2,313 Clinical Trials for Various Conditions
Pulmonary arterial hypertension (PAH) is a type of high blood pressure in the arteries that carry blood from the heart to the lungs. PAH occurs when the openings in the blood vessels of the lungs get smaller and smaller. These smaller openings can be caused by the following: * The walls of the arteries tightening * The walls of the arteries becoming stiff and narrow from an overgrowth of cells The increased pressure in the pulmonary arteries strains the right side of the heart and it begins to fail, causing difficulty breathing and other symptoms. As PAH progresses, symptoms get worse. There is no cure for PAH, but several medications like endothelin receptor antagonists (ERAs), prostacyclin analogues (PCAs) and riociguat, a soluable guanylate cyclase stimulator, are available to help slow the progression of changes in the pulmonary arteries and help reduce symptoms. Riociguat can be taken together with ERAs and PCAs. In this study, the researchers want to learn about how well riociguat works, how safe it is when patients take it in 1 of these ways: * alone * with ERA * with PCA * with ERA and PCA The dosage for each patient will be decided by their doctor. The researchers will review information collected from the patients who have decided with their doctor to start riociguat treatment for their PAH. The study will include about 500 patients in the United States who are at least 18 years old. All of the patients will have either just started taking riociguat or will have been taking it for less than 3 months No investigational products will be administered in this study. Patients will be treated with the Standard of Care (SOC) for PAH. The SOC is the currently appropriate treatment in accordance with scientific evidence and agreed upon in collaboration between medical experts for PAH. There will be no study-mandated visits or treatments. The patients will be in the study for up to 2 years. During this time, they will visit their doctor every 3 to 6 months as part of the Standard of Care. At these visits, the patients will answer questions about their PAH symptoms and whether they have any medical problems. They will also do exercise tests to see how well they are able to breathe and how tired they get while exercising. The doctors will perform other usual examinations which are part of the Standard of Care such as echocardiograms (images of the heart to show how the heart is working) and a right heart catheters (to measure the pressures in the heart) and will take the usual blood and urine samples.
Pulmonary Arterial Hypertension
The goal of this clinical trial is to show the blood pressure lowering effect of aprocitentan, a new drug, when added to other anti-hypertensive drugs of patients with difficult to control (resistant) high blood pressure (hypertension), and to show that blood pressure reduction is kept for long period of time.

Pulmonary Arterial Hypertension
Our goal is to determine clinically in Pulmonary Arterial Hypertension patients if associations exist between the efficacy and toxicity of sitaxsentan, bosentan, and ambrisentan and several gene polymorphisms in several key disease-specific and therapy specific genes. Also characterized is the relationship between these polymorphisms and the severity of Pulmonary Arterial Hypertension using either baseline hemodynamic or clinical surrogates for disease severity. Hypothesis: Polymorphisms influence the efficacy and toxicity of specific Pulmonary Arterial Hypertension therapy as well as development/severity of PAH via their effect on PA remodeling, drug response, or metabolism. This study requires a one time 8.5 ml blood sample and clinical data to be obtained at initiation of therapy, 4 months after initiation of therapy and 12 months after initiation of therapy.
Pulmonary Arterial Hypertension, Pulmonary Hypertension, PAH WHO Group I
Pulmonary arterial hypertension (PAH) is a severe disease with a delayed diagnosis and markedly elevated mortality. High-risk populations, such as those with known genetic defects, provide a unique opportunity to determine the features of susceptibility and resilience to PAH. This proposal will fundamentally overturn the prevailing understanding of PAH by creating molecularly-driven signatures of susceptibility and resilience, provide novel insight into disease severity, and potentially identify new therapeutic targets.

