Active clinical trials for "Pulmonary Arterial Hypertension"

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.

Prospective registry including incident patients and prevalent patients which pretends to identify clinical characteristics, treatment trends in-hospital and ten years follow-up outcome through major adverse cardiovascular events (MACE) in a China population with well characterized PAH.

Pulmonary hypertension represents a challenging and heterogeneous condition that is associated with high mortality and morbidity if left untreated. Artificial intelligence is used to study and develop theories and methods that simulate and extend human intelligence, which is being applied in fields related to cardiovascular diseases. The study intends to combine multimodal clinical data of patients who undergo right heart catheterization at Fuwai Hospital with artificial intelligence techniques to create programs that can screen and diagnose pulmonary hypertension.

This is an observational, ambrispective study of patients in real world clinical practice, who has pulmonary arterial hypertension in whom a prostacyclin IP receptor agonist (Selexipag) is initiated between 2017 and 2021. The aim of this study answer the following questions: Changes in the mortality risk profile of these patients after treatment administration. Baseline characteristics of patients initiating Selexipag. Parameters used for risk stratification prior to treatment escalation. Events during follow-up. No comparison group available

The aim of this study is to determine whether there is an increase in the TSPO PET signal (measured with the radioligand [11C]PBR28) in the lungs of patients living with PAH relative to age matched controls. If so, TSPO PET may be a useful technique to non-invasively monitor response to therapy. To do this, we will perform 2 [11C]PBR28 PET scans. The first will quantify the total [11C]PBR28 PET signal. This signal is a combination of the specific signal (VS) and the nonspecific signal (VND). The second scan will be performed following dosing with an unlabelled TSPO ligand. By directly measuring the total [11C]PBR28 signal (scan 1) and the nonspecific [11C]PBR28 signal (scan 2) we can therefore calculate the specific [11C]PBR28 signal, and hence the amount of TSPO in the lung.

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.

The RECONNECTIVE Registry is an observational single center study, focused on the subgroup of precapillary pulmonary hypertension related to connective tissue diseases. All patients will have hemodynamic confirmation by right heart catheterization and will be follow-up for at least 5 years from admission. All patients diagnosed with Group I Pulmonary Arterial Hypertension (PAH) associated with Connective Tissue Diseases (CTD) and Group IV Pulmonary Hypertension (PH) with CTD will be included. The purpose of the registry is to learn and understand the clinical outcomes and natural history of the pulmonary arterial hypertension in this subgroup of patients to improve the medical care and treatment.

Cardiac remote monitoring devices have expanded our ability to track physiological changes used in the diagnosis and management of patients with cardiac disease. Implantable remote monitoring technologies have been shown to predict heart failure events, and guide therapy to reduce heart failure hospitalizations. The CardioMEMs System, the most studied and established remote monitoring system, relies on a pulmonary artery implant for continuous PAP measurement. However, there are no commercially available wearable systems that can reproduce continuous PAP tracings. This study aims to determine if a machine-learning algorithm with data from a wearable cardiac remote-monitoring system incorporating EKG, heart sounds, and thoracic impedance can reproduce a continuous PAP tracing obtained during right heart catheterization.

The study aim to assess right atrial (RA) remodeling, in terms of RA fibrosis, in pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension patients. This will be investigated in detail with in-depth cardiac magnet resonance imaging (CMRI). A cohort with exclusion of pulmonary hypertension which underwent CMRI due to dyspnoe of unkown reason will be the control group.

To observe and assess drug administration activities, time spent on drug administration activities, and patient-reported outcomes (PROs) including quality of life, treatment satisfaction, and patient perception of devices related to use of United Therapeutics Corporation (UTC)-developed next-generation infusion pumps to administer Remodulin in patients with Pulmonary Arterial Hypertension (PAH).
