  • Mono vs. Dual Therapy for Pediatric Pulmonary Arterial Hypertension

    open to eligible people ages 4 months to 18 years

    The investigators' central hypothesis is that early combination therapy with two PAH-specific oral therapies that have been shown to be well tolerated in the pediatric population, sildenafil and bosentan, will result in better World Health Organization (WHO) functional class at 12 months after initiation of PAH treatment than therapy with sildenafil alone.

  • Right Ventricular Pacing in Pulmonary Arterial Hypertension

    open to eligible people ages 18-75

    In pulmonary arterial hypertension (PAH), progressive pulmonary vascular remodeling leads to supraphysiologic right ventricular (RV) afterload. Pharmacologic trials have shown that aggressive upfront treatment reversing pulmonary vascular remodeling successfully increases RV function and improves survival. To date, however, there are no proven treatments that target RV contractile function. Echocardiographic studies of RV dysfunction in the setting of pressure overload have demonstrated intra and interventricular dyssynchrony even in the absence of overt right bundle branch block (RBBB). Electrophysiologic studies of patients with chronic thromboembolic disease (CTEPH) at the time of pulmonary endarterectomy have shown prolongation of action potential and slowed conduction in the right ventricle which has correlated with echocardiographic measures of dyssynchrony. Cardiac MRI measures of RV strain in patients with PAH demonstrated simultaneous initiation of RV and left ventricular (LV) contraction, but delayed peak RV strain suggesting that interventricular dyssynchrony is a mechanical rather than electrical phenomenon. Prior studies of RV dysfunction in an animal model, computer model, congenital heart disease, and CTEPH have suggested acute hemodynamic benefits of RV pacing. However, RV pacing has not been studied in patients with PAH. Furthermore, it remains unclear if pacing particular regions of the RV can achieve a hemodynamic benefit and what cost this hemodynamic improvement may incur with regards to myocardial energetics and wall stress. Therefore, the investigators propose to examine RV electrical activation in PAH, map the area of latest activation, and then evaluate the hemodynamic and energetic effects of RV pacing in these patients.

  • Pediatric Pulmonary Hypertension Network (PPHNet) Informatics Registry

    open to eligible people ages up to 21 years

    Patients are being asked to be in this research study because medical researchers hope that by gathering information about a large number of children with pulmonary hypertension over time, their understanding of the disease process will increase and lead to better treatment. Investigators believe that pulmonary hypertension in children is different than pulmonary hypertension in adults and this study will help us understand those differences.

  • Pulmonary Hypertension Association Registry

    open to all eligible people

    The PHA Registry (PHAR) is a national study about people who have pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). PHAR collects information from people with PAH and CTEPH who are cared for in participating PHA-accredited Pulmonary Hypertension Care Centers throughout the U.S. PHAR will determine how people with PAH and CTEPH are evaluated, tested, and treated, and will observe how well these participants do. The goal is to see if people with PH are treated according to recommended guidelines, and to see if there are certain factors that can lead to better or worse outcomes. PHAR will include information about people with PAH and CTEPH in the U.S. who are seen at participating PHA-accredited PH Care Centers. PHAR contains data about patient care and outcomes. Specifically, data in the PHAR includes information on diagnosis; clinical status; socioeconomic status; diagnosis test results; body size; treatment information; interest in participating in clinical trials; family health and social history; and information about smoking, alcohol, or drug use. Participants are followed over time, and provide updates such as changes in therapy, how often participants need to go to the hospital, and survival. Such information may help healthcare providers provide better care.

  • A Long-term Follow-up Study of Sotatercept for PAH Treatment (MK-7962-004)

    Sorry, not currently recruiting here

    This study is being conducted to assess the long-term safety, tolerability, and efficacy of sotatercept in participants with Pulmonary Arterial Hypertension (PAH). This open-label, long-term follow-up (LTFU) study is supported by data from the PULSAR study (Phase 2, NCT03496207) in which treatment with sotatercept resulted in hemodynamic and functional improvements in the study participants, including those receiving maximal PAH therapy with double/triple drug combinations and intravenous prostacyclin. The primary objective of this open-label, LTFU study is to evaluate the long-term safety and tolerability of sotatercept when added to background PAH therapy in adult participants with PAH who have completed prior sotatercept studies. The secondary objective is to evaluate continued efficacy in adult participants with PAH who have completed prior sotatercept studies.

  • A Study to Learn About How Well Riociguat Works, How Safe it is and How it is Used Under Real World Conditions in Patients in the United States Who Are Receiving Riociguat for High Blood Pressure in the Arteries That Carry Blood From the Heart to the Lungs (Pulmonary Arterial Hypertension, PAH)

    Sorry, not currently recruiting here

    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.