Pulmonary Arterial Hypertension (PAH)
Patients with Group 1 pulmonary hypertension will be enrolled in this study. Investigators will test the hypothesis of low-level tragal stimulation in patients with pulmonary hypertension. The study will be conducted over 4 weeks and patients will undergo low-level tragus stimulation for 1 hour every day for 4 weeks. At baseline the following tests will be conducted-6-minute walk distance, vascular function testing using noninvasive device and blood samples will be collected. Patient will also undergo a limited echocardiography to assess right ventricular function. After 4 weeks of stimulation patients will come back to undergo these tests again. Investigators hypothesized that low-level tragus stimulation (neuromodulation) will lead to improvement in vascular function, 6-minute walk distance and blood based biomarkers in patients with pulmonary hypertension.
Pulmonary Hypertension
Researchers are looking for other ways to treat people with PAH. In PAH, the blood vessels in the lungs become thick and narrow, which makes it harder for blood to flow to the lungs. The goal of the study is to learn: * What happens to different doses of sotatercept in a person's body over time when it is given using weight-banded doses compared to weight-based doses. There may be differences in how the medicine works with the new dosing method (weight-banded dosing) being studied in this trial. * About the safety of sotatercept and if people tolerate it

The purpose of this study is to test new technology and health coaching aimed to help people with PAH become more physically active in their daily lives.
Pulmonary Arterial Hypertension
Patients with pulmonary arterial hypertension (PAH) have reduced health related quality of life (HRQOL) and impaired exercise capacity. Despite fourteen approved therapies, most patients die within ten years. Increasing physical activity is highly efficacious in PAH, resulting in six-minute walk distance (6MWD) and HRQOL improvement that often exceeds the effect of medications. Prior activity studies required inpatient rehabilitation, which is impractical, hard to sustain, and poorly scalable to a rare disease. The Investigators propose a randomized trial of smart texts versus usual care for 6 months. The Investigators will randomize 100 PAH patients to the mHealth intervention or usual care. The Investigators will test the effect of a text-based mHealth intervention on HRQOL in PAH using the PAH-specific emPHasis-10 questionnaire. The Investigators will also test the effect of an mHealth intervention on exercise capacity, measured by a supervised home-based 6MWD test. Finally, the Investigators will examine the effect of the intervention on time to clinical worsening (composite of PAH therapy escalation, PAH hospitalization, and death) one year after randomization.

Idiopathic Pulmonary Arterial Hypertension, Heritable Pulmonary Arterial Hypertension, Pulmonary Arterial Hypertension Associated With Connective Tissue Disease
Pulmonary arterial hypertension (PAH) is a disease where the blood pressure in the pulmonary arteries (PAP) is high. PAH increases the risk of adverse events, including death, during and or after procedures. The severity of baseline PAH correlates with the incidence of major complications, such that those with PAP higher than their systemic blood pressure (SBP) had a 8 fold increased risk of complications. These children present for procedures where an acute exacerbation of their chronic illness-termed Pulmonary Hypertensive (PH)crisis, can occur, often resulting in death if not detected and managed expeditiously. Unfortunately there is little data and no consensus in the pediatric literature on how PH crisis should be managed. --------------------------------------------------------------------------------

IMPAHCT: Inhaled iMatinib Pulmonary Arterial Hypertension Clinical Trial is a Phase 2b/Phase 3 study to evaluate the safety and efficacy of AV-101 (dry powder inhaled imatinib) in patients with Pulmonary Arterial Hypertension (PAH). The Phase 2b part of the study will assess three doses to establish an optimal dose for the Phase 3 part of the study. The Phase 2b primary endpoint will be the placebo corrected change in pulmonary vascular resistance (PVR). The Phase 3 primary endpoint will be the placebo corrected change in 6-minute walk distance (6MWD) after 24 weeks of treatment.
Pulmonary Arterial Hypertension
Pulmonary arterial hypertension (PAH) is a progressive disease in which clinically relevant symptoms present a few years after the onset in rise of pulmonary arterial pressure. Increased PA pressure presents an overload on the right ventricle (RV), with RV failure being a common cause of mortality in PAH. Current therapeutic targets help reduce vascular resistance and RV afterload, however, RV dysfunction may continue to progress. Therefore, the reason for RV failure in PAH cannot be contributed to altered vascular hemodynamics alone but may be related to metabolic alterations and failure of adaptive mechanisms in the RV. Providing a better understanding of metabolic remodeling in RV failure may permit the development of RV-targeted pharmacological agents to maintain RV function despite increased pulmonary vascular pressures. This study will evaluate how cardiac metabolism changes in response to pulmonary vasodilator therapy in patients with pulmonary arterial hypertension.
