NCT00890591
In patients naive to treatment or after a 2-week washout period for patients whose treatment was ineffective, the use of olmesartan was assessed in a 4-phase treatment scheme: monotherapy, addition of hydrochlorothiazide (2 phases), addition of amlodipine.
NCT00374829
The study is a randomised controlled trial to evaluate the impact of a program using information technology (IT) and healthcare professional support in patients with high blood pressure (BP) compared to usual care. The program helps patients monitor their own BP and medication and keeps nurses,physicians and pharmacists informed while respecting patient confidentiality. The IT system links directly with the patient's pharmacy data. Using pharmacy data and responses to questions on compliance and BP control, the IT system provides appropriate counselling, telephone reminders, generates prescription refill and renewal reminder calls and monitors BP. The system reports compliance and self recorded BP measurements to healthcare providers and also links with a nurse. This is so that the nurse, the patient's doctor and pharmacist can help answer questions about medication and controlling high blood pressure. A total of 500 patients in Laval, Quebec will participate in the study. Half of the patients will have the program plus usual care and the other have usual care only. We hypothesize that the program will improve BP control by helping patients take their medication properly and by helping doctors ensure that the best strength and kinds of medication are used to control high blood pressure. We believe the program will achieve this by helping to improve communication between patients and healthcare providers, without adversely impacting quality of life. Additional sub-studies will determine if the program is cost effective and can be applied in real practice and if the program helps patients, doctors, pharmacists and nurses communicate better.
NCT00656240
To investigate the intraocular pressure (IOP)-lowering effect and safety of DE-104 ophthalmic solution in patients with Primary Open-Angle Glaucoma or Ocular Hypertension
NCT00852514
Peritoneal dialysis (PD) is a widely used modality of renal replacement therapy. Due to its continuous nature of therapy, better control of fluid status and preservation of residual renal function were presumed by most nephrologists. However, recent evidences showed that it might not be the case. The severity of fluid overloading and the need for anti-hypertensive agents to control blood pressure seems to be more severe for PD patients. Therefore, more aggressive strategy to control dry weight is mandatory in PD patients. However, over reduction of dry weight might affect residual renal function (RRF) and, probably, the survival of PD patients. A balance between reduction of dry weight and preservation of RRF is crucial for the care of PD patients. Currently, only clinical measures like cardiothoracic ratio on chest X-ray and absence of pedal edema were used to evaluate PD patient's dry weight. There is no objective method to determine dry weight accurately. In this prospective and randomized study, the investigators will use multi-frequency bio-impedance (MF-BIA) to detect intracellular and extracellular water (ECW) content of patients.
NCT00409253
The aim of this study is to confirm that URAPIDIL is as efficient and as safe as NICARDIPINE to correct severe hypertension in pre-eclamptic patients. * efficacy endpoint : mean arterial blood pressure corrected to 105-125 mmHg after 120 min of study drug administration. * safety endpoints : clinical, biological and ultrasound observation for any side effect.All infants will be observed in the neonatology unit (during 48h).
NCT00160277
The purpose of this study is to demonstrate efficacy and safety of Moxonidine in Indian subjects.
NCT00160160
This study is to demonstrate the superiority of combination of eprosartan/HCTZ versus ramipril/HCTZ.
NCT00559286
The hypothesis of the presented study is: Telmisartan induces an increase of eNOS activity in RBC resulting in an enhanced intravascular NO bioavailability, an ameliorated RBC deformability and a reduction of RBC and platelet aggregation. This could be a potential mechanism of the improvement of microcirculatory disorders, especially in patients with diabetes mellitus and arterial hypertension, treated with Telmisartan.
NCT00459914
A small number of uncontrolled studies have shown a high prevalence of sleep apnea in patients with refractory hypertension and that CPAP treatment achieves a significant reduction of blood pressure in the short term. The purpose of this study is to assess the prevalence of sleep apnea in patients with refractory hypertension, and the effects of continuous positive pressure treatment on systemic blood pressure and on serum markers of endothelial dysfunction and angiogenesis.
NCT00018304
The overall objective of this proposal is to examine the contribution of changes in total body fat, enhancement in insulin-mediated vasodilatation and enhancement in endothelium-derived nitric oxide production to the improvements in metabolic insulin action. In addition, the study will track whether these improvements are related to changes in blood pressure.
NCT00302705
This study was designed in order to evaluate the blood pressure lowering effect of valsartan compared to enalapril over 24 hours after skipping one daily dose. Both drugs act on the renin-angiotensin-aldosterone system (RAAS) and are widely use for the treatment of hypertension. Previous studies had a significant limitation: the effect of a missing dose was not evaluated after the whole 24 hours post missing dose period (48 hours after last taken dose), and as a result, it does not imitate the real life situation of a missing dose.
NCT00809666
The aim of the PRAM study was to determine whether women diagnosed with hypertension in pregnancy, using the traditional mercury device, have the same pregnancy outcomes when blood pressure is measured by either an automated device or a mercury device throughout the pregnancy.
NCT00800228
The purpose of this study is to test the hypothesis that blood pressure sensitivity to high sodium intake in healthy humans is characterized by increased urinary excretion of two endogenous sodium pump inhibitors, marinobufagenin (MBG), and ouabain-like compound (OLC). The study also tests the hypothesis that women who breathe slowly and have high resting end tidal CO2 at rest are more likely to have low plasma renin activity and sodium sensitivity of blood pressure than those who breathe more rapidly and maintain lower end tidal CO2.
NCT00469365
Compare the effectiveness of 3 strategies by pharmacists to decrease the time to refill of prescriptions for common chronic diseases (diabetes, hypertension, hyperlipidemia, heart failure, depression, psychoses).
NCT00511888
BACKGROUND Beta-blockers improve left ventricular (LV) systolic function and prognosis in patients with chronic heart failure. Both carvedilol and nebivolol have hemodynamic and clinical benefits in chronic heart failure (CHF), but it is unknown whether their pleiotropic properties may play a role in different subgroups of patients with CHF. OBJECTIVE: To compare the effects of nebivolol and carvedilol on LV function and clinical outcome in patients with chronic heart failure and reduced LV systolic function. METHODS: 160 hypertensive CHF patients, LV ejection fraction (EF) 40% and in New York Heart Association (NYHA) functional class II or III were randomly assigned to receive carvedilol or nebivolol therapy for 24 months. At baseline and after 24 months of treatment, all patients underwent clinical evaluation: echocardiogram and 6-minute walking test.
NCT00760110
Previous cross-sectional studies have demonstrated that blood pressure (BP) measurements at home (HBP) in the morning offer stronger predictive power for micro- and macrovascular complications in patients with type 1 and 2 diabetes than casual/clinic blood pressure measurements (CBP). The present study examined which of HBP or CBP provides the stronger predictive power for outcomes by comparing cumulative events between hypertensive and normotensive patients over 6 years in a prospective, longitudinal study of patients with type 2 diabetes.
NCT00497016
A number of patients with hypertension have increased central sympathetic activity. Statins seem to inhibit central sympathetic output. This study assesses the effect of statins on central sympathetic activity in hypertension patients.
NCT00693199
The aim of this study was to investigate the efficacy and safety of low dose amlodipine alone, or combined with low dose terazosin in male patients with both lower urinary tract symptoms and hypertension.
