Endothelin-Receptor-Antagonists (ERA) and Phosphodiesterase-Type-5-Inibitors (PDE-5-Inhibitor) has become increasingly important for the treatment of PAH. In a recent press release, the results of the AMBITION study reported that an upfront combination treatment immediately after diagnosis leads to a delayed disease progression [4]. Thus, the question if there is a clinically relevant pharmaco-dynamic drug-drug interaction is of rising interest.

Written surveys of patients with high blood pressure are designed to determine how they would likely decide if, in addition to taking medication, they had another option to treat their hypertension. The alternative treatment option is renal sympathetic denervation using catheter ablation. This new treatment method is not yet used in the standard care. Currently, studies are being conducted in specific centers to demonstrate the efficacy of this treatment. Questionnaires are used to determine the preference of patients for one or the other option of hypertension treatment. So far, there are no findings.

The purpose of this survey is to evaluate the safety and efficacy of long-term use of azilsartan/amlodipine combination tablets Low Dose (LD) & High Dose (HD) (Zacras Combination Tablets LD & HD) in hypertensive patients in daily medical practice.

The Intensive Dietary Counselling (IDC) intervention is a prevention and health promotion activity. It is being implemented by the Andalusian Health Service to reinforce basic intervention advice on healthy diet and exercise. The IDC intervention is aimed at the prevention of diseases of the heart and blood vessels (e.g. heart failure, heart attack and stroke). The main objective of the present study is to assess adherence to the IDC intervention and, consequently, its effectiveness on the prevention of the above mentioned diseases.

Background: High blood pressure is a common complication observed in cancer patients prescribed anti-VEGF drugs. Increased blood pressure increases the risk of heart attacks and strokes, thus adversely affecting survival and quality of life in this patient group. However, little is known about the mechanisms leading to high blood pressure with anti-VEGF drugs. As a result, the management of anti-VEGF drug-induced hypertension is largely empirical. A better knowledge of effects of specific blood pressure lowering drugs, i.e. antihypertensives, on anti-VEGF drug-induced hypertension would optimize therapeutic management and reduce the risk associated with hypertension and proteinuria in patients with cancer. Methods: Datasets of two completed GSK clinical trials using the anti-VEGF drug pazopanib, i.e. VEG108844 and VEG105192, will be accessed to 1) determine the way blood pressure changes over time after commencing anti-VEGF treatment; 2) identify whether there are any relationships between pre-study and baseline blood pressure values, treatment with specific antihypertensive drugs, and changes in blood pressure after commencing anti-VEGF treatment; and 3) identify whether specific antihypertensive drugs and drug combinations, prescribed either before or after commencing anti-VEGF treatment, lead to a better blood pressure control and prevent proteinuria during anti-VEGF treatment. Specific statistical analyses will be conducted to assess and identify associations and will account for other patient's characteristics and repeated observations over time. The investigators plan to conduct this study over 6 months. Studies VEG108844 and VEG105192 have been selected as they investigate the same anti-VEGF drug, pazopanib, in a homogeneous group, i.e. patients with renal cancer. At the same time, inclusion of a placebo arm as well as a treatment arm with a different anti-VEGF drug, sunitimib, will allow initial comparisons across different groups. The results deriving from this study will provide important knowledge on 1) patterns of blood pressure changes with anti-VEGF drugs and 2) whether specific antihypertensive drugs or drug classes might be better than others in preventing and managing anti-VEGF induced hypertension and proteinuria.

Study to confirm the safety profile of telmisartan (benefit-risk ratio) under normal conditions of use after market launch and to supplement the present data on the safety of telmisartan. Furthermore to assess effectiveness of a single dose of telmisartan per day to control blood pressure for 24 hours, especially during the last few hours of the dosage interval. Additionally to evaluate compliance with treatment, as an indirect measurement, and to confirm the efficacy and possible risks associated with treatment.

The ASSERT-III study aims to determine the incidence of sub-clinical (silent) atrial fibrillation (AF) among elderly patients with hypertension and at least one other risk factor for AF. This will be accomplished by monitoring with a wireless external loop monitor for 30 to 60 days.
