Active clinical trials for "Hypertension"

Open-label extension of RIN-PH-302.

To study the effect of acute pulmonary vasodilatation on cerebral tissue oxygenation (CTO) and cerebral blood flow (CBF) as indicator for cerebrovascular autoregulation in comparison to the effects of supplemental oxygen, decreased carbon dioxide by hyperventilation and exercise in patients with pulmonary hypertension (PH) undergoing clinically indicated right heart catheterisation (RHC). Oxygenation and hemodynamic parameters will be assessed during RHC according to standard procedures. Non-invasive near infrared spectroscopy (NIRS) and a nasal canula will be additionally applied to measure CTO, CBF and endtidal CO2 (EtCO2). All parameters will be obtained at rest breathing room air, during an oxygen challenge, during standardized hyperventilation, under vasodilatation testing and during exercise in random, single-blinded sequences (except for exercise and hyperventilation). Pulmonary, systemic and cerebral oxygenation parameters and hemodynamics will be correlated with each other and functional class, quality of life, exercise and cognitive assessments at the time of the RHC and after three month.

The purpose of this study is to compare the effects of 12 weeks of structured classes of either iyengar yoga (IY) or an enhanced usual care intervention on blood pressure, heart rate variability, quality of life measures, lipid measures, and safety in patients with high-normal to stage I hypertension.

In patients with hypertension who undergo elective PCI, the effects of long-term administration of Calblock (azelnidipine) on plaque volume will be determined quantitatively by 3D-IVUS and compared with those of amlodipine besilate (Norvasc or Amlodin).

Compare the reduction in Framingham's predicted 10-year risk of a coronary event (6) in patients with hypertension and at least three other cardiovascular risk factors (including diabetic patients) seen in private practice and randomized to either Caduet or usual care.

The primary objective of this proposal is to demonstrate that ABPM can be used to improve study design for interventional trials in children with hypertension.

While patient held guidelines for the management of chronic diseases have been employed in some countries. There is little evidence of their effectiveness in improving patient outcomes. We hypothesised that a patient held guideline on the management of hypertension combined with a specific exhortation to patients to challenge their medical care where the guidelines did not appear to have been applied would improve blood pressure control, lower average blood pressure, lower average cholesterol, increase the appropriate use of statins and aspirin, and have no impact on patient anxiety. Patients were randomised to the guideline or to standard hypertension information. Measures of anxiety were taken at baseline 2 weeks and one year, blood pressure and cholesterol was measured at one year and case notes examined to determine appropriate statin and aspirin usage.

To develop a culturally tailored intervention intended to promote adherence to nutrition and physical activity regimens designed to result in weight loss for African American women.

To evaluate the long-term effect of reduction of alcohol intake on blood pressure in moderate but non-dependent drinkers with mild hypertension or high normal blood pressure.

To test the feasibility and the efficacy of nutritional interventions in the primary prevention of hypertension in individuals predisposed to the development of hypertension; specifically, to test the hypothesis that reduction of weight and/or decreased sodium intake in obese individuals, or decreased sodium intake with or without increased potassium intake (in men and women, regardless of weight) would prevent the elevation of blood pressure and the incidence of hypertension.
