Filter by:Multicenter, Open-label, Non-comparative, Proof-of-concept, Phase 2a Study to Evaluate the Effect of a Single Infusion of Tezosentan on Pulmonary Vascular Resistance in Patients With Stable, Chronic Pulmonary Arterial Hypertension, Currently Not Treated With Endothelin Receptor Antagonists, Phosphodiesterase-5 Inhibitors or Prostacyclines
Clinical dose escalation drug trial to evaluate the effect of 3 different doses of dexmedetomidine on the pulmonary vascular bed in pediatric subjects with elevated pulmonary vascular resistance (PVR). The study will be conducted in 2 parts, with part 1 incorporating stopping rules to optimize safety of the drug in this population. The second part of this study will evaluate if the lowest safest dose, as determined in part 1, is adequate to provide effective sedation during a cardiac catheterization procedure.
Sildenafil is efficacious in newborns with persistent pulmonary hypertension and its use will reduce the need for inhaled nitric oxide.
The aim of this study is to assess whether oral Riociguat affects the left ventricular contractility and relaxation in patients with pulmonary hypertension associated with left ventricular systolic dysfunction
Almost 50% of hypertensive patients remain uncontrolled. Clinical decisions are mostly based on office blood pressure,despite the fallacies of this method of measurement. Other reasons for not achieving blood pressure targets are lack of 24-hr efficacy and tolerability of existing anti-hypertensive drug classes. Aliskiren (Rasilez®) is a new antihypertensive drug, given once a day. The purpose of the REALITY study-[tREAtment of essentiaL hypertension with rasIlez. evaluation of different methods of blood pressure measurements - efficacy and safeTY evaluation -] is to evaluate the efficacy, and tolerability of aliskiren in a "real life" setting. The efficacy of the drug will be evaluated using 24 hour ambulatory blood pressure monitoring (ABPM). Results will be compared with office, nurse or self blood pressure monitoring. This comparison will allow to decide which follow-up technique is better for those hypertensive patients.
Sickle cell disease (SCD) is often referred to as a hypercoagulable state. However, the contribution of coagulation activation to the pathogenesis of SCD remains uncertain. Pulmonary hypertension (PHT) is a common complication associated with significant morbidity and mortality. Autopsy studies of SCD patients with PHT show evidence of in situ thrombosis involving pulmonary vessels, similar to findings in non-sickle cell patients with PHT. Anticoagulation has been reported to be of benefit in non-sickle cell patients with PHT. With the evidence of increased coagulation activation in SCD, PHT represents a clinical endpoint that may be used to evaluate the contribution of coagulation activation to the pathophysiology of SCD. The investigators hypothesize that increased thrombin generation, as well as platelet activation are central to the pathophysiology of SCD and contribute to the occurrence of several SCD-related complications, including PHT. As a consequence, treatment modalities that down-regulate thrombin generation would be expected to delay the progression of PHT and result in improved survival in patients with SCD.
The purpose of this study is to compare the effect on systolic pressure of the 3 drugs given together in the cardiovascular combination pill (acetylsalicylic acid, simvastatin, and ramipril) to the effect on systolic pressure of ramipril given alone.
The Thelin Patient Safety Registry is a post-marketing program in the European Union (EU) that is designed to supplement the reporting of spontaneous adverse events (AE) and better characterize known and potential safety signals for Thelin. The registry is a secure, restricted access, electronic system which collects anonymous, pre-defined, patient-level data on demographic variables, safety monitoring measurements (i.e. liver function tests, haemoglobin and international normalized ratio (INR) measurements), concomitant medications, information on AEs and Thelin drug discontinuation. Regular review of the data is conducted to assess the frequency of identified safety risks and to monitor for the emergence of new safety signals at monthly pharmacovigilance meetings, quarterly signal detection meetings, and for each Periodic Safety Update Report (PSUR).
The goal of this project is to investigate the effects that the addition of aldosterone blockade with eplerenone will have on the progression of diastolic dysfunction in patients with controlled essential hypertension.
This study is designed to assess how rapidly and how safely Clevidipine can be used to control high Blood Pressure in patients with subarachnoid hemorrhage which is a type of brain bleed that happens because of a weak balloon like structure in one of the brain vessels. Control of blood pressure is of high value in preventing this balloon that ruptured and bled from rebleeding. The ultimate cure would be to shut down the aneurysm by a surgical procedure. Clevidipine is a drug that can lower blood pressure and it is given through the vein as a continuous infusion. It is a very short acting drug which is important in controlling labile blood pressure condition with rapid changes between up and down. This trial will test for its rapid actions and check for any side effects and possibly any other potential benefit.
