NCT00159874
Active treatment, dose-blinded extension study evaluating the safety and long term efficacy of sildenafil citrate in children with PAH.
NCT04092959
A total of 240 hypertensive subjects aged 40-69 years (including 126 patients complicated with diabetes) will be included in a few communities in Beijing, and will be divided into 3 groups according to the individual wishes of the subjects: walking group(n=80, including 42 patients complicated with diabetes), Chinese square dancing group(n=80, including 42 patients complicated with diabetes) and control group(n=80, including 42 patients complicated with diabetes). All exercise sessions will be supervised and subject's exercise implementation process will be managed with intelligent equipment. The purpose of the study is to evaluate the effectiveness and safety of different training programs in the real world. The demographics data, physical activity questionnaires, blood pressure, blood glucose, blood lipids, height, weight and physical fitness （cardiorespiratory fitness,muscle strength, muscle endurance, flexibility, body composition)will be measured before and after 3-month exercise training .The adverse reactions in the implementation of the interventions will be recorded. The primary outcomes are blood pressure and blood glucose.
NCT00150358
To assess changes with respect to Erectile Dysfunction in subjects treated with Viagra and antihypertensive therapy.
NCT00644605
To evaluate the effect of three doses of oral sildenafil (20, 40 and 80 mg three times a day \[TID\]) on exercise capacity, as measured by the 6-Minute Walk test, as well as the safety and tolerability, after 12 weeks of treatment in subjects with pulmonary arterial hypertension who are aged 18 years and over. To investigate the plasma concentration-effect relationship and to determine the population pharmacokinetic (PK) parameters.
NCT00800592
The objective of this study is to assess the safety, tolerability and pharmacokinetics of intravenous sildenafil (10 mg) administered as a bolus injection to patients with Pulmonary Arterial Hypertension already receiving and stable on oral Revatio 20 mg TID.
NCT02519868
High blood pressure, also referred to as hypertension, affects about 65 million people in the United States alone. Approximately 25 percent of people with hypertension cannot control their high blood pressure, despite the use of multiple medications. Recently, new evidence has demonstrated that the carotid body (CB) plays a role in essential refractory hypertension, possibly due to a deregulated, enhanced activity of this organ. Animal studies showed that CB de-afferentiation, through carotid sinus nerve denervation, leads to a long-term stable drop in blood pressure in spontaneously hypertensive rats. De-afferentiation may be performed either by injecting local anesthetics or by electrical stimulation. Both techniques are daily used in the operating theater to anesthetize nerves for a wide range of surgical procedures. We hypothesize that blocking CB with local anesthetics will result in a drop of the blood pressure in refractory hypertensive patients. We also want to test the idea that stimulating the CB with an electrical current will mislead the CB and will also result in a drop of the blood pressure.
NCT04117204
This study will evaluate providing fruits and vegetables in a sustainable community care clinic setting, in addition to routine medical care, to individuals with CKD (Stage 2-4) on CKD and CVD risk, or cardio-renal risk factors. Further, metabolomics profiling will be used to study how change in the diet affects disease risk. Data from this study will be published in peer-reviewed journals, presented at national conferences, and will serve as pilot data to guide and strengthen applications for NIH funding.
NCT00646841
The primary objective was to determine the effects of the Gastrointestinal Therapeutic System (GITS) formulation of Doxazosin when used in combination therapy with the 5 major classes of antihypertensive agents as measure by 24-hour diastolic blood pressure.
NCT01582438
The purpose of this study is to provide sildenafil therapy to subjects who have completed the A1481156 study for the treatment of Pulmonary Arterial Hypertension (PAH) in India and are judged by the Investigator to derive clinical benefit from continued treatment with sildenafil citrate. Sildenafil citrate will be supplied for the treatment of Pulmonary Arterial Hypertension (PAH) until the subject continues to derive benefits from the treatment. The treating physicians (and the sponsor) will be responsible for reporting serious adverse events.
NCT03926975
The purpose of this study is to evaluate the use of two instruments to measure changes in two ocular structures: 1) the anterior chamber depth (ACD) - measured using low coherence optical biometry, and 2) minimum rim width of the optic nerve head (MRW) - measured using optical coherence tomography. Changes in these ocular structures indicate fluctuations in intraocular pressure (IOP) and will be measured during scleral contact lens (SGP) wear to determine if SGP wear influences IOP. We hypothesize that a scleral lens increases the intraocular pressure (IOP) during active wear and that the ACD and MRW will also change.
NCT04729777
What problems limit patients' response to exercise? Using exercise cardiac magnetic resonance imaging to assess the heart's response, with simultaneous measurement of respiratory oxygen and carbon dioxide levels to assess the lung and skeletal muscle responses, to identify the rate-limiting factors affecting different types of patient
NCT01190007
The primary objective is to investigate the safety of Caduet (2.5 mg/5 mg, 2.5 mg/10 mg, 5 mg/5 mg or 5 mg/10 mg as dose of Amlodipine/Atorvastatin) during 52 weeks treatment period in Japanese patients with both of hypertension and hypercholesterolemia, or with both angina pectoris and hypercholesterolemia.
NCT01792622
Develop a brief, new, patient reported outcome instrument that is valid for use in clinical practice and clinical trials.
NCT01107743
In this survey, to collect the safety and efficacy information of Amlodipine /Atorvastatin (Caduet® Combination Tablets) in daily medical practice will be examined. In addition, the necessity of special Investigation and post-marketing clinical studies will be examined, while investigating unexpected adverse drug reactions during the survey period and understanding of the status of frequency of adverse drug reactions in daily medical practice.
NCT01252563
In this survey, to collect the safety and efficacy information in the subjects who have been treated with amlodipine 5mg at least 4 weeks in daily practice.
NCT00159692
To evaluate the percentage of subjects that reach the diabetic hypertensive blood pressure goal of \<130/80 with amlodipine versus placebo in subjects initially treated with quinapril or losartan.
NCT00143234
The purpose of the study is to measure the effect of the amlodipine/atorvastatin combination pill in reducing both elevated blood pressure and cholesterol levels to levels suggested by guidelines
NCT02634203
"Chronic thromboembolic pulmonary hypertension (CTEPH) is a severe form of pulmonary hypertension characterized by obstruction of the pulmonary vasculature by residual organized thrombi, leading to increased pulmonary vascular resistance (PVR), progressive pulmonary hypertension, and right failure. In patients deemed operable, pulmonary endarterectomy (PEA) is the gold standard treatment and is the only potentially curative treatment. However, some patients are ineligible for surgery owing to occlusion of distal vessels. The best treatment option for these non-operable CTEPH patients is not yet established.
NCT04554069
Assessment of the influence of different antihypertensive drugs on serum uric acid in newly diagnosed hypertension patients.
NCT04715698
