Active clinical trials for "Hypertension"

The purpose of this study is to assess the safety of ranolazine in people with pulmonary arterial hypertension (PAH) and who are receiving 1 or more background PAH therapies: ambrisentan, sildenafil,tadalafil, epoprostenol, treprostinil (IV, SC, inhaled), or iloprost. The primary objective is: To estimate the effect of ranolazine administration on acute hemodynamics. To assess safety of ranolazine acutely over 6 hrs in the catheterization lab and after 12 weeks of therapy To assess changes in right ventricular function after 12 weeks of therapy.

The purpose of this study is to Evaluate the Antihypertensive efficacy of Fimasartan 30 mg during 24 hours in Patients with Mild to Moderate Essential Hypertension

Individuals in Appalachian Kentucky are vulnerable to cardiovascular disease (CVD) by virtue of having high rates of multiple CVD risk factors. There is a critical need to develop and test CVD risk reducing interventions that are appropriate and effective in Appalachia. In the absence of such interventions, the dramatic CVD disparities seen in this area will continue to rise. Lifestyle interventions reduce CVD risk by 44%. The investigators and others have demonstrated that lifestyle change is most effective when patients are given the tools to engage in effective self-care, and that interventions individualized to patients' specific needs and barriers are more effective than interventions that are not. The central hypothesis is that to be successful in Appalachia, CVD risk reducing interventions must focus on patient-centered lifestyle change that increase individuals' abilities to engage in self-care, must be culturally appropriate, and must have components that overcome barriers faced by individuals living in Appalachia. The investigators propose a randomized, controlled comparative effectiveness trial with 300 individuals from Appalachian Kentucky who do not have a primary care provider and who are at risk for CVD by virtue of having two or more modifiable CVD risk factors. The investigators will compare (1) a patient-centered, culturally appropriate, self-care CVD risk reduction intervention (HeartHealth) designed to improve multiple CVD risk factors while overcoming barriers to success with (2) referral of patients to a primary care provider for management of their CVD risk factors. The investigators propose the following specific aims to be tested at 4 months and 1 year after baseline. To compare the short and long-term impact of the interventions on: 1) the risk factor selected by patients (i.e., tobacco use, blood pressure, lipid profile, hemoglobin-A1c (HgA1c) for diabetics, body mass index, waist circumference, depressive symptoms, or physical activity level); 2) all of the CVD risk factors of each patient; 3) quality of life; 4) patient and healthcare provider satisfaction; 5) desirability and adoptability by assessing adherence to recommended CVD risk reduction measures, and retention of recruited individuals. The investigators hypothesize that in comparison to the referral strategy, the multifaceted patient-centered, self-care intervention will engender more favorable outcomes across all measures.

This study will assess the efficacy and safety of multiple doses of LCZ696 compared to olmesartan in Asian patients with essential hypertension

This study examines the long term safety and efficacy of the Fixed Dose combination BAY98-7106 (nifedipine plus candesartan primarily at the highest dose in development) in patients with moderate to severe hypertension. Patients meeting the entry criteria, will receive the Fixed Dose combination for 28 weeks, including 8 weeks with stepwise dose increase up to the high target dose. The first 200 subjects completing 28 weeks will continue treatment for additional 24 weeks (52 weeks in total). Subjects who do not tolerate an increased dose will be treated at their highest tolerable dose.

Background: In hypertension, a highly prevalent disease, up to 10-15% of hypertensive patients have uncontrolled blood pressure despite a regimen of ≥ 3 drugs, which is known as resistant hypertension (RH). Cardiovascular prognosis in patients with RH is worse than in controlled hypertensives. Efferent renal sympathetic nerves play an important role in volume homeostasis and blood pressure. A novel minimally invasive technique based on the use of selective radiofrequency renal sympathetic denervation has shown promising preliminary results for the treatment of these patients. On the other hand, some patients with RH could improve their blood pressure control by adding spironolactone, an antagonist of aldosterone receptors. Objective: To evaluate the efficacy of radiofrequency renal sympathetic denervation in patients with RH, as compared with the addition of spironolactone to the therapeutic regimen at baseline. Method: interventional, prospective, randomized, open study, of a cohort of 50 patients with RH, with office systolic blood pressure ≥ 150 mmHg and also with 24h systolic blood pressure ≥ 140 mmHg, despite treatment with ≥ 3 drugs in adequate doses, one of them a diuretic, and whitout treatment with either spironolactone or eplerenone. Patients will be randomized (1:1) to renal sympathetic denervation treatment or spironolactone (50mg), performing determination of office blood pressure and 24h-ABPM at pre-randomization, 1, 3 and 6 months, as well as laboratory tests, echocardiography, measurement of carotid intima-media thickness and central blood pressure measurement at pre-randomization and after 6 months.

To test the hypothesis that hypertensive patients who participate in smart phone based telemonitoring of BP will conduct more home blood pressure monitoring, better self management behavior and greater reduction in blood pressure and better self management behaviour from baseline to 6 months follow up than those patients receiving enhanced usual care.

To provide continued treatment to Pulmonary Arterial Hypertension (PAH) patients who are benefitting from treatment with QTI571.

The REALISE trial is a single-arm, open-label, prospective, post market evaluation to be conducted on twenty (20) eligible patients with a twelve month follow-up period.

The primary objective of this study is to investigate incremental cost effectiveness of Nifedipine CR and Amlodipine in combination therapy with Valsartan for the treatment of essential hypertensive patients. To investigate incremental cost effectiveness, primary variables are mean treatment cost and achievement rate to target blood pressure level at the end of double-blind treatment period.
