NCT02298244
Some patients with a long history of AF develops PH "reactive" type with an increase in pulmonary vascular resistance due to vasoconstriction or structural changes of the vascular wall. RFA PVI + RFA GP is the "gold standard" in the treatment of patients with persistent AF, do not respond to optimal therapy. The rear area of the pulmonary artery bifurcation is adjacent to the roof and part of the front of the left atrium. In the projection of this area are ganglionic plexus of the left atrium, the sympathetic nerve fibers of the pulmonary artery and baroreceptors main pulmonary artery.Recent studies have shown that radiofrequency denervation of the pulmonary artery improves the quality of life in patients with PH.
NCT00753285
The purpose of this study is to investigate the clinical utility of renal denervation for the treatment of refractory hypertension.
NCT01172756
The aim of this study is to assess whether single oral doses of Riociguat safely improve the cardiovascular function in patients with pulmonary hypertension associated with left ventricular diastolic dysfunction
NCT02243514
Sympathetic hyperactivity is a causal or a promoting factor in many diseases, under these conditions, some morphology changes due to the hyperactivity occur. Renal nerve is an important part in the autonomic nervous system regulation, especially in cardiovascular system, the modulation of the renal nerves used as a therapeutic strategy has been researched across the world. The purpose of this study is to evaluate and quantify the morphology changes in different diseases, make the modulation therapy more selective and effective.
NCT01220336
Randomized control trial studying the effect of medical assistant health coaching for patients with diabetes, hypertension and hyperlipidemia within two San Francisco primary care community clinics, Mission Neighborhood Health Center and Southeast Health Center
NCT02078765
A new study have shown that high night time blood pressure (BP) and/or non-dipping (lack of fall in BP during night time) is a strong predictor for the risk of cardiovascular disease and mortality in patients with hypertension. Three factors seem to affect the night time BP: chronic kidney disease, obstructive sleep apnea (OSA) and the way ambulatory blood pressure is monitored. Hypothesis: Central 24-h blood pressure monitoring is a better way of monitoring blood pressure than conventional peripheral monitoring. In hypertension, chronic kidney disease and obstructive sleep apnea (OSA) the night time blood pressure is elevated, and is OSA the elevation is correlated to the severity of OSA. In OSA the kidneys handling of salt and water is disturbed. In OSA there is disturbances in hormonal balance.
NCT00574808
The aim of the proposed study is to implement and evaluate Outreach Facilitation as a means to increase the uptake of evidence-based practice for secondary prevention and management of patients with established CVD and cardiovascular risk factors, in primary care practices throughout the Champlain LHIN. This initiative centers on the use of an Outreach Facilitation Model, in which skilled health professionals known as facilitators (Practice Change Consultants) serve as an expert resource to primary care practices in three areas: a) practice performance assessment, feedback, and consensus building towards goal setting and implementation; b) clinical, technical, organizational resources and practical advice; and c) encouragement to face and move through the challenges associated with implementing system change.
NCT01896180
This is a pilot, proof of concept study to evaluate the safety and efficacy of ALZ-1101 dosed once daily for 28 days compared to latanoprost 0.005% ophthalmic solution in patients with elevated intraocular pressure not adequately controlled with latanoprost.
NCT01725945
Dietary intervention efficacy trials are distinctly lacking in asthma research. This pilot study aims to provide effect size estimates and justification, clinical trial and intervention feasibility data, and procedural materials for a full-scale randomized controlled trial that will determine the efficacy and mechanisms of action of the Dietary Approaches to Stop Hypertension (DASH)-a recommended dietary pattern based on proven cardiovascular benefits-as adjunct therapy to standard care for adults with uncontrolled asthma.
NCT02242396
The primary objective was to evaluate, through the use of Home blood pressure monitoring (HBPM), the degree of BP control in the early morning hours after 8 weeks of treatment in patients with essential hypertension under treatment with Micardis®, Telmisartan or Micardis Plus®, Telmisartan hydrochlorothiazide. The co-primary endpoints were the degree of BP control, and change from baseline until study end in mean systolic blood pressure (mSBP) and mean diastolic blood pressure (mDBP) HBPM in the early morning hours after 8 weeks of treatment with Micardis®, Telmisartan or Micardis Plus®, Telmisartan hydrochlorothiazide. Secondary endpoints were office BP control rates, office BP response rates, and reduction in mSBP and mDBP Office blood pressure measurement (OBPM) from baseline to final visit, discontinuations and tolerability
NCT02242812
The primary objective was to show that telmisartan is not inferior to metoprolol succinate in respect of the percentage change from baseline in LVMI(H) after a 6.5 months treatment period. As secondary objectives, the improvement in left ventricular systolic and diastolic function and blood pressure reduction were assessed
NCT02242318
The primary aim of the trial is to compare telmisartan 80 mg to valsartan 160 mg in lowering diastolic blood pressure in patients who missed a dose of their medication, as measured by ABPM (change from baseline in mean DBP over 24 hours), and to compare telmisartan 80 mg to valsartan 160 mg in lowering DBP during the last six hours of the dosing interval at the end of a 6 to 8-week treatment period, as measured by ABPM (change from baseline)
NCT00498433
Part 1 determined: aliskiren, amlodipine and angiotensin II concentrations in interstitial fluid of fat and skeletal muscle; aliskiren and angiotensin II concentrations, and renin activity and concentration in fat and skeletal muscle tissues (biopsies); aliskiren, amlodipine and angiotensin II concentrations, and renin activity and concentration in plasma. Part 2 investigated the potential for aliskiren to modulate renin-angiotensin-aldosterone system (RAAS) activity, and lipid/carbohydrate metabolism in adipose and skeletal muscle tissue in obese patients with hypertension in comparison to amlodipine.
NCT01880866
Pulmonary arterial hypertension (PAH) is a progressive disease that results in severe activity limitation and death. There are few treatments for PAH and the available medications are expensive, difficult to administer and have significant toxicities. (-)-Epicatechin is a non-toxic compound that naturally occurs in foods such as tea, wine and chocolate. Clinical intervention studies using dark chocolate in normal volunteers and subjects at risk for or with established cardiovascular disease have demonstrated improvements in peripheral and coronary vascular endothelial function, blood pressure, lipids, glucose tolerance and inflammatory markers. Our study intends to examine the hemodynamics effects of purified (-)-epicatechin in subjects with pulmonary arterial hypertension. We hypothesize purified (-)-epicatechin will reduce pulmonary vascular resistance in patients with pulmonary arterial hypertension.
NCT01566188
The overall aims of the present project are to investigate the impact of a nutritional approach based on omega-3 from vegetal origin on vascular function in hypertension associated with metabolic syndrome.
NCT01809821
Sleep is an essential component of good physical and mental health. Previous studies have reported that poor quality sleep is associated with an increased risk of hypertension, stroke and cardiovascular disease (CVD). Hypertension is the most common and important risk factor for CVD, and even modest reductions in blood pressure result in significant reductions in stroke and myocardial infarction. In this randomised trial, the investigators aim to evaluate whether a simple, multi-component, online sleep intervention reduces blood pressure in patients with essential hypertension.
NCT02229526
The initial trial examined if fish oil supplementation during pregnancy could reduce the risk of pregnancy induced hypertension, intrauterine growth retardation, and preterm birth in pregnancies that were at increased risk of these complications. The study was designed as a multi-centre clinical trial based in 19 hospitals in seven countries in Europe.
NCT01468545
Ventavis it's a treatment for pulmonary hypertension, administered by an inhaler called I-Neb. In these patients, the non compliance of the treatment becomes its ineffective and increases the complications and mortality of the disease. It is therefore important to know which the adherence of patients to their treatment is and try to promote it. One possibility to reach a good level of adherence is the patient education regarding the drug administration and also to comply as better is possible the recommendations of the physician. For this reason, the objective of our study is to demonstrate improvement in the level of treatment compliance when they follow a strategy of continuing education, assessed by the device and software called Insight. The only special procedure to participate in the study then is that patients involved could receive more training than usual. Investigators expect involving in this study around 50 patients in treatment with Ventavis and diagnosed of Pulmonary Arterial Hypertension in 10-12 hospitals throughout Spain. The patients who participated in the study will be followed for 12 months from inclusion in the study and will perform around 5 visits in total.
